Question

1. students have no more than 90 minutes to complete a test. write and graph an inequality that represents the time in minutes m students have to complete the test. (example 3)

Explanation:

Step1: Analyze the word "no more than"

"No more than" means less than or equal to. So the inequality is \(m\leq90\).

Step2: Graph the inequality

On a number line, draw a closed circle at \(90\) (because \(m = 90\) is included in the solution set, due to the "or equal to" part of "less than or equal to") and draw an arrow to the left (since \(m\) can be any value less than \(90\)).

Answer:

The inequality is \(m\leq90\). To graph it, place a closed - circle at \(90\) on the number line and draw an arrow to the left.
