34題 題目是問 X intercept 是不是等於 Yintercept , 我想了又想 算出來 當條件一條件二 再一起 X intercept一定不等於 Y intercept (因為x= -y) 那等於是說兩條件再一起可以證明出 是不等於的 那這樣是不是應該選 C: BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient
数学小白同疑惑...我也觉得是B
我google了一下,beatthegmat上instructor的回答:
S:On GMAT when calculating factors and multiple of an integer X, should X be considered a factor and a multiple of itself.
Thanks.
I:If X is a positive integer, then yes. As an example, if X = 12, the multiples of X are ...-24, -12, 0, 12, 24, ... and the positive divisors of X are 1, 2, 3, 4, 6, and 12.
