Answer:
x=-3
Step-by-step explanation:
-2x2=-4
-4-16x-44=0
combine like terms (-4,-16)
-48-16x=0
move the 16x to the other side of the equal sign (add 16 since its -)
-48=16x
you need x alone so you need to divide by 16
-3=x

Answer: D. y-5= -7(x-8)
Step-by-step explanation:
point slope form: y-y1=m(x-x1)
slope= -7
point: (8,5)
use the slope and point and plug it into point slope form equation.
y-5= -7(x-8),
The Answer would be D. y-5= -7(x-8)
