Graph Real-World Scenarios

The video tutorial explains how to represent and graph inequalities on a number line using open and closed circles. It covers the symbols for less than, greater than, less than or equal to, and greater than or equal to. The tutorial provides examples of graphing inequalities and applies these concepts to real-world scenarios, such as the cost of a baseball bat and saving money. Key points include using open circles for strict inequalities and closed circles for inclusive inequalities.

What symbol is used to represent that a number is not included in the solution of an inequality?

• An open circle

• A closed circle

• A shaded line

• A dashed line

When graphing the inequality 'N is less than or equal to 12', what should you do on the number line?

• Place an open circle at 12 and shade to the left

• Place an open circle at 12 and shade to the right

• Place a closed circle at 12 and shade to the left

• Place a closed circle at 12 and shade to the right

If Sam's baseball bat costs more than $20, how would you represent this on a number line?

• Place a closed circle at 20 and shade to the right

• Place an open circle at 20 and shade to the left

• Place an open circle at 20 and shade to the right

• Place a closed circle at 20 and shade to the left

What does the phrase 'at least' imply in terms of inequalities?

• Greater than

• Greater than or equal to

• Less than or equal to

• Less than

How would you graph the inequality 'M is greater than or equal to 25' on a number line?

• Place an open circle at 25 and shade to the right

• Place a closed circle at 25 and shade to the left

• Place a closed circle at 25 and shade to the right

• Place an open circle at 25 and shade to the left
