Solving Absolute Value Inequalities

This video tutorial covers solving absolute value inequalities, starting with basic examples and progressing to more complex cases, including those with no solutions, infinite solutions, and fractions. The video provides step-by-step instructions, tips, and tricks to simplify the process. Viewers are encouraged to practice with a problem provided at the end and are directed to additional resources for further learning.

What is the main goal of this video tutorial?

• To understand linear equations

• To master solving absolute value inequalities

• To learn how to solve quadratic equations

• To explore complex numbers

What is the first step in solving an absolute value inequality where the absolute value is already isolated?

• Multiply both sides by a variable

• Add a constant to both sides

• Write two separate inequalities

• Subtract a constant from both sides

When the absolute value is not isolated, what should you do first?

• Add a constant to both sides

• Isolate the absolute value

• Subtract a constant from both sides

• Multiply both sides by a variable

What is a key trick to avoid finding common denominators when dealing with fractions in absolute value inequalities?

• Multiply both sides by the common denominator

• Add fractions directly

• Divide both sides by the common denominator

• Subtract fractions directly

How do you represent solutions on a number line when using interval notation?

• Use only open circles

• Use only closed circles

• Use parentheses and brackets

• Use arrows and lines

What is the first step in solving a complex absolute value inequality where the absolute value is not isolated?

• Subtract a constant from both sides

• Multiply both sides by a variable

• Isolate the absolute value

• Add a constant to both sides

What does it mean if an absolute value inequality has no solutions?

• The inequality has infinite solutions

• The inequality is always false

• The inequality is always true

• The inequality has a single solution

How do you represent infinite solutions on a number line?

• Use closed circles only

• Use open circles only

• Shade the entire line

• Shade only one point

What is the benefit of using a trick to simplify complex inequalities with fractions?

• It makes the solution more accurate

• It avoids the need for common denominators

• It increases the number of solutions

• It decreases the number of solutions
