Question

if x = 5 and y= -2 then 3y^2 + 15y/x=

Answer 1

$\begin{gathered} 3y^2+\frac{15y}{x} \\ \\ \end{gathered}$

Substitute in the equation the variables by the given values and evaluate:

$\begin{gathered} 3(-2)^2+\frac{15(-2)}{5} \\ \\ =3(4)+\frac{-30}{5} \\ \\ =12-6 \\ \\ =6 \end{gathered}$Then, the given expression is equal to 6
