The first thing you would do is switch the x and y (B).

For example, to find the inverse of y = 2x + 8:

1. Swap x and y
    x = 2y + 8

2. Solve for y (set the equation equal to it):
    x - 8 = 2y
    y = (x - 8) ÷ 2
    f^{-1}(x) = 1/2x - 4

A rectangular carpet has a perimeter of 194 inches. The length of the carpet is 67 inches more than the width. What are the dime
sammy [17]

Answer:

The dimensions of the carpet are 15 inches and 82 inches

Step-by-step explanation:

Assume that the width of the carpet is x inches

∵ The width of the carpet is x inches

∵ The length of the carpet is 67 inches more than the width

∴ The length of the carpet is (x + 67) inches

∵ The perimeter of the rectangle = 2(length + width)

∵ The perimeter of the carpet = 194 inches

→ Equate the two right sides of the perimeter

∴ 2(length + width) = 194

→ Divide both sides by 2

∴ length + width = 97

→ Substitute the value of the length and width in the equation above

∵ x + 67 + x = 97

→ Add the like terms in the left side

∴ (x + x) + 67 = 97

∴ 2x + 67 = 97

→ Subtract 67 from both sides

∵ 2x + 67 - 67 = 97 - 67

∴ 2x = 30

→ Divide both sides by 2

∴ x = 15

∵ x represents the width of the carpet

∴ The width of the carpet is 15 inches

∵ The length of the carpet = 15 + 67

∴ The length of the carpet is 82 inches

∴ The dimensions of the carpet are 15 inches and 82 inches

How would you solve this
Ber [7]
From what I can see with this picture, it seems like theyre asking for percentages of one number, to take a percentage of a number you convert the percent to a decimal, so 10% is equal to 10/100 = .10, so 200 * .10 = 20
