Sum= 348. you didn't have to regroup because no number went over 10

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:
$150012.84 or $150013 rounded
The growth factor is 1.07
Step-by-step explanation:
First create the equation:
y=1.07x+150,000
Then substitute:
y=1.07(12)+150,000
Calculate:
y=150012.84
4(x+2y) (x-2y)
hope this helps
