Mil dólares y un centavo:

Paolo is solving the inequality \( 15+2 x>31 \). To solve the inequality, he begins by solving the equation as shown. Which number line represents the solution to the inequality?

\begin{tabular}{l|l}-1) \( y=-2 x-1 \) \\ \( x \) & \( y \) \\ \hline-2 & \\ 0 & \\ 2 & \end{tabular}

Use the quotient rule to find the derivative of the following. \( y=\frac{x^{2}-3 x+7}{x^{2}+8} \)

Solve for \( y: 3(2 y+4)=4\left(2 y-\frac{1}{2}\right) \) The solution is \( y= \) The solution is
