Which system of inequalities is represented by the graph?

Step-by-step explanation:

We observe in the graph that one line is horizontal, and its solution is the area above. Such line intercepts y-axis at , and the solutions are all numbers more than -1, that means its inequality is

The sign is the right one for this line, because the graph shows a solid line, which means that -1 is part of the solution.

If you observe all the options, you would see that the third choice is the only one that has included.

Therefore, the answer is

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
