Difference quotient
Nina [5.8K]
f(x)=5x^2-5x-6
\\ \quad \\

\begin{cases}
f(\boxed{x+h})=5(\boxed{x+h})^2-5(\boxed{x+h})-6
\end{cases}\qquad thus
\\ \quad \\
\cfrac{f(x+h)-f(x)}{h}\qquad \textit{will be then}
\\ \quad \\
\cfrac{[5({x+h})^2-5({x+h})-6]\quad -\quad [5x^2-5x-6]}{h}
\\ \quad \\
\cfrac{[5(x^2+2xh+h^2)-5(x+h)-6]-[5x^2-5x-6]}{h}


\cfrac{\underline{5x^2}+10xh+5h^2\underline{-5x}-5h\underline{-6}\underline{-5x^2}\underline{+5x}\underline{+6}}{h}\impliedby \textit{canceling those ones}
\\ \quad \\
\cfrac{10xh+5h^2-5h}{h}\impliedby \textit{common factor}
\\ \quad \\
\cfrac{5\underline{h}(2x+h-1)}{\underline{h}}

and surely, you'd know what that is

A. \angle7 and \angle8 are congruent because they are opposite to one another across the intersection of lines C and D. (We call \angle7 and \angle8 a "vertical angle pair".)

B. For the same reason \angle7 and \angle8 are congruent, we know that the angles with measures 5y-29 and 3y+19 are also congruent. This means 5y-29=3y+19, which we can solve for y.

C. 5y-29=3y+19\implies2y=48\implies y=24

While vertical angle pairs are congruent, adjacent angle pairs are supplementary. This means that 5y-29 and the measure of \angle7 (or \angle8) add to 180 degrees. Similarly, 3y+19 and the measure of \angle7 (or \angle8) also add to 180 degrees.

With y=24, we find

m\angle7+(5y-29)^\circ=180^\circ\implies m\angle7=180^\circ-(5(24)-29)^\circ

\implies m\angle7=m\angle8=89^\circ
