Which equation is the inverse of 2(x - 2)2 = 8(7 + y)?
Scrat [10]

The inverse of an equation is the opposite of the equation

The inverse of the function is y =2 \pm  \sqrt{28 + 4x

<h3>How to determine the inverse of the function </h3>

The equation is given as:

2(x - 2)^2 = 8(7 + y)

Divide both sides of the equation by 2

(x - 2)^2 = 4(7 + y)

Open the bracket

(x - 2)^2 = 28 + 4y

Take the square roots of both sides

x - 2 = \pm\sqrt{28 + 4y

Add 2 to both sides

x =2 \pm  \sqrt{28 + 4y

Swap the occurrences of x and y

y =2 \pm  \sqrt{28 + 4x

Hence, the inverse of the function is y =2 \pm  \sqrt{28 + 4x

Nancy joined a school band .she bought 4 violins at 87.82 per violin and 2 song books
tatiyna

Answer:

$32.80

Step-by-step explanation:

Find out how much Nancy spent on 4 violins and 2 song books.

1 violin = 87.82

4 violins = 87.82 x 4 = 351.28

1 song book = 7.96

2 song books = 7.96 x 2 = 15.92

351.28 + 15.92 = 367.20

4 x 100 dollar bills = 400 dollars

Normally after paying for an item, if you pay much more money than the actual price of the item, you'll get some money back from the cashier. That's called a change.

400 - 367.20 = 32.80
