The formula for a vertex form equation is

in which (h,k) represents the vertex
Your equation is in vertex form, if you mpve the -7 to the other side you will get

because you have to add 7 to both sides
based on the equation,
h=10
k=7
(h,k)=(10,7)
your vertex is (10,7)
Answer:

Step-by-step explanation:
Answer:
x = 2.5
Step-by-step explanation:
x = 5 - x

2x = 5
2x/2 = 5/2
x = 2.5
I think your answer is c but I'm not sure
Just distribute and add
2(x)+3(x)
2x+3x
5x====> Answer
