Answer:
I think its eight
Step-by-step explanation:
8 x 2 = 16 + 8 = 32

Answer:
f(x) = (x+10)^2 - 86
Step-by-step explanation:
- f(x) = x^2 + 20x - 86
- f(x) = x^2 + 20x + 100 - 86 (because (20/2)^2 = 100)
- f(x) = (x+10)^2 - 86
Completing the square means you do (b/2)^2 where b is: a^2x + bx + c.
Slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
we are given the points (-2,7) and (x,2)
slope is -1/3
so
(x,y)
(-2,7) and (x,2)
x1=-2
y1=7
x2=x
y2=2
slope=(2-7)/(x-(-2))=-1/3
slope=(-5)/(x+2)=-1/3
multiply both sides by (-3)(x+2) (basically cross multiply)
15=x+2
minus 2 both sides
13=x
x=13
the value of x is 13
