Answer:

-68/7

Step-by-step explanation:

slope1 of Car 1 that pass (-5,-8) (2,7)

= (y1-y2)/(x1-x2)=(2-(-5))/(7-(-8))=7/15

Slope2 of car 2 that pass (5,1) (10,y)

slope 1 and slope2 are perpendicular =>slope 2 =-15/7

make slope2 y=(-15/7)x+b

for it pass(5,1) => 1=(-15/7)5+b =>b=82/7 => y=(-15/7)x+82/7

put (10,y) in => y=(-15/7) 10+82/7=-68/7

Complete the square y=x^2+6x+8
andreyandreev [35.5K]

Answer:

y = (x+3)² - 1

Step-by-step explanation:

To complete the square take the middle term b and divide by 2. Then square the value.

Here b = 6.

So 6/2 = 3

3² = 9

Add 9 to both sides of the equation.

x² + 6x + 8 = 0

x² + 6x + 9 + 8 = 9

(x+3)² - 1 = y
