Question 174619: hows it going recently i have begun getting myself evrolled for school and going over math i havent done in 3 or so years so i picked up an algebra review book but nither it nor the internet has shown me how to do the following three equations. im hoping someone can help me.
y=(x-2)^2+1
2) x/3+y/5=2
3) 3/x-2=y+4/2
i appriciate any help recived Found 2 solutions by Alan3354, Mathtut:Answer by Alan3354(69443) (Show Source):

----------------
You didn't say what you want to do. Often, it's "solve for x", so I'll do that. It would be better if you specified, tho, and not waste my time and yours.
-----------------
y=(x-2)^2+1
(x-2)^2 = y-1
x-2 = sqrt(y-1)
---------------------
x/3+y/5=2
Multiply thru by 15 to eliminate fractions
5x + 3y = 30
5x = 30-3y
x = (30-3y)/5
----------------
3/x-2=y+4/2
Do you mean 3/(x-2) = (y+4)/2 ? It could (3/x)-2 = y+(4/2) I'll assume the 1st.
3/(x-2) = (y+4)/2
With 2 fractions, the quickest way is to "cross multiply", the NUM of one times the DEN of the other.
3*2 = (x-2)*(y+4)
6/(y+4) = x-2
x = 2 + (6/(y+4)) Notice how the parentheses eliminate any ambiguities. And they're free.
You can put this solution on YOUR website! 1. it is a parabola written in vertex form
:
2. subtract -x/3 from both sides multiplied all terms by 5
:
3.3/x-2=y+4/2
please rewrite this problem. remembering to put parenthesis where they need to be...this reads 3 divided by x minus 2 and y plus 4 divided by 2. which is probably not what you intended....remember the order of operations....parenthesis then mult. and div left to right then addition and subtraction left to right.
