Question

Which graph shows the solution to the inequality -3x-7 <20?
-
105
10
-10

Answer 1

Last answer (bottom most graph)

Explanation:

-3x - 7 < 20

-3x < 20 + 7

-3x < 27

- x < 27/3

- x < 9

x > 9 (flip inequality sign when multiplying both sides by -1)

The only graph that shows that the value of x is greater than 9 is the bottom answer
