求助 OG11 黄皮 数学20题
20. Of the five coordinates associated with points A, B, C, D, and E on the number line above, which has the greast absolate value? (A) A (B) B 。。。 (E) E
一条数轴, 箭头向左,其间一段平均分成5等份,从左到右分别 A B C D E, 对应数字 -2 -1 0 1 2 A B C D E <—————————————— -2 -1 0 1 2
我想不通为什么答案是A
点A和E的绝对值应该是一样。 是不是题目错了??
OG解释:The absolate value of a number x is the distance between x and 0 on the number line. The coordinate of piont A is farthest from 0 and thus has the greast absolate value.
想不通! 还是我那根筋歪了?
