a line passes through the points -3 -4 and 6 2 what is the Y intercept of this line? -3 -2 2 or 3
Answer:
y=-2
Step-by-step explanation:
Hello : let A(-3,-4) B(6,2)
the slope is : (YB - YA)/(XB -XA)
(2+4)/(6+3) = 6/9 = 2/3
an equation is the line is : y = ax+b a is a slope
y = (2/3)x+b
but this line passes by (6;2)
so : 2 = (2/3)(6)+b
b = -2
the equation is : y = (2/3)x-2
the the Y intercept of this line when : x= 0 so : y = (2/3)(0)-2
y=-2

[tex]y = \pm\sqrt{x}[/tex]
==================================================
Explanation:
The plus/minus indicates we have two equations, and they are
[tex]y = \sqrt{x} \text{ or } y = -\sqrt{x}[/tex]
If x is say x = 4, then y is both y = 2 and y = -2 at the same time.
A function is where any x input leads to exactly one and only one y output (assuming the x value is in the domain). Graphing out choice D shows that it fails the vertical line test. This is where a vertical line crosses through more than one point on the graph. For the other answer choices, it is impossible to draw a vertical line through more than one point on the graph, which visually shows they are functions.
Expand the polynomial: (6x^2−11y^3)(−6x^2−11y^3)

Step-by-step explanation:
We have , (6x^2−11y^3)(−6x^2−11y^3):
[tex](6x^2-11y^3)(-6x^2-11y^3)[/tex]
⇒ [tex](6x^2-11y^3)(-6x^2-11y^3)[/tex]
We know that :

⇒ [tex](6x^2(-6x^2) - 11y^3(-6x^2) )+(6x^2(-11y^3) + (-11y^3)(-11y^3))[/tex]
⇒ [tex](-36x^4+66x^2y^3 -66x^2y^3 + 121y^6)[/tex]
⇒ [tex](-36x^4+ 121y^6)[/tex]
⇒ [tex]121y^6 -36x^4[/tex]
Therefore, on expanding polynomial (6x^2−11y^3)(−6x^2−11y^3) or [tex](6x^2-11y^3)(-6x^2-11y^3)[/tex] is [tex]121y^6 -36x^4[/tex] .
chords ac and bd intercept at e if ae=6 ec=12 and dc=18 how long is be
Option A:
The length of BE is 4.
Solution:
Given data:
AE = 6, EC = 12 and DE = 18
To find the length of BE:
If two chords intersect in a circle, then the product of lengths of one segment is equal to the product of lengths of other segment.
⇒ AE × EC = DE × BE
⇒ 6 × 12 = 18 × BE
⇒ 72 = 18 × BE
Divide by 18 on both sides of the equation.
⇒ 4 = BE
Switch the sides.
⇒ BE = 4
The length of BE is 4.
Option A is the correct answer.

The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.
Step-by-step explanation:
Step 1:
To determine if the function represents growth or decay, we substitute values to x.
If the values increase with an increase of x, it represents growth.
If the values decrease with an increase of x, it represents decay.
Step 2:
If [tex]x= 10,[/tex] [tex]y = 1,300 (\frac{1}{2})^{\frac{10}{69} } = 1,300 (0.9044) = 1,175.72.[/tex]
If [tex]x=11,[/tex][tex]y = 1,300 (\frac{1}{2})^{\frac{11}{69} } = 1,300 (0.8953) = 1,163.89.[/tex]
So as x increases the value of y decreases, so it represents decay.
Step 3:
The percentage rate of change is determined by dividing the difference of two consecutive values by the first value.
The percentage rate of change [tex]= \frac{y(x=11) - y(x=10)}{y(x=10)}.[/tex]
Substituting the values, we get
The percentage rate of change [tex]=\frac{1,175.72-1,163.89}{1,175.72}(100) = 1.00619\%[/tex].
As the values of y decrease with an increase in x, it is the percent decrease per unit.
Answer:
The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.

