Question

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

Answer 1

`\begin{gathered} 3y^2+(15y)/(x) \\ \\ \end{gathered}`

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

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