The length of a rectangle is given by L=3y + 4x while the width is

Wittaler [7]

Answer:

21y² +34 yx + 8x²

Step-by-step explanation:

Area of a rectangle is given by L×W where L is length, and W is width

Given L=3y+4x

W=7y+2x

Area= (3y+4x) × (7y+2x)

3y(7y+2x) + 4x(7y+2x)

21y² + 6yx +28yx+8x²

21y² +34 yx + 8x²

Which represents the inverse of the function f(x) = 4x?

kondor19780726 [428]

Answer:

Step-by-step explanation:

(1) = f(x) = 4x

$y = 4x\\x = 4y\\y = \frac{x}{4}\\f^{-1}(x) = \frac{x}{4}$

(2) h(x) = x + 4

y = x + 4

Replace x with y and vice versa:

x = y + 4

And then solve for 'y':

y = x - 4

$h^{-1}(x) = x - 4$

(3) h(x) = x - 4

y = x - 4

x = y - 4

y = x + 4

$h^{-1}(x) = x + 4$

(4) h(x) = 2x

y = 2x

x = 2y

y = $\frac{x}{2}$

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