Let x, y be real numbers satisfying:
56x + 33y = –y/(x2 + y2) 33x – 56y = x/(x2 + y2)
Find the value of
|x| + |y|
If x + y = 12, what is the minimum value of:
√(4 + x2) + √(9 + y2)
Suppose:
x2 = 17x + y y2 = x + 17y
If x ≠ y, what is √(x2 + y2 + 1) equal to?
For real numbers x, y, what is the minimum value of
√((x – 4)2 + (y – 10)2) + √((x – 44)2 + (y – 19)2)
