What is the value of xy?Statement 1: x + y = 10Statement 2: x - y = 6a...
(1) Given x + y = 10, or y = 10 - x, it follows that xy = x(10 - x), which does not have a unique value. For example, if x = 0, then xy = (0)(10) = 0, but if x = 1, then xy = (1)(9) = 9; NOT sufficient.
(2) Given x - y = 6, or y = x - 6, it follows that xy = x(x - 6), which does not have a unique value. For example, if x = 0, then xy = (0) (-6) = 0, but if x = 1, then xy = (1)(-5) = -5; NOT sufficient.
Using (1) and (2) together, the two equations can be solved simultaneously for x and y. One way to do this is by adding the two equations, x + y = 10 and x - y = 6, to get 2x = 16, or x = 8.
Then substitute into either of the equations to obtain an equation that can be solved to get y = 2. Thus, xy can be determined to have the value (8)(2) = 16. Alternatively, the two equations
correspond to a pair of nonparallel lines in the (x,y) coordinate plane, which have a unique point incommon.
The correct answer is C

What is the value of xy?Statement 1: x + y = 10Statement 2: x - y = 6a...
Understanding the Problem
To find the value of xy, we need to analyze the two statements provided:
- Statement 1: x + y = 10
- Statement 2: x - y = 6
Let's evaluate each statement individually and then together.
Analyzing Statement 1
- From x + y = 10, we can express y in terms of x:
- y = 10 - x
- However, this does not give us a specific value for xy without knowing x or y individually.
Conclusion for Statement 1
- Statement 1 alone is insufficient.
Analyzing Statement 2
- From x - y = 6, we can express y in terms of x:
- y = x - 6
- Similar to Statement 1, this alone does not provide enough information to find a specific value for xy without knowing x or y.
Conclusion for Statement 2
- Statement 2 alone is also insufficient.
Combining Both Statements
- Now, let's combine the two statements:
1. From Statement 1: x + y = 10
2. From Statement 2: x - y = 6
We can solve these two equations simultaneously:
1. Adding both equations:
- (x + y) + (x - y) = 10 + 6
- 2x = 16
- x = 8
2. Substituting x back into one of the equations to find y:
- x + y = 10
- 8 + y = 10
- y = 2
Now we can find xy:
- xy = 8 * 2 = 16.
Conclusion for Combined Statements
- Both statements together are sufficient to find the value of xy.
Thus, the answer is option C: BOTH statements (1) and (2) TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
