Step-by-step explanation:
the simple answer is -270000
I’m not too sure but I think it’s C
For this case we have the following inequality:
x> -9
The solution set of this inequality is given by:
(-9, inf)
Therefore, all the points within the given interval must belong to the graph of the inequality.
Note: see attached image.
