Can someone please tell me what exactly I need to do??
I forgot how to do this..

1)

Rent-A-Car: R = $0.25m + $100

World Explorer: W = $0.15m + $125

2)

World Explorer is the cheapest option.

3)

World Explorer is the cheapest option.

Step-by-step explanation:

You pay $0.25 per mile driven = $0.25m

You owe a flat fee of $100

Rent-A-Car: R = $0.25m + $100

Similarly, you pay $0.15 per mile in the World Explorer

And a flat fee of $125

World Explorer: W = $0.15m + $125

Rent-A-Car:

World Explorer:

World Explorer is the cheapest option.

Rent-A-Car:

World Explorer:

World Explorer is the cheapest option.

-Chetan K

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:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
