nothing can be further simplify in this problem
77/8= 9.625 and 31/4= 7.75...so 9.625-7.75= 1.875
Imaginary numbers ? just equate the imaginary with imaginary and real with real
<span>2ci 1=-d 6-ci <<< what the * is that ?

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>
7.5 i believe. not very good at math tho lol
