Respuesta :

you would just break each one into 2 separate equations and solve for x/r. Then write the answer in between the two inequality signs- so the answers for 9 and 11 would look like this, just fill in the blanks with the answer you got: 3≤____<5, 2>___>-2.

0≤x-2<3
1
≤x-2    and  x-2<3

-1>2r-5>-9
-1>2r-5     and 2r-5>-9

this one just solve each one for z.
2z-1
≤5 or 3z-5>10
z≤3  or  x>5
