49 which two inequalities can be used to solve the inequality |3x - 7| < = 15i. 3x – 7 ≤ -15 ii. 3x – 7 ≤ 15 iii. 3x – 7 ≥ -15 iv. 3x – 7 ≥ 15 answers: i only ii only i and iii ii and iii

The answer is II and III, which is the last choice from above.  This is because the symbol "less than (or equal to)" indicated a conjunction, which means we have to take into account that the absolute value can be less than or equal to 15, and greater than or equal to -15.  This solution set falls in between the two values, hence, the conjunction.

The answer would be $68.04
