Review Lesson 6-6: Let f(x) = 3x and g(x) = x2 - 1. Perform each function operation on the right and identify its equivalent expression in simplest form from the left.

the answer is c

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

$25 becasue a 10 increase would make it from 80 to 50