Use the distributive property to solve : 20 (30 - 15) =
Answer:
the distribute property is basically taking the number outside the parenthesis and multiplying with the numbers inside each by each.
Step-by-step explanation:
20(30-15)
20×30= 600, and 20×15=300
finally you just use the new numbers and solve the solution which is 600-300. The answer is 300
Answer: 300
Step-by-step explanation: The distributive property tells us that when there's a number outside a set of parentheses, you can multiply it times each of the terms that are inside the set of parentheses and then add those products together.
So in this problem, we can multiply 20 (30) - 20 (15) which simplifies to 600 - 300 which is 300.
Amira has 3/4 of a bag of cat food. Her cat eats 1/10 of a bag per week. How many weeks will the food last.
Answer:15
Step-by-step explanation:
You have to divide the fractions so it 3/4÷1/10 then you can do keep change flip so the new equation is 3/4×10/1 or 3/4×10 then cross simply then get 3/2×5/1 to get 15/2 then use division to get 7 1/2
Amira's cat food will last 7.5 weeks, considering the cat eats 1/10 of a bag per week.
To find out how many weeks the cat food will last, you can divide the amount of food Amira has by the amount her cat eats per week.
First, let's calculate how much her cat eats per week:
1/10 of a bag per week.
Now, let's calculate how many weeks the food will last:
(3/4) / (1/10)
To divide fractions, you can multiply by the reciprocal of the divisor:
(3/4) * (10/1) = (3/4) * 10 = (3 * 10) / 4 = 30/4
Now, let's simplify 30/4:
30 divided by 4 equals 7 with a remainder of 2, so 30/4 = 7 + 2/4
Since 2/4 simplifies to 1/2, we get:
7 + 1/2 = 7.5
So, the cat food will last approximately 7.5 weeks.

In an office building, an elevator has a maximum carrying capacity of 2,700 pounds. Based on the average weight (180 pounds male) (150 pounds female) how many males and females can fit on the elevator.
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> the number of males on the elevator
y ----> the number of females on the elevator
we know that
The inequality that represent this situation is
[tex]180x+150y\leq 2,700[/tex]
The solution of the inequality is the shaded area below the solid line [tex]180x+150y=2,700[/tex]
The slope of the solid line is negative
The y-intercept of the solid line is (0,18)
The x-intercept of the solid line is (15,0)
see the attached figure
The solution is the triangular shaded area
The maximum number of females is 18 (when the number of males is zero)
The maximum number of males is 15 (when the number of females is zero)

H(y)=9/5 • 2y at y=-2
Answer:
[tex]H( - 2) = - 7 \frac{1}{5} [/tex]
Step-by-step explanation:
We want to evaluate the equation
[tex]H(y) = \frac{9}{5} \times 2y[/tex]
at y=-2
We just have to substitute to obtain;
[tex]H( - 2) = \frac{9}{5} \times 2 \times - 2[/tex]
We now multiply to get:
[tex]H( - 2) = \frac{9}{5} \times - 4[/tex]
This is the same as:
[tex]H( - 2) = \frac{9}{5} \times \frac{ - 4}{1} [/tex]
We multiply the numerators separately and denominators separately to get:
[tex]H( - 2) = \frac{9 \times - 4}{5 \times 1} [/tex]
[tex]H( - 2) = \frac{ - 36}{5} [/tex]
This implies that
[tex]H( - 2) = - 7 \frac{1}{5} [/tex]

x = 37
(x + 15)
(4x - 20°
x = 40
Answer:
Option D, x = 40
Step-by-step explanation:
Since x and (4x - 20) are supplementary, that means they add up to 180 degrees.
Step 1: Make an equation
x + (4x - 20) = 180
Step 2: Combine like terms
x + 4x - 20 = 180
5x - 20 = 180
Step 3: Add 20 to both sides
5x - 20 + 20 = 180 + 20
5x = 200
Step 4: Divide both sides by 5
5x / 5 = 200 / 5
x = 40

