The given compound inequality doesn't have any solutions because it creates a contradictory situation where x needs to be both greater than 9 and less than 0 at the same time, which is not possible.
Explanation:The given compound inequality is −33 > −3x − 6 ≥ −6. To find the equivalent form, let's solve it step by step.
First, add 6 to all sides, resulting in -27 > -3x > 0.
Then, divide by -3. Remember that when dividing by a negative number, the direction of the inequality changes. So, we get 9 < x < 0.
This indicates that x is greater than 9 but x also needs to be less than 0. This, however, is a contradictory situation because a number cannot be both greater than 9 and less than 0 at the same time. So, there are no solutions for this inequality.

An equivalent form of the compound inequality −33 > −3x − 6 ≥ −6 is x > 9.5 or x ≤ 0.
To find an equivalent form of the compound inequality −33 > −3x − 6 ≥ −6, we can break it down into two separate inequalities:
−33 > −3x − 6
−3x − 6 ≥ −6
To simplify the first inequality, we can add 6 to both sides: −27 > −3x. Then, we can divide both sides by -3, remembering to flip the inequality sign since we are dividing by a negative number: x > 9.5.
To simplify the second inequality, we can add 6 to both sides: −3x ≥ 0. Then, we can divide both sides by -3, remembering to flip the inequality sign: x ≤ 0.
Therefore, an equivalent form of the compound inequality −33 > −3x − 6 ≥ −6 is x > 9.5 or x ≤ 0.
Determine whether the formula describes y as a function of x. Explain your reasoning.y = -x
Answer:
Yes, [tex]y=-x[/tex] describes "y" as a funcion of "x", because each input value (value of "x") has only one ouput value (value of "y").
Step-by-step explanation:
By definition, a relation is a function if each input value (value of "x")has only one ouput value (value of "y").
We need to remember that "y as a function of x" means that "x" is the independent variable and "y" is the dependent variable or, in other words, the value of the variable "y" depends upon the value of the variable "x".
Then, [tex]y=-x[/tex] is a function, because each input value has one and only one output value. For example:
If [tex]x=-2[/tex], then:
[tex]y=-(-2)=2[/tex]
If [tex]x=1[/tex], then:
[tex]y=-(1)=-1[/tex]
If [tex]x=5[/tex], then:
[tex]y=-(5)=-5[/tex]
Therefore, [tex]y=-x[/tex] describes "y" as a funcion of "x".
Classify the following triangle
Answer:
Isosceles and obtuse
Step-by-step explanation:
It is not a scalene triangle because it has two same lengths 41 degrees and 41 degrees.
It is a Isosceles triangle because two of the sides have the same lengths 41 degrees and 41 degrees
It is an obtuse triangle because it has on obtuse angle which is 98 and two acute angles that are 41 degrees
It is not an equilateral because not all of the sides are the same lengths
It is not a right triangle because there are 90 degree angles
It is not an acute triangle because not all the angles are acute angles
A triangle can be classified based on its angles and sides. A Trigonal Bipyramidal triangle has angles of 90 degrees or 120 degrees, and atoms can be positioned equatorially (in the plane of the triangle) or axially (above or below the plane). Always remember that the sum of all interior angles of a triangle is 180°.
Explanation:The classification of a triangle depends on its angles and sides. If you have a triangle like a Trigonal Bipyramidal, the angles of such a triangle can be 90 degrees or 120 degrees. This relates to a three-dimensional trigonal bipyramidal molecular geometry where three atoms or groups of atoms are positioned in a flat triangle around a central atom, symmetrically positioned with 120° angles between each pair.
Another element you mentioned is the position of an attached atom in a triangle. This can be either equatorial (in the plane of the triangle) or axial (above or below that plane).
For detailed classification, always keep in mind that the sum of all interior angles of a triangle is always 180°. A triangle with one angle measuring 90° is a right triangle. An equilateral triangle has all angles measuring 60°. In the trigonal planar case, all atoms are in one plane, and bond angles are 120°.

