Answer 1

Since 8 is subtracted from z, add 5 to both sides.

z - 8 + 5 ≤ 5 + 8

z ≤ 13

Graph the solution set on the number line below.
(The Graph will be at the bottom of the page).

Since the symbol is ≤, draw a(n) less than circle or equal to circle at 13.

This shows that 13 is a solution.

Since all values less than 13 are also solutions, draw an arrow to the left. 

The solution set for the inequality is z ≤ 13, its graph is shown above.
