F(x) = 3x + 2 replace f(x) with y
kirill [66]

Answer:

 -1           x - 2

f    (x) = -----------

                  3

Step-by-step explanation:

Then we have y = 3x + 2.

Next, interchange x and y, obtaining x = 3y + 2

Next, solve this result for y:  3y = x - 2; then divide both sides by 3:

y = (x-2)/3

Last, replace "y" with the inverse function label:

 -1           x - 2

f    (x) = -----------

                  3

Solve<br> for x:<br> 3(1 - 3x) = 2(-4x + 7)
djverab [1.8K]

Answer:

x= -11

Step-by-step explanation:

distribute the 3 and the 2:   3 - 9x = -8x + 14

add 9x from both sides and subtract 14 from both sides:  -11 = x

x = -11

Answer:

  373 miles

Step-by-step explanation:

The difference in latitude is ...

  39.1° -33.7° = 5.4° = 0.54°(π/180°) radians = 0.03π radians

The arc length is given by ...

  s = rθ, where θ is the angle in radians

The length of the arc along the longitude line is ...

  s = (3960 mi)(0.03π) ≈ 373 mi

The distance from Atlanta to Cincinnati is about 373 miles.