If twice a number, n, is 5 less than the number squared, which of the following equations could be used to properly solve for n?
Answer:
2n - 5 = n^2 (or n squared)
The equation that could be used to properly solve for n is [tex]n^2 - 2n - 5 = 0[/tex]
Mathematical equationsTo properly solve for the number, n, based on the given information, you can use the equation:
[tex]2n = n^2 - 5[/tex]
This equation represents the statement "Twice a number, n, is 5 less than the number squared." It sets the twice of the number (2n) equal to the number squared minus 5 (n^2 - 5).
To solve for n, you can rearrange the equation as follows:
[tex]n^2 - 2n - 5 = 0[/tex]
You can then solve this quadratic equation for n using methods such as factoring, completing the square, or the quadratic formula.

jenna brought a spool of ribbon that was 5 3/4 meters long. she used 3 1/4 meters of ribbon for a craft project. how many meters of ribbon does jenna have left?
Answer:
So the answer will be 2 2/4
Step-by-step explanation:
If you need me to explain more please tell me.Hope it helps.
Jenna is left with 2 1/2 meters of ribbon for future projects.
Jenna bought a spool of ribbon that was 5 3/4 meters long and used 3 1/4 meters of it for a craft project. To calculate how much ribbon she has left, we need to subtract the length of the ribbon used from the total length of the ribbon.
Convert mixed numbers into improper fractions: 5 3/4 = (5 × 4) + 3 = 23/4 and 3 1/4 = (3 × 4) + 1 = 13/4.
Subtract the second fraction from the first: 23/4 - 13/4 = (23 - 13)/4 = 10/4.
Simplify the result: 10/4 = 2 2/4 = 2 1/2 meters.

–2(g − 13) + 15 = 1
how do you do this
Answer:
3bzycukznwvy knsheuje6d9qk3vhdurkgyvuf6dyguts bl es yvhuv
Answer:
g = 20
Step-by-step explanation:
−2 (g − 13) + 15 = 1
Step 1: Simplify both sides of the equation.
−2 (g−13) + 15 = 1
(−2) (g) + (−2) (−13) + 15 = 1 (Distribute)
−2g + 26 + 15 = 1
(−2g) + (26 + 15) = 1 (Combine Like Terms)
−2g + 41 = 1
−2g + 41 = 1
Step 2: Subtract 41 from both sides.
−2g + 41 − 41 = 1 − 41
−2g = −40
Step 3: Divide both sides by -2.
−2g/−2 = −40/−2
g = 20
Which graph shows the solution to the system of linear inequalities below? y>2x+1 y<2x-3
Option D: Graph C is the solution to the system of linear inequalities.
Explanation:
The system of linear inequalities are [tex]y \geq 2 x+1[/tex] and [tex]y<-2 x-3[/tex]
Let us graph the inequality [tex]y \geq 2 x+1[/tex]
Let us substitute the coordinate [tex](0,0)[/tex] in the inequality [tex]y \geq 2 x+1[/tex], we get,
[tex]0 \geq 2 (0)+1[/tex]
[tex]0 \geq1[/tex]
This is false. Hence, the solution does not contain the coordinate [tex](0,0)[/tex]
Thus, let us shade the upper part of the line in the graph.
Similarly, let us substitute the coordinate [tex](0,0)[/tex] in the inequality [tex]y<-2 x-3[/tex], we get,
[tex]0<-2 (0)-3[/tex]
[tex]0<-3[/tex]
This is false. Hence, the solution does not contain the coordinate [tex](0,0)[/tex]
Thus, let us shade the lower part of the line in the graph.
The solution to the system of linear inequality is the intersection of the two regions.
Thus, the solution of the inequality is Graph C.
Hence, Option D is the correct answer.
