4. Graph the system of inequalities. Remember to shade for each inequality. Identify one solution for each graph. y > 2x-5
y > x-2

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

The answers are 20,30,80,180,960,890,1230,4560. on the first row

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
