Answer:
C
Step-by-step explanation:
looking at the graph, we see a parabola shifted up 6 units. the function is f(x) = x² + 6
we also see a line with a reflection on the y axis and a vertical shift up 6 units. the function is f(x) = -x + 6
x² + 6 is graphed like a normal parabola (u shaped graph) with an open circle on (3,15). the x coordinate is whats important here, which is 3. we see that there are no values to the right of 3, and only to the left of 3. we can say that the statement x < 3 is true of the parabola, as any value less than 3 is a solution to the parabola.
for -x + 6, we see a line graphed with an closed circle on approximately (3,3). again, the x-coordinate is important here which is 3. the line only goes to the right of 3, meaning the inequality x ≥ 3 is true of the line as any value greater than or equal to 3 is a solution
looking at our answer choices we need to find the following answer:
x² + 6 x < 3 and -x + 6 x ≥ 3
this answer would be C

Greg’s gas tank is 1/3 full after he buys 2 gallons of gas it is 1/2 full how many gallons can Greg’s tank hold
Answers
Answer:
12 gallons
Step-by-step explanation:
let x be the amount tank can hold, then
[tex]\frac{1}{3}[/tex] x + 2 = [tex]\frac{1}{2}[/tex] x
Multiply through by 6
2x + 12 = 3x ( subtract 2x from both sides )
12 = x
The tank can hold 12 gallons
Greg's gas tank can hold 12 gallons of gas. We know this because when Greg's tank is 1/3 full and he buys 2 gallons of gas it becomes 1/2 full. The difference between 1/2 and 1/3 of a tank, or 1/6 of the tank, is equal to 2 gallons.
Explanation:
The subject of this question is mathematics, specifically within the scope of fractions and simple algebra. The question tells us that when Greg's gas tank is 1/3 full and he adds 2 gallons, the tank becomes 1/2 full. This tells us that the difference between 1/2 and 1/3 of the tank's capacity is equal to 2 gallons. In mathematical terms, this can be represented as 1/2 - 1/3 = 2/6 - 2/6 = 1/6. Therefore, 1/6 of Greg's gas tank equals 2 gallons. If 1/6 of the tank equals 2 gallons, the entire tank (or 6/6) would hold 12 gallons of gasoline.

Find f(-3) for f(x) = 4(2)^x
Answers
Hey there! :D
f(-3)= 4(2)^x
Just plug in -3 as x and solve.
4(2)^-3
First do the exponent, and then multiply the four on the outside.
4(1/8)
=1/2
I hope this helps!
~kaikers
Final answer:
To calculate f(-3) for the function f(x) = 4(2)ˣ, substitute -3 into the function, yielding f(-3) = 1/2 after simplifying 4 times 2 raised to the power of -3.
Explanation:
To find f(-3) for the function f(x) = 4(2)ˣ, simply substitute -3 for x in the equation. Here's How:
Start with the original function f(x) = 4(2)ˣ.
Replace every x with -3 to get f(-3) = 4(2)⁻³.
Calculate 2⁻³, which equals 1/8 because negative exponents represent the reciprocal of the base raised to the positive exponent.
Now, multiply 4 by 1/8 to get f(-3) = 4 * 1/8 = 1/2.
Therefore, f(3) for the given function equals 1/2.
If two distinct lines intersect, which is NOT necessarily true? A) The lines are not parallel. B) The lines are perpendicular. C) The lines form angles at the intersection. D) The intersection of the two lines is a point.
Answers
Answer:
B is not necessarily true
Step-by-step explanation:
A) This is always true
B) This is not necessarily true
When two lines intersect, they form angles at the intersection as D says, but that does not mean that the angle will always be 90 degrees as is required for the two intersecting lines to be perpendicular
C) This is always true
D) This is always true
Option B) The lines are not perpendicular is not necessarily true.
What is the Intersection of Two lines?When two lines intersect and following are the three different possibilities:
1) They are parallel, if lines are parallel they can never intersect.
2)They cross each at an angle and the point of intersection is unique that is they intersect at only one point.
3) Two lines coincide, that is every point on line 1 is a point on line 2.
Now
In option B it is given that lines are perpendicular that is the specific case of (2) When angle is 90°.
Therefore, it is not necessarily true.