Explain how you can use equivalent fractions to find the quotient of 2 3 ÷ 4.
Answer:
see below
Step-by-step explanation:
2/3 ÷ 4
We use copy dot flip
The flip means make a reciprocal of the second number
2/3 * 1/4
Multiply the numerators
2*1 = 2
Multiply the denominators
3*4 =12
Put the numerator over the denominator
2/12
Simplify
1/6
To use equivalent fractions to find the quotient of \( \frac{2}{3} \) ÷ 4, follow these steps:
### Step 1: Understand the Operation
Division of fractions can be thought of as multiplying by the reciprocal. The reciprocal of a number a is simply \( \frac{1}{a} \).
### Step 2: Find the Reciprocal of the Divisor
The divisor here is the whole number 4. Its reciprocal is \( \frac{1}{4} \).
### Step 3: Multiply the Dividend by the Reciprocal of the Divisor
Instead of dividing \( \frac{2}{3} \) by 4, you can multiply \( \frac{2}{3} \) by \( \frac{1}{4} \).
### Step 4: Perform the Multiplication
Now, multiply the two fractions:
\[ \frac{2}{3} \times \frac{1}{4} = \frac{2 \cdot 1}{3 \cdot 4} \]
This results in a new fraction:
\[ \frac{2}{12} \]
### Step 5: Simplify the Resulting Fraction
Finally, you need to simplify the fraction to its simplest form. To do that, find the greatest common factor (GCF) of the numerator and the denominator and divide both by this number.
For \( \frac{2}{12} \), the greatest common factor is 2. So we divide both the numerator and the denominator by 2:
\[ \frac{2 \div 2}{12 \div 2} = \frac{1}{6} \]
### Conclusion
Therefore, the quotient of \( \frac{2}{3} \) ÷ 4 is \( \frac{1}{6} \). This is the simplest form of the fraction you obtain when \( \frac{2}{3} \) is divided by 4.

Domain means all the x - values included in a set of data:
{(3, 5), (8, 6), (2, 1), (8, 6)}
It is unnecessary to put two of the same numbers. You only need to put one.
{2, 3, 8}
Hope this helped!
~Just a girl in love with Shawn Mendes
Answer: Last option.
Step-by-step explanation:
By definition, the Domain is the set of all the x-coordinates of the ordered pairs (input values) and the Range is the set of all the y-coordinates of the ordered pairs (output values)
In this case you have the following relation:
[tex]R:[/tex]{[tex](3, 5), (8, 6), (2, 1), (8, 6)[/tex]}
You can identify that the set of all the x-coordinates is:
{[tex]3,8,2,8[/tex]}
You can observe that the input value 8 appears twice, but you only need to write it once.
Therefore, the Domain of that relation is:
[tex]Domain:[/tex]{[tex]2,3,8[/tex]}
A die is rolled. What is the probability of rolling the following? A multiple of 3 or a multiple of 4
Answer:
1) 33.33%
2) 16.66%
Step-by-step explanation:
1) Since multiples of 3 in 1,2,3,4,5,6 include and limited to 3 and 6. This means that 2 / 6 or 1 / 3. This fraction is equal to 33.33%.
2) Since multiples of 4 in 1,2,3,4,5,6 include and limited to only 4. This means that 1/6 and this fraction is equal to 16.66%.
Answer:
1/2.
Step-by-step explanation:
A multiple of 3 is 3 or 6 and a multiple of 4 is 4.
Probability(3 or 6) = 2/6 = 1/3.
Probability(4 ) = 1/6.
So Probability ( multiple of 3 or a multiple of 4) = 1/6 + 1/3
= 1/2.

--------------------------------------------------------------------
cos(120 - x) = cos120cosx + sin120sinx
= -cos60cosx + sin60sinx
= - [tex]\frac{1}{2}[/tex]cosx + [tex]\frac{\sqrt{3} }{2}[/tex]sinx
squaring to obtain cos²(120 - x)
= [tex]\frac{1}{4}[/tex]cos²x - [tex]\frac{\sqrt{3} }{2}[/tex]sinxcosx + [tex]\frac{3}{4}[/tex]sin²x

