Answer
Rebecca has 76 comic books
Maurice has 54 comic books
Step-by-step
Since there are 54 fewer comics and together they have 130 comics, you should subtract 54 from 130. Once you do that your answer will be 76; and that is how many comics Rebecca has. And 76+54=130 so Maurice has 54 comics

Answer:
Option A. (6,2)
Step-by-step explanation:
We have the following inequality:

Solving for y we have:

The line that limits the region of inequality is

Then the region of inequality are all values of y that are less than 
In other words, the points belonging to the inequality are all those that lie below the line.
To find out which point belongs to this region substitute inequality and observe if it is satisfied
A. (6,2)

<em> is satisfied</em>
B. (2, 6)

<em>it is not satisfied</em>
C. (2, -1)

it is not satisfied
<em>The answer is the option A</em>
