Answer:
x ≥ 4
Step-by-step explanation:
Since there is a closed circle at x = 4, this indicates that x can be equal to 4
The line to the right is shaded indicating values of x greater than 4
Thus x ≥ 4 ← is the inequality represented in the number line
 
        
                    
             
        
        
        
Use the equation 
For A. The problem would be set up like so 
5 _ -1
--------
4 _ -2 
Start by subtracting 5 minus -1 which is 6 because minus a negative becomes a positive then subtract 4 minus -2 which is 6, remember minus a negative becomes a positive, then divide 6/6 to get 1 
For B. 
-5 _ -0
----------
3 _ -1 
Again subtract -5 by -0 which no matter what will be -5. Then make -1 positive because it's a subtracted negative so it becomes 3+1 which gives you 4. Your answer is -5/4
