Answer:
from 0 to 12 hours, that is 
Step-by-step explanation:
Notice that the x represents the number of phone hours used, therefore it has to be a number larger or equal zero, but NOT a negative number.
So on one end we have that the number of phone hours used (x) must be larger or equal zero: 
On the other hand, when the battery goes to zero, there are no more phone hours to use. We can find what is that other limit by making the battery percent (y variable) equal to zero, and solve the equation for x, thus giving us the upper limit of usable phone hours:
Therefore, the upper limit for the number of usable phone hours is 12 hours.
Then we write:
hours

Inequalities help us to compare two unequal expressions. The correct option is B.
<h3>What are inequalities?</h3>
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given inequality -6 ≤y + 2x < 15 can be broken into two small inequality, as shown below.
Now, if we plot the inequality as shown below, then the area in which both the shaded region overlap is the area of the this inequality.
Hence, the correct option is B.
