Answer:
It is a solution.
Step-by-step explanation:
Plug in (-1,2) to both equations:
Plug in -1 to see if 2 comes out:
f(x)=x^2+3x+4
y=(-1)^2+3(-1)+4
y=1-3+4
y=-2+4
y=2
(yes it works)
g(x)=2x+4
y=2(-1)+4
y=-2+4
y=2
(yes it works)
Answer:
4 =x
Step-by-step explanation:
-3(x+4) = 4(x-10)
Distribute
-3x-12 = 4x - 40
Add 3x to each side
-3x -12 +3x = 4x +3x-40
-12 = 7x-40
Add 40 to each side
-12 +40 = 7x - 40+40
28 = 7x
Divide each side by 7
28/7 = 7x/7
4 =x
