Answer: a) see the graph below
b) n > 24/5 or 4.8
Step-by-step explanation:
a) see the graph below.
-2 is smaller and equal to x, so the point is close circle; and 3 is only greater than x, so it only has open circle, and the line was between the range from -2 to 3.
b) 5n + 3 >27
5n > 24 [Subtradt 3 from both side]
n > 24/5 or 4.8
