Understanding Inequalities on the GED

This video tutorial covers solving inequalities on the GED, including word problems, algebraic expressions, and graphing solutions on a number line. It explains the meaning of inequality symbols, the process of solving inequalities, and the effect of dividing by negative numbers. The tutorial also provides practical examples and tips for understanding and solving different types of inequality problems.

What is the primary focus of this video tutorial?

• Solving quadratic equations

• Understanding inequalities on the GED

• Learning about geometry

• Studying calculus

In the context of inequalities, what does the symbol '>' represent?

• Less than

• Not equal to

• Equal to

• Greater than

If a meal costs $28 per person, how would you represent the total cost for x people?

• 28 / x

• 28 + x

• 28 * x

• 28 - x

When solving inequalities, what happens to the inequality sign when you divide by a negative number?

• It flips direction

• It becomes an equal sign

• It stays the same

• It disappears

What is the result of dividing 42 by -12 in the context of inequalities?

• -3.5

• 3.5

• 12

• 0

How do you solve an inequality involving fractions like 4/3?

• Subtract 4/3 from both sides

• Divide both sides by 4/3

• Add 4/3 to both sides

• Multiply both sides by 3/4

What does a filled-in circle on a number line indicate in inequalities?

• The number is included

• The inequality is reversed

• The inequality is invalid

• The number is not included

Which direction does the inequality x > -1.5 point on a number line?

• Up

• Right

• Down

• Left

Why does dividing by a negative number flip the inequality sign?

• Because it changes the value to zero

• Because it adds a constant to both sides

• Because it reverses the order of numbers

• Because it makes the inequality invalid

What is the main takeaway about inequalities from this video?

• They are only used in geometry

• They are irrelevant to the GED

• They require careful attention to signs

• They are simpler than equations
