Answer:
B
Since the vertex is (-3,-2) The x value should be +3
Answer:
y = 5x^2+10x +14
Step-by-step explanation:
y = 5(x+1)^2+9
= 5(x^2+2x+1)+9
= 5x^2+10x +14
Answer:
I Know it is B trust me
Step-by-step explanation:
B-(-7)= -1
First negative multiply by negative is POSITIVE.
So: B+7= -1
Subtract 7 from both sides
B= -7-1
B= -8.
Answer: -8.
To Check Answer: Plug in the variable of B in the original equation.
So: -8-(-7)= -1
-8+7= -1
-1= -1
If the Solution works out the answer is right.
