Question

use your equation from part b to predict the highway MPG for a car that gets 68 MPG in the city.part b equation:$y = \frac{7x}{9} + \frac{125}{9}$

Answer 1

$\text{ y = }\frac{7x}{9}\text{ + }\frac{125}{9}$

ok

$\begin{gathered} \text{ y = }\frac{7(68)}{9}\text{ + }\frac{125}{9} \\ \\ \text{ y = }\frac{476}{9}\text{ + }\frac{125}{9} \\ \\ \text{ y = }\frac{601}{9} \\ \\ \text{ y = 66.8 } \end{gathered}$

MPG = 66.8
