2x-4(x+1)=-13
1) we solve this equation:
2x-4(x+1)=-12
2x-4x-4=-12
-2x=-12+4
-2x=-8
x=-8/-2
x=4
2) we evalute x²-1
x²-1=4²-1=16-1=15
Answer: 15
Answer:
12
Step-by-step explanation:
when + go to the other side it has to be -
w=16-4
=12
G(-4)
=1/2((-4)-1)
=1/2(-5)
=-2.5
------------------------------
f(g(-4))
=f(-2.5)
=2(-2.5)+1
=-5+1
=-4
Answer:
B
Step-by-step explanation:
It has a slope of -1/4
and it's y intercept is 2
y = -1/4x + 2
The answer would be A. -16
