The independent variable is time, which varies from 0 to 0.5, so domain = [0,0.5].
The distance travelled is the dependent variable, varying from 0 to (1/2)80=40 km. The range is therefore [0,40].
Note: in interval notation, a square bracket means that the value is included in the interval.
The answer would be C) y</=x-14
The steps to get this are:
1) Add 5y to both sides to remove the negative 5y
2) Subtract 70 from both sides to isolate 5y
3) Divide everything by 5 to simplify
That's how to get the answer. Hope this helps
