Answer 2

Answer: a) see the graph below

b) n > 24/5 or 4.8

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
