From plans to ride a 15-mi bicycle trail. if his average speed is 20 mi/h, which equation can he use to find the time t, in hours, for the ride? a) t=20*15 b) t=20/15 c) t=20-15 d) t=15/20me u really need

lo.lll

step-by-step explanation:

the answer is 99.

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
