OK, I just did all of the functions in the problem. Did you try it already? What answer did you get? I want you to try it before you look at the answer. The answer that I got is:
Spoiler:
(x^2 + y) / y(x + 1)
I did the addition in both the top and bottom first, and I ended up with (x^2 + y / xy) / (x+1 / y). Then I multiplied both the numerator and denominator by the reciprocal of (y+1 / x), which is (x/y+1). This gives you a 1 in the demoninator and you are left with this equation (x^3 + xy) / (x^2 y + xy) Then I simplified it: x(x^2 + y) / xy (x + 1). Then the xes cancel, and you're left with (x^2 + y) / y(x + 1).
the x^2 is x squared. I didn't know how else to put it. I don't know if I did what the directions asked, since you didn't actually post the directions. Let me know if I did it wrong, which I very likely did. _________________

Sorry. Should of gave directions.. Here they are..
Simplify each complex rational expression by the method of your choice.
I got..
y^2 + 2 / y(y +1)
I think I remember the instructor saying something about dividing all fractions by the LCD. So.. If I am correct then it would be this.. I'm assuming that the LCD of x,y,x,and x would be.. xy. Hmm.. I can ask my teacher tomorrow and get back to you guys.. I have to get off line right now because of school tomorrow. Thank you for the help once again..
EDIT: hmm. .our answers were close. I will have get the answer tomorrow. _________________

When you have a fraction in both the numerator and the denominator, then you are supposed to miltuply both the numerator and the denominator by the reciprocal of the denominator. That I am sure of.
After reading the instruction, I'm almost positive that I did it right. Just out of curiosity, how did you come to your answer? _________________

Our answers were both wrong..lol I asked my professor today this is how he said to do it.
The answer was.. x^2 +y / y(y+1)
Hmm.. hard to explain on here..
You take y divide that by xy the Y's cancel each other out. .and your left with x times x which would be x^2.
Next you would take x divided by xy. the X's cancel each other out. Then you take y and multiply that by 1.. your left with Y.
You do the same to the last to fractions..
You take x divided by xy.. the x cancels each other out. and your left with y^2.
next you take x divided by xy.. the x's cancel each other out.. and your left with 1times y. witch would be y.
Your answer so far would be.. x^2 + y / y^2+y..
the last step is to simplify or factor if you can.. and you can factor the second one.. witch will then turn into. y(y+1).
Final answer.. x^2 +y / y(y+1)..
(Does that make sense.. I dont know how else to explain it..) _________________

^ Do you know what I did wrong. When I did the addition at the beginning, I made one of my y's look like an x, and that was why I got x^2 on the bottom unstead of y^2. I multiplied X+1 into the demonminator instead of y+1 all because my penmanship sucks. I didn't even catch it when I checked the problem over last night.
I don't understand the process that he told you, though. My way makes much more sense. _________________

ugh! i hate it! my article is so stupid! i wish i could ask for help but i couldnt since its about phil cuisine _________________

ok woot woot math time im in desperate need of help.
ok we are doing Quadratic Models In Real-Life, so its like quadratic formulas & stuff.
The height of an object thrown upward w/ velocity v ft per sec is given by h = -16t^2 + vt , where t is the time measured in seconds. If an object is thrown upward w/ a velocity of 100 ft/sec from ground level [h=0], how long will it take to return to ground level?
I have 0 = -16t^2 +100t so far. _________________ "If I hadn't met you, I wouldn't like you.

(might wanna put that 6.25 into a fraction tho) _________________

I hate it when they tell us how far we came to be as if our peoples history started with slavery
The height of an object thrown upward w/ velocity v ft per sec is given by h = -16t^2 + vt , where t is the time measured in seconds. If an object is thrown upward w/ a velocity of 100 ft/sec from ground level [h=0], how long will it take to return to ground level?
I changed t to the power of two, to just (t x t) so it would be easier in the long run:
0 = -16(txt) + 100t
16(txt) = 100t [minus the - 16(txt) from both sides]
16t = 100 [divide both sides by t]
t = 6.25 [divide both sides by 16]
Therefore, it will take 6.25 seconds to return to ground level.
