Answer:

f^-1(x) = (x+2)/3

Step-by-step explanation:

F(x) = 3x-2

substitute x for y, and f(x) for x: x = 3y - 2

Solve for y: x + 2 = 3y

y = f^-1(x) = (x+2)/3

Answer:

$\displaystyle PW = \underline{ \quad18 \quad}$

Step-by-step explanation:

by tangent property we acquire:

$\displaystyle 3x - 6 = x + 10$

add 6 to both sides:

$\displaystyle 3x= x + 16$

cancel x from both sides:

$\displaystyle 2x= 16$

divide both sides by 2:

$\displaystyle x= 8$

so,

$\displaystyle PW = 3x - 6$

plug in the got value of x:

$\displaystyle PW = 3.8 - 6$

simplify multiplication:

$\displaystyle PW = 24- 6$

simplify Substraction:

$\displaystyle PW =18$

hence, The measure of PW is 18 unit
