Example: Solving and Graphing 12d6012d \leq 60

The linear inequality 12d6012d \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 d5d \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].