The sum of two numbers is 86, and their difference is 20. Find the two numbers
Answer:
x = 53, y = 33
Step-by-step explanation:
Let one of the numbers = x, & the other = y. Set the equations:
x + y = 86
x - y = 20
This is a system of equation, in which the variables must be true for both of them.
First, choose a equation to use. In this case, I will choose x + y = 86. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract y from both sides.
x + y = 86
x + y (-y) = 86 (-y)
x = 86 - y
Now, note the other equation: x - y = 20. You now know that x = 86 - y. Plug in 86 - y for x in the "other" equation:
x - y = 20
(86 - y) - y = 20
Simplify. Combine like terms:
86 - y - y = 20
86 - 2y = 20
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction):
First, subtract 86 from both sides:
86 (-86) - 2y = 20 (-86)
-2y = 20 - 86
-2y = -66
Isolate the variable, y. Divide -2 from both sides:
(-2y)/-2 = (-66)/-2
Note: Before we go any further, I want to remind you of division & multiplication rules. There are 3 kinds, when you are multiplying two positive numbers (+/+), when you are multiplying a positive number with a negative number (+/-), and when you are multiplying a two negative numbers (-/-). Note the "table" in the bottom:
________________________________________________________
(+/+) : Two positive numbers multiplied/divided with each other will always result in a positive answer:
Examples:
10/5 = 2
20/10 = 2
(+/-) : One positive number and one negative number multiplied/divided with each other will always result in a negative answer:
Examples:
20 x -5 = -100
50 x -3 = -150
(-/-) : Two negative numbers multiplied/divided with each other will always result in a positive answer:
Examples:
-30 x -5 = 150
-200/-10 = 20
________________________________________________________
Now, solve the equation:
(-2y)/-2 = (-66)/-2
y = -66/-2
Divide.
y = 33
One of your numbers (y) is 33. Plug in 33 for y in one of the equations:
x + y = 86
x + (33) = 86
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 33 from both sides.
x + 33 (-33) = 86 (-33)
x = 86 - 33
x = 53
Your answers: x = 53, y = 33.
Check: Plug in 53 for x, 33 for y in the equations:
x + y = 86:
(53) + (33) = 86
86 = 86 (True)
x - y = 20:
(53) - (33) = 20
20 = 20 (True)
Your answers: x = 53, y = 33

f(x)=(x-2)^2-3
graph the parabola by first plotting its vertex and then plotting a second point on the parabola
Answer:
Step-by-step explanation:
Simply by comparing the given
f(x)=(x-2)^2-3 to
f(x) = (x-h)^2 + k, we see that h = 2 and k = -3, which tells us that the vertex of the graph is (2, -3). This parabola opens up because the coefficient of (x-2)^2 is +1.
Evaluating f(x)=(x-2)^2-3 at x = 4 (an arbitrary value), we see that
f(4) = (4-2)^2 - 3 = 4 - 3 = 1.
The point (4, 1) is also on the graph of this parabola.
Graph the vertex (2, -3) and the arbitrarily chosen point (4, 1). Remember that (2, -3) is the minimum of this function, so for x other than 2, the y-value is greater than -3.

Zahra wants the equation below to have an infinite number of solutions when the missing number is placed in the box.
Answer:
box contains - 3
Step-by-step explanation:
a(x - 3) + 2x = -(x - 5) +4 Remove the brackets on both sides
ax - 3a + 2x = -x + 5 + 4 Subtract 2x from both sides.
ax - 3a + 2x - 2x = -x - 2x + 9
ax - 3a = - 3x + 9
ax - 3(-3) = - 3x + 9
ax + 9 = - 3x + 9
Now if you make a = -3 then both sides with have - 3 for the x coefficient.
Any number could be put in for x and it will make the answer on both sides equal. Notice you could subtract 9 from both sides and it will not change the condition of the problem.
Answer:
c = -3
Step-by-step explanation:
Call the unknown c
c(x-3) +2x = -(x-5) +4
Distribute the negative sign
c(x-3) +2x = -x+5+4
Combine like terms
c(x-3) +2x = -x +9
Subtract 2x from each side
c(x-3) +2x-2x = -x-2x +9
c(x-3) = -3x+9
Factor a -3 from the right side
c(x-3) = -3(x-3)
Divide by (x-3)
c = -3
The right and left hand side need to be equal for there to be infinite solutions, so c = -3

A polynomial function can be written as (x − 1)(x − 4)(x + 7). What are the x-intercepts of the graph of this function? (4 points) (1, 0), (4, 0), (7, 0) (−1, 0), (−4, 0), (−7, 0) (1, 0), (4, 0), (−7, 0) (−1, 0), (−4, 0), (7, 0)
Answer:
Option C is correct.
Step-by-step explanation:
The x-intercepts of the function (x − 1)(x − 4)(x + 7) can be found by putting this function equal to zero
(x − 1)(x − 4)(x + 7) = 0
Now,
x-1 = 0
x-4 = 0
and x+7 = 0
Now finding the values of x
x-1 = 0 + 1
x - 1 + 1 = 1
=> x = 1
or (1,0)
x - 4 = 0
x -4 + 4 = 0 + 4
x = 4
or (4,0)
x + 7 = 0
x +7 -7 = 0 -7
x = -7
or (-7,0)
SO, the x-intercepts of the function (x − 1)(x − 4)(x + 7) are (1,0),(4,0) and (-7,0)
Option C is correct.
Answer:
+ 1 + 4 -7
Step-by-step explanation:
when they ask for x intercepts you simply have to set the function to 0 and then solve for x or in other words just reverse the number for example. here we have -1 -4 and +7 so just reverse the negative and positive signs

