 Question 295391: I understand the absolute-value notation are in bars, not parentheses or brackets. I also understand if there is a negative number in the bars, the absolute value becomes a positive number...... the question is: The absolute value of negative seven is less than or equal to seven. choices: a. | –7 | = 7 b. | –7 | < 7 c. | –7 | ≤ 7 d. | –7 | ≥ 7 I choose a and so did the teacher. Other students questioned her about it and now she is saying a is the wrong answer. I choose a because the question asked the absolute value of -7, | –7 | is less than or = to 7. Since the absolute value of -7 is 7 it cannot be less than...because they are equal. this is how I understand...please correct me if i'm wrong. if a isn't the correct answer, then none of the choices she gave would be right. b. | –7 | < 7 ~ the absolute value of -7 is 7 . 7 cant be less than 7 because 7=7 c. | –7 | ≤ 7 ~ the absolute value of -7 is 7. 7 does = 7 but is it not less than 7 d. | –7 | ≥ 7 ~ the absolute value of -7 is 7. 7 does = 7 but is it not greater than 7 THANKS!!
