Example: Solving and Graphing 12d≤6012d \leq 60

The linear inequality 12d≤6012d \leq 60 is solved using the Division Property of Inequality. By dividing both sides by the positive number 1212, the inequality symbol remains unchanged, simplifying the statement to d≤5d \leq 5. To graph the solution on a number line, a right bracket is placed at 55 and shading is applied to the left. In interval notation, this solution set is denoted as (−∞,5](-\infty, 5].