a. I=5350E +37100
b. I=5350E-37100
c. I=5350E
d. E=5350E+37100
Answer:
a. I=5350E +37100
Step-by-step explanation:
The trend line does not start at the origin so we can immediately rule out option C
The equation should be in slope intercept form so we can rule out option D, since E is the x axis and we are looking for y = mx + b not x = mx + b.
Option B is ruled out because if we plug in the value of E = 2 then we get:
I = 5350(2) - 37100
I = 10700 - 37100
I = -16400
Which is wrong since we are not in the negative so your answer is A

what is the probability of rolling a 6 sided die and getting a 1 or a prime number
Answer:
P = 4 / 6 = 2/3 = 0.66 = 66%
Step-by-step explanation:
Assuming the die is numbered 1 to 6.
To answer the question, we first need to know many prime numbers can be represented on the die. What are the prime numbers equal to 6 or lower?
We have 2, 3 and 5. (since 4 and 6 are not prime numbers). So we have 3 prime numbers, plus the number 1... so there are 4 possibilities valid for rolling a 1 or a prime number: 1,2,3 and 5.
4 possibilities out of 6 total possible outcomes, so...
P = 4 / 6 = 2/3 = 0.66 = 66%
Answer:
The probability of rolling a 6 sided die and getting a 1 or a prime number = 2/3
Step-by-step explanation:
The numbers on the die are 1, 2, 3, 4, 5 and 6
To find the probability
Total outcomes of rolling a die = 6
Prime numbers less than 6 are 2, 3 and 5
Possible outcomes(getting 1 or a prime number) = 1, 2, 3 and 5
Probability of getting 1 or prime number when rolling a die = 4/6 = 2/3
Given ƒ(x) = 7x + 1 and g(x) = x^2, find (g ○ ƒ)(x)
For this case we have the following functions:
[tex]f (x) = 7x + 1\\g (x) = x ^ 2[/tex]
We must find[tex](g_ {0} f) (x).[/tex]
By definition of composition of functions we have to:
[tex](g_ {0} f) (x) = g (f (x))[/tex]
So:
[tex](g_ {0} f) (x) = g (f (x)) = (7x + 1) ^ 2 = 49x ^ 2 + 2 (7x) (1) + 1 = 49x ^ 2 + 14x + 1[/tex]
ANswer:
[tex](7x + 1) ^ 2 = 49x ^ 2 + 14x + 1[/tex]
two parallel lines are crossed by a transversal what is the value of b
Answer:
b=128
Step-by-step explanation:
Answer:
Option D b = 128°
Step-by-step explanation:
There are two parallel lines p and q
These lines are crossed by a transversal m
then ∠b and ∠128° are the alternate angles.
which should be equal in measure.
Therefore, ∠b = 128°
Option D b = 128° is the answer.
The table below relates the number of rats in a population to time in weeks. Use the table to write a linear equation with w as the input variable.
P(w)=
Answer:
C(w) = 6w + 9
Step-by-step explanation:
Anytime 0 is given somewhere, it should be given close scrutiny. In an equation whose general form is
y = mx + b
0 will determine the y intercept immediately.
So when x = 0, y will equal
y = 0*m + 9
So b = 9
y = mx + 9 Now we need to find m
I should start using your variables.
C(w) = m*w + 9
when w = 3 then C(3) = 27
27= 3m +9
27-9 =3m + 9 -9
18 = 3m
18/3 = 3m/3
x = 6
So the complete equation is
C(w) = 6w + 9
Answer:
[tex]P(w)=6w+9[/tex]
Step-by-step explanation:
To find the linear equation, first we need to calculate the slope of that line, we is defined as
[tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
Where we need to use two points from the table: (0,9) and (4,33).
Replacing these points, we have
[tex]m=\frac{33-9}{4-0}=\frac{24}{4} =6[/tex]
Now, we use the point-slope formula to find the equation
[tex]y-y_{1} =m(x-x_{1} )\\y-9=6(x-0)\\y=6x+9[/tex]
Let's call [tex]y=P(w)[/tex] and [tex]x=w[/tex].
The equation that models the given table is
[tex]P(w)=6w+9[/tex]