[tex]y = 3 \pm \sqrt{21} [/tex]
EXPLANATION
The quadratic equation is:
[tex] {y}^{2} - 6y - 12 = 0[/tex]
Group variable terms:
[tex] {y}^{2} - 6y = 12[/tex]
Add the square of half, the coefficient of y to both sides.
[tex] {y}^{2} - 6y + ( - 3) ^{2} = 12 + ( - 3) ^{2} [/tex]
[tex] {y}^{2} - 6y + 9= 12 + 9[/tex]
The LHS us now a perfect square trinomial:
[tex]{(y - 3)}^{2}= 21[/tex]
Take square root:
[tex]y - 3 = \pm \sqrt{21} [/tex]
[tex]y = 3 \pm \sqrt{21} [/tex]
The first choice is correct.
3±√21. The equation [tex]y^{2}-6y-12=0[/tex] has two possible solutions 3+√21 y 3-√21.
If we have a general quadratic equation [tex]ay^{2} +by+c=0[/tex] we can solves the equation by completing the square. First, we divide the quadratic equation by a, we obtain [tex]y^{2} +\frac{b}{a} y+\frac{c}{a} =0[/tex].
For this problem, we have [tex]y^{2}-6y-12=0[/tex]
We can skipped division in this example since the coefficient of [tex]x^{2}[/tex] is 1.
Move the term c to the right side of the equation
[tex]y^{2}-6y=12[/tex]
Completing the square on the left side of the equation and balance this by adding the same number to the right side of the equation, with b = -6.
[tex](\frac{b}{2})^{2} =(\frac{-6}{2})^{2}=(-3)^{2} =9[/tex]
[tex]y^{2}-6y+9=12+9[/tex]

Answer:
4x + y = 32
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
First obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 4) and (x₂, y₂ ) = (5, 12)
m = [tex]\frac{12-4}{5-7}[/tex] = [tex]\frac{8}{-2}[/tex] = - 4, thus
y = - 4x + c ← is the partial equation of the line
To find c substitute either of the 2 points into the partial equation.
Using (7, 4), then
4 = - 28 + c ⇒ c = 4 + 28 = 32
y = - 4x + 32 ← in slope- intercept form
Add 4x to both sides
4x + y = 32 ← in standard form

Hey there!
If we have two white marbles and seven purple marbles, our first probability is out of nine.
First of all, we have the probability of selecting a purple marble, 7/9.
Now, if we do not replace it, there are only eight marbles left. Therefore, getting a white marble is 2/8, or 1/4.
We multiply these probabilities together to get our answer to a.
7/9(1/4)= 7/36
a. 7/36
Now, let's do b. We have 2/9, and then 1/8, giving us 1/36.
b. 1/36
Now, let's calculate selecting two purple to help us with C.
We have 7/9, and then 6/8, or 3/4.
7/9(3/4)= 7/12
Since there is a majority of purple marbles, there is a C) greater probability of selecting two purple marbles in a row.

The missing words
# x ⇒ # y ⇒ # 4 ⇒ # 0
Step-by-step explanation:
* Lets revise how to find the inverse function
- At first write the function as y = f(x)
- Then switch x and y
- Then solve for y
- The domain of f(x) will be the range of f^-1(x)
- The range of f(x) will be the domain of f^-1(x)
* Now lets solve the problem
∵ f(x) = √(x - 4)
∴ y = √(x - 4) ⇒ switch x and y
∴ x = √(y - 4) ⇒ square the two sides
∴ x² = [√(y - 4)]² ⇒ cancel the root by squaring
∴ x² = y - 4 ⇒ add 4 to the both sides
∴ y = x² + 4
∴ f^-1(x) = x² + 4
* To find the domain of the inverse, find the range of the function
∵ The domain of f(x) is ⇒ x - 4 ≥ 0 (no negative value under√)
∴ the domain is x ≥ 4
- Substitute this value in the function to find the range
∵ x = 4
∴ y = √(4 - 4) = 0
∴ y ≥ 0
- The range of f(x) is y ≥ 0
∴ The domain of the inverse f^-1(x) is x ≥ 0

After 3 months 5004 deposited in a savings account with simple interest had earned 162.63 in interest. What was the interest rate
Answers
Answer:
13%
Step-by-step explanation:
Please use the $ sign.
The simple interest formula is i = p*r*t, where p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years. Here, t = 1/4 year; r is unknown, p is $5004 and i is $162.63.
Writing this out with the given info, we get:
$162.63 = $5004*r*(1/4).
We can solve this for r by multiplying both sides by 4/$5004:
(4/$5004)($162.63) = (4/$5004)($5004)*r*(1/4) = r
Evaluating r, we get (4)($162.63)/$5004 = 0.13
The interest rate, r, is 0.13, or 13%.

Answers
Answer:
Step-by-step explanation:
Without a second equation relating x and y, we can solve 3x - 1/2y = 2 ONLY for x in terms of y or for y in terms of x:
x in terms of y: Multiply all three terms of 3x - 1/2y = 2 by 2, to eliminate the fraction: 6x - y = 4. Now add y to both sides to isolate 6x: 6x = 4 + y.
Last, divide both sides by 6 to isolate x:
x = (4 + y)/6
y in terms of x:
y = 6x - 4
