To solve the inequality 5x - 2 ≤ 8, you can start by isolating the variable, x.
Add 2 to both sides of the inequality:
5x - 2 + 2 ≤ 8 + 2
5x ≤ 10
Divide both sides of the inequality by 5 to solve for x:
(5x)/5 ≤ 10/5
x ≤ 2
The solution to the inequality is x ≤ 2.
Since the inequality includes the equal sign (≤), the solution is closed.
To determine where the shading should be, you would shade to the left side of the number line.
Therefore, the answer is a) x > 2
