I see your last line is : c(x) = 0.9(x^2-10)^2 + 101.1
Let y = x^2, then c(y) = 0.9(y-10)^2 + 101.1
Apparently, c(y) is a parabola, min is 101.1 when y = 10, max is infinity
So let x^2 = 10 -> x = sqrt(10) or -sqrt(10), min is 101.1, max is infinity

<span>6x-7y=-84
7y = 6x + 84
y = 6/7(x) + 12</span>
<span>D. Line AE equals about line ED because if you measure line AE it is the same length as line ED</span>
Answer:
