Solving and Graphing Compound Inequalities

This video tutorial introduces compound inequalities, focusing on conjunctions and disjunctions. It explains how conjunctions use 'and' to combine inequalities, requiring both to be true, and how disjunctions use 'or', allowing either inequality to be true. The tutorial includes examples and graphing techniques for both types, emphasizing the differences in their graphical representations on a number line.

What are the two types of compound inequalities?

• Conjunctions and Disjunctions

• Additions and Subtractions

• Multiplications and Divisions

• Equations and Inequalities

In a conjunction (AND) inequality, what must be true?

• At least one inequality must be false

• Both inequalities must be true

• Only one inequality must be true

• Neither inequality must be true

How do you graph a conjunction (AND) inequality on a number line?

• Shade the entire number line

• Shade the region where both inequalities overlap

• Shade the region where either inequality is true

• Shade the region outside the inequalities

What does a disjunction (OR) inequality represent?

• Only one inequality must be true

• Both inequalities must be false

• Both inequalities must be true

• Neither inequality must be true

How do you graph a disjunction (OR) inequality on a number line?

• Shade the entire number line

• Shade the regions where either inequality is true

• Shade the region where both inequalities overlap

• Shade the region outside the inequalities

When solving a compound inequality with AND, what form does the solution take on a number line?

• A line segment

• A single point

• The entire number line

• Two separate regions

When solving a compound inequality with OR, what form does the solution take on a number line?

• A line segment

• A single point

• Two separate regions

• The entire number line

How do you read a double inequality?

• From left to right

• From right to left

• From the inside out

• From the outside in

What is the solution set for the inequality: T > 0 or T < 2?

• All real numbers

• No solution

• Only positive numbers

• Only negative numbers

What does the graph of the inequality X > 3 and X < 5 look like?

• A single point at 4

• A line segment between 3 and 5

• Two separate regions

• The entire number line
