If y=80 when x=32, find x when y=100.

Y        X

80     32

100    x'

Step-by-step explanation:

80x' = 100*32

80x' = 3200

x' = 3200/80

x' = 320/8

x' = 40

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
