Question 936464: Solve for x and y:
x^2 + y^2 = 17
y-1=x
There are two solutions: (x1, y1) and (x2, y2)
Evaluate: x1+y1+x2+y2=
A. 2 sqrt19
B. 0
C. -2-2 sqrt19
D. 2
E. none of these
(from there are two solutions and the evaulate problem under it, the x1, y1 and x2, y2 are all not exponents but logs)
