Two cars, each with a different volume of gas in their tanks, start moving at the same time. However, the volume of gas in their tanks is used up at different rates. Assume the volumes are changing linearly. Volume in Tank (gal) Time (hr)15Car A17.2514.25Car B1915 How many hours will it take before both tanks have the same volume of gas in it?

8 hours

Step-by-step explanation:

−0.75x + 18 = -x+20

0.25x = 2

x = 8

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5
