3x+5=2x-10
-2x -2x
X+5=-10
-5 -5
X=-15
3(-15)+y=5
-45+y=5
+45 +45
y=50
2(-15)-y=10
-30-y=10
+30 +30
-y=40
Divide by -1 on both sides
y=-40
Answer:
B, f(x)..g(x).dx + ?.............. I think these is ansewer
Answer:
-2x^2-8x+12 if you meant the second function to be g(x)=5x^2+6x-8
If you didn't mean that please let me know in the comments so I can change my answer
Step-by-step explanation:
f-g=
3x^2-2x+4
-(5x^2+6x-8)
--------------------
-2x^2-8x+12
