Answer:
A
Step-by-step explanation:
f (x)=3x+5+6
g (x)=7
(f+g)(x)=|3x+5+6|+7
=|3x+11|+7
Answer:
y=-2x^2-8x-6
Step-by-step explanation:
We already have two x intercepts (-3,0) and (-1,0):
(-3,0) is the solution to x+3=0
(-1,0) is the solution to x+1=0
So what we have so far is (x+3)(x+1)=y
Now we do (x+3)(x+1)*?=y
Plug in (-5,-16):
(-5+3)(-5+1)*x=-16
(-2)(-4)*x=-16
8*x=-16
x=-2
So the equation is y=(x+3)(x+1)*-2 which is y=-2x^2-8x-6
Another possible graph is y=(x+1)(x+3)(x+3) or y=x^3+7x^2+15x+9
2x+3=4x+2
We solve this equation:
2x+3=4x+2
2x-4x=2-3
-2x=-1
x=-1/-2
x=1/2
Therefore: we have only one solution.
Answer: This equation have one solution; x=1/2.
