Suppose:
x2 = 17x + y y2 = x + 17y
If x ≠ y, what is √(x2 + y2 + 1) equal to?
The line 2x – y + 1 = 0 intersects the curve x2 + 3y = 19 at the points A and B. The perpendicular bisector of AB intersects the x-axis at the point C. Find the area of triangle ABC.
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)
