Answer:
C
Step-by-step explanation:
When an equality has a ≤, or ≥ sign (greater than/less than or equal to), the line will be solid. When an equality has a <, or > sign(greater than/less than), the lines will be dotted. As we can see, both of the inequalities given have <, or >, meaning they must both have dotted lines. Since one of the lines in D is solid, the correct answer is C.
If you would like to know which unit rate is equivalent to 17 miles per gallon, you can calculate this using the following steps:
17 miles ... x gallon = ?
51 miles ... 3 gallons
x = 17 * 3 / 51 = 1 gallon
17 miles ... x gallon = ?
34 miles ... 4 gallons
<span>x = 17 * 4 / 34 = 2 gallons</span>
The correct result would be: fifty-one miles over three gallons.
