I'm going to go with C.
The inequality isn't greater than OR EQUAL TO which marks out B and D.
The inequality is showing that it is greater than -21 meaning that the shaded area should be towards the positive which in turn marks out A.

First, you solve or simplify the inequality.

Divide everything by 3.
6x - y < -7

Subtract 6x from both sides.
-y < -6x - 7

Divide everything by -1
y > 6x + 7

Since there isn't a line under the sign, it will be a dotted line on the graph. And since it is greater than, the right side of the line will be shaded. Therefore, the answer is C

ashleigh rode her bicycle 26.5 miles in 4 hours which gives the best estimate of how far ashleigh rode in 1 hour.
Advocard [28]
26.5 miles in 4 hours is stating 26.5 miles per 4 miles.
To find out how far it is in one mile, you can either make a proportion or divide 26.5 miles per mile by 4.
Division:
\frac{26.5}{4}/ \frac{4}{4}
\frac{26.5}{4}=6.625
\frac{4}{4}=1
26.5 miles per 4 hours = 6.625 mph
Proportions:
\frac{26.5}{4}= \frac{x}{1}
26.5=4x
6.625=x
In one hour, Ashleigh traveled 6.625 miles in 1 hour.
