For each equation, decide if it is always true or never true. x - 13 = x + 1

x - 3 = 2x - 3 - x

2(x + 3) = 5x + 6 - 3x

3(x - 5) = 2(x - 5) + x

good luck on your studies! : )

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
