In the xy-plane, what is the x-intercept of a certain line? (1) The line passes through the point (0,2). (2) The y-intercept of the line is 2. A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient. E. Statements (1) and (2) TOGETHER are NOT sufficient.
其实1,2说的是一个意思，所以你理解2就应该理解1
$10,000 is deposited in a certain account that pays r percent annual interest compounded annually, the amount D(t), in dollars, that the deposit will grow to in t years is given by D(t) = 10,000 {1+(r/100)}t. What amount will the deposit grow to in 3 years? (1) D(t) = 11,000 (2) r =10 A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient. E. Statements (1) and (2) TOGETHER are NOT sufficient. 答案是D，为什么(1)可以推出呢 ？
1是一个衡量，就是说无论取什么值都一样。其实是这个题可能记得有误，因为现实中基本不会发生这种情况，不必太concern这个题
