3 Coached Example
1 answer:
Since 8 is subtracted from z, add 5 to both sides.
z - 8 + 5 <span>≤ 5 + 8
z </span><span>≤ 13
</span>
Graph the solution set on the number line below.
(The Graph will be at the bottom of the page).
Since the symbol is <span>≤, draw a(n) less than circle or equal to circle at 13.
</span>
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 <span>≤ 13, its graph is shown above.</span>
