Look at the cars mpg (miles per gallon) then multiple it by 15
Answer:
the answer is ( x-9) (x+1) = 0
Step-by-step explanation:
more to the solution is x= -1, 9
The equation y = -0.04x + 12 gives the number of gallons of gas in your car where x is the number of miles drivene
easy
y=gas left
x=miles
sub 200 for x
y=-0.04(200)+12
y=-8+12
y=4
4 gallons left
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
