Step-by-step explanation:

If we want to find the axis of symmetry of the parabola of $y=-4x^{2} -8x-7,$ we would use the formula of $-\frac{b}{2(a)}$ to find it.

b=-8

a=-4

so the formula would look like this $-\frac{-8}{2(-4)}$ , simplify it >>> $-\frac{-8}{-8}$ which is -1

So -1 would be the axis of symmetry

*It would mean a lot to me if you guys gave this post a "THANKS"

(3,0)

Step-by-step explanation:

Given inequalities,

y > –2x + 3

y < x – 2,

For (0,0),

0 > -2(0) + 3 ( False )

For (0,-1),

-1 > -2(0) + 3 ( False )

For (1, 1),

1 > -2(1) + 3 ( False )

For (3,0),

0 > -2(3) + 3 ( True )

0 < 3 - 2 ( True )

Hence, the order pair that makes both inequality true is,

( 3, 0)
