Hello,
Please, see the attached file.
Thanks.
Solve each
5x+7>-8
minus 7 both sides
5x>-15
divide by 5
x>-3
3x+7≤19
minus 7 both sides
3x≤12
divide by 3
x≤4
so we got
x>-3 AND x≤4
and means that the solution set must satisfy both at once
so x is bigger than -3 and less than or equal to 4
so between -3 and 4 including 4
-3<x≤4
last one
For a compression, a has to be less than one, and for a shift to the right, h has to be negative
the only one to meet both criteria is D
The correct answer is choice C. both symbols stand for division
