Step-by-step Solution

To convert each of the given sentences into absolute value inequalities, we can use the definition of absolute value, which states that the absolute value of a number represents its distance from zero on the number line. Here are the conversions for each sentence: (a) All real numbers \( x \) less than 4 units from 8: \[ |x - 8| < 4 \] (b) All real numbers \( x \) more than 7 units from 0: \[ |x| > 7 \] (c) All real numbers \( x \) at least 9 units from 7: \[ |x - 7| \geq 9 \] (d) All real numbers \( x \) at most 4 units from 3: \[ |x - 3| \leq 4 \] These inequalities represent the conditions described in each sentence.

Quick Answer

(a) \( |x - 8| < 4 \) (b) \( |x| > 7 \) (c) \( |x - 7| \geq 9 \) (d) \( |x - 3| \leq 4 \)
