% = (Change/Original) * 100
= (6/24) * 100
= (0.25) * 100
= 25%
Each of the 4 friends spent 15 dollars so all you need to do is multiply 4 by 15. 4x15=60
X= 36 I think
Hope this helps
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>
