Solving and Graphing Compound Inequalities

The video tutorial explains how to solve and graph value inequalities, focusing on the use of 'or' in solutions. It covers the steps to solve inequalities, graphing them on a number line, and understanding the difference between open and closed points. The lesson emphasizes the importance of graphing solutions separately and highlights key takeaways for students to remember.

What is the first step in solving a value inequality?

• Adding a constant

• Subtracting a constant

• Dividing by a constant

• Multiplying by a constant

After adding 3 to both sides of the inequality 7x > 21, what is the next step?

• Subtract 7 from both sides

• Add 7 to both sides

• Multiply both sides by 7

• Divide both sides by 7

What does the conjunction 'or' indicate in the context of inequalities?

• Both conditions must be true

• At least one condition must be true

• Neither condition must be true

• Both conditions must be false

How is an inequality with 'greater than' represented on a number line?

• With a closed circle

• With a dotted circle

• With a shaded circle

• With an open circle

What does a closed circle on a number line represent?

• Less than

• Greater than

• Greater than or equal to

• Less than or equal to

If x is greater than 3, which direction do we shade on the number line?

• Neither direction

• To the left

• Both directions

• To the right

If x is less than or equal to 0, which direction do we shade on the number line?

• Neither direction

• Both directions

• To the right

• To the left

What is the main takeaway when dealing with 'or' in inequalities?

• Ignore one of the inequalities

• Combine the inequalities

• Solve and graph separately

• Solve only one inequality

When graphing two solution points, where should they be placed on the number line?

• At the ends

• At the center

• At the same point

• At different points

What is the key difference in this lesson compared to the last class?

• Graphing on a different axis

• Using 'and' instead of 'or'

• Using different numbers

• Adding the conjunction 'or'
