Understanding Absolute Values and Inequalities

What is the result of evaluating the expression |4 - 7| + |-10 + 2|?

• 5

• 11

• 1

• 9

How do you represent the inequality X < -3 or X > 3 on a number line?

• A single line from -3 to 3

• Open circles at -3 and 3

• Closed circles at -3 and 3

• Shaded region between -3 and 3

What does the absolute value notation |x| > 3 mean in terms of inequalities?

• X is equal to 3

• X is greater than -3 and less than 3

• X is less than -3 or greater than 3

• X is between -3 and 3

How would you express the inequality -8 ≤ X ≤ 8 using absolute value notation?

• |x| ≥ 8

• |x| ≤ 8

• |x| < 8

• |x| > 8

What does the absolute value notation |x| ≤ 8 indicate about the values of X?

• X is greater than 8

• X is exactly 8

• X is less than -8

• X is between -8 and 8, inclusive
