    Dy/dx = xe^(y-2x) , form differntial eqaution?

    dy/dx = xe^(y-2x) , i am asked to form differential equation using this equation . the ans given is (e^-y) = 0.5(e^-2x)(x+0.5) + a , how to get the answer? btw , i have attached my working . I have tried it many times , but still cant get the answer

    berounilli eqaution suitable ?

    is it suitable to use berounilli eqaution for dy/dx + (y/x) = y^6 ? but , according to the notes i posted , the eqaution must have q(x) , unfortunealy , in the dy/dx + (y/x) = y^6 , there is no q(x)

    log eqaution from a graph

    hi; I'm having trouble finding the log equation from its graph, I'm given two points (-1,-3) and (2,-1) I know the equation is f(x) = logb(x + 2) - 3 and I know from this that the asymptote = -2. struggaling to find values a, b and c.Thanks for the help.

    exponetial eqaution

    Hi, I have some equation that I am having trouble solving. (1) 2(2^{2x})-5(2^x)+2=0 must find x (2) 4^x-6(2^x)-16=0 (3)3^{2x+1} -26(3^x)-9=0 Must also find x for both of them. and I also tried this one and came up with the answer y=1 (4)\log_{2}x+\log_{x}2=2 I have to ind x Can anyone...
