wow it didn't even show up in my list, weird

anonymous · Answer

i just saw your post on top and decided to check it

anonymous · Answer

yes thats what i was about to say. so its not just me

anonymous · Answer

i want to fan you but it wont let me XD

anonymous · Answer

probably one of their servers running the module fails a lot or something, probably not enough capacity to handle all the requests, i don't know.

anonymous · Answer

you can always fan me later

anonymous · Answer

true

anonymous · Answer

anyways is that question clear? or should i try and rephrase it better?

anonymous · Answer

i only have 69 fans but sometimes it feels like i have thousands, sometimes when i am just barely online my whole notification bar is getting filled with tags and i can't even keep up, not even if i help 3 people at the same time.

anonymous · Answer

yea and i noticed you have 69 fans :p

anonymous · Answer

no it's clear, he was probably asking you a question to help you guide you through the problem.

anonymous · Answer

i guess he meant, do you know what a ratio is?

anonymous · Answer

yea i went to answer and my entire browser almost crashed

anonymous · Answer

alright, but can you answer without crashing now? xD

anonymous · Answer

this is what i have also i just crashed again haha
(x^2 + x - 12)/(9 - x^2)

((x+4)(x-3))/((3 - x)(3 + x))

((x+4)(x-3))/(-(x - 3)(x + 3))

-(x+4)/(x+3)

anonymous · Answer

well, the equation is technically correct but the ratio is the other way around

anonymous · Answer

ratio a to b means a/b

and you did b/a

anonymous · Answer

wait what did i do

anonymous · Answer

well, they asked a divided by b, and you did b divided by a

anonymous · Answer

but your equation is still correct, so all you need to do is flip it.

-(x+4) / (x+3) makes
-(x+3) / (x+4)

anonymous · Answer

oh oops

anonymous · Answer

other than that you didn't even need my help, lol

anonymous · Answer

haha i just wanted to make sure i did it right and good thing i did :D

mertsj · Answer

After you write the ratio, you should factor and reduce the fraction.

anonymous · Answer

he did that, didn't he?
