<span> An </span>equation<span> is a mathematical statement that shows the equal value of two expressions while an </span>inequality is a mathematical statement that shows that an expression is lesser than or more than the other. "<span>An 18-wheel truck stops at a weigh station before passing over a bridge. The weight limit on the bridge is 65,000 pounds. The cab (front) of the truck weighs 20,000 pounds, and the trailer (back) of the truck weighs 12,000 pounds when empty. In pounds, how much cargo can the truck carry and still be allowed to cross the bridge?" does this help?</span>
8 times 8 is 64.
The square root of 64 is 8.
The expression is
50h+25
50 times the number of hours, "h"
25 representing the one time service fee
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>
