Answer: Choice C

Graph with filled in circles at d = 0 and d = 2, shading in between
==========================================
Explanation:
d = amount downloaded in gigabytes
The smallest amount is d = 0. We cannot download a negative amount of data, so this is why d = 0 is the smallest.
The largest amount allowed is d = 2. This is the cap that the ISP has set up.
So basically d can be anything between d = 0 and d = 2, including both endpoints. This means 
We use filled in circles for both endpoints to show to the reader "include these endpoints". Shading is done in between to show the entire solution set of possible d values. For instance d = 1 is in that region so it is possible to have this solution. Something like d = 4 is outside the region and not possible.
<span>h = Williams hours
h + 2.5 = Jose's hours because he worked 2.5 hours more than William, so you add 2.5 to William's hours (which is represented by h) to get Jose's hours
then you add them together..</span><span>
</span>
6,12,8,10,16
6+6=12-4=8+6=14-4=10+6=6
The pattern I noticed is it adds 6 and then it minus 4.
Zero
There is no solution for these equations as there is no even one point of intersection between them
Answer:
105 min
Step-by-step explanation:
60 minutes ÷ 4 miles= 15 minutes per mile
