Does your teacher want you to simplify using a calculator or to simplify without using a calculator? Get back to us and we'll take it from there.

I have just answered a question on this same function when you posted as "009". Keep the same name please. In this case I will simplify the function a bit f(x) = 1/(1 + e^-x) = (1+e^-x)^-1 * e^x/e^x = e^x/(e^x + 1) f ' (x) = ( (e^x + 1)(e^x) - (e^x)(ex) )/(e^x + ...

math check
Simplify each rational expression. 3a(a-4)^2 over a^2(a-4) I don't understand how the answer would be 3(a-4) over a because the a-4 would cancel out??? 4-y^2 over y^2-2y once I simplify I get (2-y)(2+y) over (y-2)(y+2) I don't understand how the answer is -(y+2) over y...

Wow! Cheers. I'll look up on it. But, basically, there's no way to simplify that "equation" to something like x=... ? I was thinking along the lines of using Log, but I can't simplify log(2x-1) :( Again, cheers.

Use the quadratic formula to slove the equation. x^2-x=-7 This is what I have got so far and I do not think this is right: x=1(-1)±√-1^2-4(1)(7)/2(1) x=1±√1-4(7)/2 x=1±√-21/2 x=1±-21/2 and here I am lost! Use rational ...

i know how to do the majority of these type of questions, but i dont know how to simplify this one all the way.. 8(2x-1)^3= 125 i know you could go (2x-1)^3= 125/8 (2x-1)^3= (5/2)^3 but how can i simplify any further, and yes there is an answer.
