Step-by-step explanation:
a) 
b) 
c) 
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.

Diagram:
M------------O-------------N
................. ^ midpoint
Obviously if O is the *mid*point, then it is exactly halfway between M and N. That also means it has bisected the segment into two equal parts.
On one side you have MO (or OM, if you like)
On the other side you have ON.
In order for O to be the midpoint:
ON = OM
