3x + 6y = 42 and -7x + 8y = -109 solve by elimination

Point Form

(15,-1/2

Equation Form

x=15 and y= -1/2

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

do you have an easier question cause this shh is hard like theheck
