    Proof that LHS coefficients have to = RHS coefficients

    Yes I meant for all x≠y. Thanks for your help.

    Proof that LHS coefficients have to = RHS coefficients

    Sorry, x and y are just real numbers. Such as -12.12, 20, 5080.892, etc. This is not of the form (a)x + (b)y = (c)x + (d)y Unfortunately I still don't see what's wrong with the matrix that I typed up. Not that you're wrong, I just can't understand what you're saying because my maths...

    Proof that LHS coefficients have to = RHS coefficients

    Hey everyone. Thanks for so much help on this question. I need to prove this as part of a broader question in an assignment on utility theory. The equation is this; aE[u(x)] + (1-a)E[u(y)] = (b+(1-b)a)E[u(x)] + (1-b-(1-b)a)E[u(y)] (1) Both sides are a gamble, E[u(G(x,y;a))] =...

    Proof that LHS coefficients have to = RHS coefficients

    Hi, thank you for your suggestion. Are you sure that this is a proof? I'm not sure; [x y] = [x y], hence [a b] = [c d], hence a=c, b=dI mean it makes complete sense but it's a part of a much longer proof for an assignment so it's important that it's correct

    Proof that LHS coefficients have to = RHS coefficients

    Homework Statement If; a*x + b*y = c*x + d*y x ≠ y a,b,c,d ≥ 0 Prove that; a=c b=d 2. The attempt at a solution I've been fiddling with this equation and have been getting nowhere.

    Is this the lamest news article ever?

    I don't empathize with the view that this is crap news. I found it very interesting.. wish more news was like this.

    Medical MRI Mind Reading claim (newspaper)

    Why are the images all fuzzy :s Why can't they just pull up the actual image that they're guessing why do they have to "recreate" it? Thanks.

    Who Benefited from the Housing Bubble?

    Mortgage brokers (the actual employees w/ limited liability) who were earning stupid commissions and those firms constructing and selling the original non-conforming retail mortgage backed securities without holding too much of them. Real estate agents maybe? (as someone above suggested)

    What U.S. Economic Recovery? Five Destructive Myths

    From the quotation in the OP: I'm not sure what information this reporter was trying to convey when adding this sentence in during a discussion about youth unemployment. Those unemployed are unemployed partly because they're the most undesirable to the labour market (on average) in...

    Near-Death Experience: Investigating Theoretical Implications

    I've done reading on this topic for about a year, a few years ago. Forgot most of the papers that I read. I recall the most interesting result from different studies being the claimed veridicality of NDEs.. Some cases seemed quite remarkable. Unfortunately I don't remember many references as it...

    Solution to paid parental leave badness- economic crackpot or makes sense?

    Was thinking about the paid parental leave schemes. I have come under the impression that they are unfair (unfair under any system) as they stand now. The fact that it exists forces profit maximising firms to give lower wages to women - they incur a risk premium. This is because women, from...

    Is Economics Really Just a Guess?

    Even if a million people started speculating on real estate, that doesn't mean that there will be any irrational decision making on behalf of the market participants (irrational under the economics definition). ]
