Which system of equations does not have the same solution as the system below?
4x + 3y = 10
-6x - 5y = -16
1) -12x - 9y = -30
12x + 10y = 32
2) 20x + 15y = 50
-18x -15y = -48
3) 24x + 18y = 60
-24x - 20y = -64
4) 40x + 30y = 100
36x + 30y = -96

okay so get photo math and it will solve every math problem you have and if yo uhave other questions about any ohter subject i can give you other apps

Step-by-step explanation:

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
