Put Y=x^2+10x+18 in vertex form

(-5,-7)

Step-by-step explanation:

Rewrite in Vertex form and use this form to find the vertex (h,k)

y = (x + 5)² - 7

Step-by-step explanation:

Given

y = x² + 10x + 18

To obtain vertex form use the method of completing the square

add/ subtract ( half the coefficient of the x- term )² to x² + 10x

y = x² + 2(5)x + 25 - 25 + 18

  = (x + 5)² - 7 ← in vertex form

Adam

Step-by-step explanation:

You just have to divide feet/second

Adam: 15 feet per second

15/1=15

Noah runs 599 feet in 40 seconds

599/40=14.9

Jake runs 1 mile in 384 seconds

1 mile=5280 feet

5280/384=13.8

liz runs 667 feet in 1 minute

1 minute=60 seconds

667/60=11.1
