Question

Which graph represents the solution set for the inequality 8z≤ 16?

Answer 1

The graph in the attached figure

Explanation:

we have

`8z\leq 16`

Solve for z

Divide by 8 both sides

`z\leq 16/8`

`z\leq 2`

The solution for z is the interval ----> (-∞,2]

All real numbers less than or equal to 2

In a number line the solution is the shaded area at left of z=2 (closed circle)
