Chapter 1, Problem 99

Simplify each inequality if needed. Then determine whether the statement is true or false. -8 > -|-6|

Verified step by step guidance
1
Identify the absolute value expression in the inequality: \(-|-6|\). Recall that the absolute value of a number is its distance from zero on the number line, always non-negative.
Calculate the absolute value: \(|-6| = 6\) because the absolute value of -6 is 6.
Substitute the absolute value back into the inequality: \(-8 > -6\).
Compare the two numbers on the number line: \(-8\) and \(-6\). Remember that on the number line, numbers to the right are greater.
Determine if the inequality \(-8 > -6\) is true or false based on their positions on the number line.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Absolute Value

The absolute value of a number is its distance from zero on the number line, always expressed as a non-negative value. For example, |-6| equals 6 because 6 is six units away from zero, regardless of the sign.

Inequality Symbols and Their Meaning

Inequality symbols like '>' indicate the relative size of two values. The symbol '>' means 'greater than,' so a statement like a > b is true if a is larger than b, and false otherwise.

Comparing Negative Numbers

When comparing negative numbers, remember that a number with a smaller absolute value is actually greater. For example, -8 is less than -6 because -8 lies further left on the number line.
