Answer:

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

A bike rental company charges $10 plus a charge per for the distance ridden. the total cost, t, can be represented by the equati

goblinko [34]

Answer:

$c=\frac{t-10}{m}$

Step-by-step explanation:

$t=10+cm$

Subtract 10 from both sides:

$t-10=cm$

Divide both sides by $m$ :

$\frac{t-10}{m}=c$

Placing $c$ on the left:

$c=\frac{t-10}{m}$

For example, if the total charge is $27.50 and the distance ridden is 250 mi, we can calculate the additional cost per mile, as such:

$c=\frac{27.50-10}{250}$

$c=0.07$
