find all positive solutions of the system of equations:
A + B = C^2
B + C = D^2
C + D = E^2
D + E = A^2
E + A = B^2
anyone know how to solve this?
a function f: R -> R has the property that for any four real numbers a, b, c, d such that a - b > c - d, we have f(a) - f(b) > f(c) - f(d). prove that f is a linear function, ie f(x) = mx + n for all x belonging to R, where m, n belong to R and m > 0
Does anyone know the name of this theorom or how to prove it?!
