Skylar is driving on a long road trip. She currently has 9 gallons of gas in her car. Each hour that she drives, her car uses up 1 gallon of gas. How much gas would be in the tank after driving for 5 hours? How much gas would be left after tt hours?

4 gal after 5 hours

Step-by-step explanation:

y = 9 - x

y = 9 - 5

Y = 4

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
