Match the inequality to the graph of its solution.
a. n/4 ≤ -1
b. -10 ≥ -100
c. 5x ≥ 20

Part (a):
The given inequality is: 
n/4 ≤ -1
we need to isolate the n on one side of the inequality. To do this, we will multiply both sides by 4 as follows:
n/4 x 4 ≤ -1 x 4
The inequality now is:
n ≤ -4
The correct graph representing this is graph (b)

Part (b):
The given inequality is: 
-10 ≥ -100
So, we will just search for the graph the shows that -10 is greater than the -100
The correct graph representing this is graph (a)

Part (c):
The given inequality is:
5x ≥ 20
we need to isolate the x on one side of the inequality. To do this, we will divide both sides by 5 as follows:
5x/5 ≥ 20/5
The inequality now is:
x ≥ 4
The correct graph representing this is graph (c)
