Graphing Solutions: Inequality

The video tutorial explains inequalities, their symbols, and how to graph them on a number line. It covers the use of closed and open circles to represent inclusive and exclusive inequalities, respectively. The tutorial includes examples of word problems involving saving money, temperature, and carnival expenses, demonstrating how to graph these scenarios using inequalities.

What symbol is used in an equation to show equality?

• Not equal to

• Equal to

• Greater than

• Less than

How is an inequality that includes 'or equal to' represented on a number line?

• With a closed circle

• With an open circle

• With a shaded area

• With a dashed line

If X is less than 12, how would you graph this on a number line?

• Closed circle on 12, shade to the right

• Open circle on 12, shade to the right

• Open circle on 12, shade to the left

• Closed circle on 12, shade to the left

Jackie wants to save at least $30. How would you write this as an inequality?

• S ≤ $30

• S ≥ $30

• S > $30

• S < $30

Ben says the temperature will be below 40 degrees. How is this represented as an inequality?

• T < 40

• T > 40

• T ≥ 40

• T ≤ 40
