Answer:

320 in²

Step-by-step explanation:

Given that Lin has a drawing that has an area of 20 in², since Lin used a scale factor of 4 to increase all sides, therefore the new area would be increased by the following:

Square of scale factor of the side = scale factor of area

4² = scale factor of area

16 = scale factor of area

Multiply the original area by 16

20 × 16 = 320 in²

Answer:

see explanation

Step-by-step explanation:

let y = f(x), then

y = 11x - 1

Interchange x and y and solve for y

x = 11y - 1 ( add 1 to both sides )

x + 1 = 11y ( divide both sides by 11 )

y = $\frac{x+1}{11}$ , hence

$f^{-1}$ (x) = $\frac{x+1}{11}$
