Answer:
First we need to solve:
3x + 9 < 30
-9 -9
3x < 31
Divide by 3 on both sides:
x < 10.3 around 10
this doesn't really seem right are you sure you typed it in correctly?
Explanation:
x < 10 im assuming its 13 i guess since there are no options of 10..
so:
x < 13
B is your answer
The circle is filled in, and it starts at the point of 13 and goes down.
