8 0

Step-by-step explanation:

Distribute -3/4 with x and 8 which means multiply -3/4 with X and -3/4 with 8. Then leave the subtraction sign between the two.

It should look like -3/4x - (-3/4*8) = 1/2x-9

Now take your sum you got from -3/4*8 and add it to -9

Now that you have -3/4x left on one side and you have one sum on the right take 1/2x and subrtact it to -3/4 x so X is on one side. Last step is to divide your 2 total sums, hope this helps

What is the equation of the axis of symmetry of a parabola if its x-intercepts are –3 and 5?

melisa1 [442]

Answer:

x = 1

Step-by-step explanation:

The axis of symmetry is a vertical line and is located at the midpoint of the x- intercepts, thus

x = $\frac{-3+5}{2}$ = $\frac{2}{2}$ = 1

That is equation of symmetry is x = 1

Sholpan [36]

Answer:

x=2.17

Step-by-step explanation:

$x^2$ +18x+81=-4

-81 -81

$x^2$ +18x= -85

/18 /18

$x^2$ = -4.7

$\sqrt{x^2}$ = $\sqrt{-4.7}$

x= 2.17

I hope this helps :) (if it does, brainliest, please??)
