8. Mylie's family car has a 14 gallon gas tank. The car uses about 0.5 gallons of gas each day. A warning light comes on when the fuel left in the tank is 1.5 gallons or less.
a. If Mylie's family starts with a full tank (14 gallons), can they drive the car for 15 days with out the warning light
coming on? Explain how you know

yes

Step-by-step explanation:

Mylie's car has 14 gallons of gas. But if we use 0.5 a day we should figure out how many days she can use it. 14*2=28. 28-15 is 13 which is above 1.5.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
