subtract 5 from both sides:Originally Posted by Caycee7
now use the quadratic formula:
substitute:
simplify:
you can solve from there...
I start my Ap Cal class tomarrow and our summer homework included some problems I just cannot figure out, any help would be amazing!
~factor and simplify. express answer as a fraction withought neg. exponiets
x(9x-10)^-1/2 + 2(x-1)^1/2
~Another one is this... I thnk you may have to use compleating the squares but couldnt figure it out)
x^2-x=5

Okay I feel bad to keep posting questions but I have one that is asking me for the general form of a line passing through pint (3,1) slope=5/2
I thought this isnt bad and drew the graph but now I found out that that is a formula that I have never studied at all, I tried to read up on it on some other sites but got extreamly confused, and ideas?
it's a general form of a line, I don't think there is one specified "general form" (although y=mx+b would be most likely)Originally Posted by Caycee7

to answer your other question:
you are given the equation
therefore:
subtract 3 from both sides:
divide 2 from both sides:
Thanks everyone I finally finished all of my problems! Took a few hours but a relief to have it all finished. Now I am off to finish my English work, I have a feeling it is going to be a long night! Oh well that’s what I get for procrastinating. Thanks again, I'm sure I'll be around now that I found this site, I have AP both for Cal and Stats, and math isn’t my best subject...
