Answer:x=150

Step-by-step explanation:

Step 1: Subtract 1.2x from both sides.

0.8x+20−1.2x=1.2x−40−1.2x

−0.4x+20=−40

Step 2: Subtract 20 from both sides.

−0.4x+20−20=−40−20

−0.4x=−60

Step 3: Divide both sides by -0.4.

−0.4x

−0.4

−60

−0.4

If FX) = 3x+6, which of the following is the inverse of Fx)?

LenaWriter [7]

Answer:

C. F'(x) = x - 6 / 3

Step-by-step explanation:

$y = 3x + 6$

$x = 3y + 6 \\ x - 6 = 3y + 6 - 6$

$\frac{x - 6}{3} = \frac{3y}{3}$

$y = \frac{x - 6}{3}$

$f1 = \frac{x - 6}{3}$
