Respuesta :

Solve inequalities the way you would solve an equation except for this rule-
If you multiply or divide a negative, the sign must be switched.

Do the inverse of everything like in an equation-
4x-1> -9
+1      +1 (Add 1)
4x>-8
/4    /4     (Divide 4)
You are not dividing a negative number from another number.  So keep the sign.
x>-2
Your answer is C.
