inequalityFor y and x we have this : x(x15) + y(y10) + 78 <= 0; Find the max and the min value of the expression : 3x + 2y. Humankind's inherent sense of right and wrong cannot be biologically explained. #2 20060105 01:57:55
Re: inequalityFirst, take the equation: "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #3 20060105 02:07:32
