Answer:
Step-by-step explanation:
so why this kind of problem is so confusing is b/c it's 2 problems in one
if you were to expand this it look like this
10 ≤2x
and
2x ≤x+9
This is really saying.. that x has a range.. and that the 1st equations is the lower stop point, and that the 2nd equations is the upper stop point
once it's taken apart.. I bet you can solve it pretty quickly.
5≤x
and
x ≤9
then just put it back together in that confusing .. yet handy way to write it,
5≤x≤9
