Question

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

Answer 1

-3x - 7 < 20
-3x < 20 + 7
-3x < 27
x > -27/3
x > - 9
open circle on -9, shaded to the right

Answer 2

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$-3x-7 <20$

solve for x

$-3x <20+7$

$-3x <27$ -----> Multiply by $-1$

$3x>-27$

$x>-9$

The solution is the interval--------> (-9, ∞)

All real numbers greater than $-9$ ( the number$-9$ is not included)
