Answer:

Step-by-step explanation:

Corresponding angles equal 180 degrees when added

6x + 3x = 180

9x = 180

x = 20

angle CBD is 60 and angle GFH is 120

3(20) = 60

If F(x) = +4, which of the following is the inverse of Fx)?
Viefleur [7K]

Answer:

f^{-1} = \frac{ 7(x-4)}{2}

Step-by-step explanation:

Given

f(x) = \frac{2x}{7} + 4

Required

The inverse function

f(x) = \frac{2x}{7} + 4

Replace f(x) with y

y = \frac{2x}{7} + 4

Swap x and y

x = \frac{2y}{7} + 4

Multiply through by 7

7x = 2y + 28

Solve for 2y

2y = 7x - 28

Solve for y

y = \frac{ 7x-28}{2}

Factorize

y = \frac{ 7(x-4)}{2}

Write as:

f^{-1} = \frac{ 7(x-4)}{2}
