Jose is driving on the highway. He begins the trip with 12 gallons of gas in his car. The car uses up one gallon of hay every 30 miles. Let G represent the number of gallons of gas he has left in his tank, and let D represent the total distance (in miles) he has travels. Write an equation relating G to D, and then graph your equation using the axes above.

Respuesta :

The initial gallon of gas at the beginning of the trip is 12.

Then, for every 30 miles, the car uses one gallon, we have;

[tex]\begin{gathered} G=12-\frac{1}{30}D \\ G=12-\frac{D}{30} \end{gathered}[/tex]

Using the equation below to plot the graph of the relation, we have;
