Answer:
The graph in the attached figure
Step-by-step explanation:
we have
[tex]-3x-7 <20[/tex]
solve for x
[tex]-3x <20+7[/tex]
[tex]-3x <27[/tex] -----> Multiply by [tex]-1[/tex]
[tex]3x>-27[/tex]
[tex]x>-9[/tex]
The solution is the interval--------> (-9, ∞)
All real numbers greater than [tex]-9[/tex] ( the number[tex]-9[/tex] is not included)
