Answer:

y = -5/8x +6

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (7/2 -11)/(4--8)

    = (7/2 - 22/2)/(4+8)

    = (-15/2)/(12)

   = -15/24

Divide top and bottom by 3

   -5/8

Then we can use point slope form to write the equation

y-y1 = m (x-x1)

y- 11 =-5/8(x--8)

y- 11 =-5/8(x+8)

Distribute

y-11 =-5/8 x -5

Add 11 to each side

y-11 = -5/8x -5+11

y = -5/8x +6

Use completing the square to solve this quadratic equation.
borishaifa [10]

Step-by-step explanation:

x² + 6x + 9 = 2

(x + 3)² = 2

x + 3 = ±sqrt(2)

x = -3 ± sqrt(2)

so, B and D are correct.

control :

(-3 + sqrt(2))² + 6(-3 + sqrt(2)) + 9 = 2

9 + 2 - 6sqrt(2) - 18 + 6sqrt(2) + 9 = 2

2 = 2

correct

(-3 - sqrt(2))² + 6(-3 - sqrt(2)) + 9 = 2

9 + 2 + 6sqrt(2) - 18 - 6sqrt(2) + 9 = 2

2 = 2

correct

(3 + sqrt(2))² + 6(3 + sqrt(2)) + 9 = 2

9 + 2 + 6sqrt(2) + 18 + 6sqrt(2) + 9 = 2

38 + 12sqrt(2) = 2

wrong.

(3 - sqrt(2))² + 6(3 - sqrt(2)) + 9 = 2

9 + 2 - 6sqrt(2) + 18 - 6sqrt(2) + 9 = 2

38 - 12sqrt(2) = 2

wrong.

Factor completely 15a^2b-10ab^2
ozzi

Find the Greatest Common Factor (GCF)

GCF = 5ab

Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

5ab(15a^b/5ab + -10ab^2/5ab)

Simplify each term in parentheses

<u>5ab(3a - 2b)</u>
