Answer:
6
Step-by-step explanation:
-3x=-27+9
-3x=-18
x=-18/-3
x=6
Multiply the first equation by 3
21x+15y=-6
Add this to the second equation
21x+15y=-6
-21x-15y=6
0+0=0
True
Final answer: Infinitely Many Solutions (they are coinciding lines)
Nvm wait I read the question wrong. The real answer would be 28, 28, 36
Since these are parabolas with y being squared, the standard form of such a parabola with vertex at (h, k) is
<span>x = a(y - k)^2 + h </span>
<span>There are no steps. Just look at what is inside the parentheses and compare it to (y - k) with k = -3. </span>
<span>Then look at what is added and compare it to h = -1. </span>
<span>For instance, A has (y + 1) in parentheses. So k = -1. And it has -3 added, so h = -3. That would be a vertex at (-3, -1).</span>
