8(c-12)=40 that gonna be equal to 8c-96=-40 or 8c=-40+96 ,8c =56 divide both sides by 8 that equal to 7.....
The answer is A !!!!!!!!
the two segments AD and AB are equal therefore if you make the two equal to each other you will get the answer:
<span>x^2+2=11 then you subtract two to put x squared on the side by itself
</span>then you have <span>x^2=9
then all you have to do is take the square root of 9 and </span><span>x^2 and you get x=3
thefore the answer is A</span>

Answer:
vertex = (0, -4)
equation of the parabola: 
Step-by-step explanation:
Given:
- y-intercept of parabola: -4
- parabola passes through points: (-2, 8) and (1, -1)
Vertex form of a parabola: 
(where (h, k) is the vertex and 
is some constant)
Substitute point (0, -4) into the equation:
Substitute point (-2, 8) and 
into the equation:
Substitute point (1, -1) and into the equation:
Equate to find h:
Substitute found value of h into one of the equations to find a:
Substitute found values of h and a to find k:
Therefore, the equation of the parabola in vertex form is:
So the vertex of the parabola is (0, -4)
