<h2><u>Inverse Variation</u></h2>

<h3>Q varies inversely with x. if q = 12 when x = 5, find the value of q when x = 12.</h3>

<em>q varies inversely as x: qx = k, such k is constant</em>

<u>Given values:</u>

q = 12
x = 5

To determine the constant of variation, substitute the first two given values of q and x to the equation of variation.

qx = k
(12)(5) = k
60 = k

To determine the value of q, substitute the second given value of x together with the constant of variation.

x = 12, q = ?
qx = 60
12q = 60
q = 60/12
q = 5

<u>Answer:</u>

The value of q is <u>5</u>.

Ivanshal [37]

Answer:

1/3 of the pizza remains.

Step-by-step explanation:

Matthew eats 1/3 of 1/2 of the pizza, which is (1/3)*(1/2) = 1/6 of the pizza. The amount of pizza left is

1/2 - 1/6 = 3/6 - 1/6 = 2/6 = 1/3

1/3 of the pizza remains.

Write a quadratic function in vertex form whose graph has the vertex (5,−2) and passes through the point (7,0).

Hatshy [7]

The quadratic function in vertex form is $y=\frac{1}{2} (x-5)^{2}-2$ .

Solution:

The equation of a quadratic in vertex form is $y=a(x-h)^{2}+k$ .

where (h, k) are the coordinates of the vertex and "a" is a multiplier.

Here (h, k) = (5, –2)

Substitute this in the vertex form.

$y=a(x-5)^{2}+(-2)$

$y=a(x-5)^{2}-2$ – – – – (1)

Passes through the point (7, 0).

Here x = 7 and y = 0.

Substitute this in equation (1), we get

$0=a(7-5)^{2}-2$

$0=4a-2$

Add 2 on both sides.

2 = 4a

Divide 2 on both sides, we get

$$a=\frac{1}{2}$

Substitute the value of a in equation (1),

$$y=\frac{1}{2} (x-5)^{2}-2$

The quadratic function in vertex form is $y=\frac{1}{2} (x-5)^{2}-2$ .

D is your answer

plug in the x value and y value to the equation

when x = 1, and y = 4
-1 + 4 = 3

when x = 5, and y = 8
-5 + 8 = 3

hope this helps :D
