say X is equal to
1 3 3
1 3 4
1 4 3
and Y is equal to
7 -3 a
b 0 1

There are alot of idiots out there who claim that they know alot about a subject matter while in fact they practically know nothing... Worst part about it, they sometimes distribute their wrong information or knowlegde to other people as well.. My question is how are we to know whether the person who gives us the information are reliable or not??

I just started caring for my uncle Jack. He was being mistreated at a board and care facility. His feet are a purple color. Is this an indicator of something I can help fix? We are on our way to the doctor soon, but is there anything to do in the mean time?

Ive known this girl since december, we have been good friends. Since school started on feb 5th, nearly everyday i have been buying her lunch as well as for myself. I always felt that she liked me and we would have something.
But today during school class, one friend told me that the girl said to her she doesnt like me about a month ago.

I cried during lunch time, i wanted to tell her that i knew she didnt like me, but when she came up to me, i was afraid to say it. I still have her in my heart, i like/love her a lot, but if she doesnt like me then i duno wat to do. If i told her, i would probably cry in front of her. Maybe tomorrow i will feel stronger. But i really dont want to lose the friendship we have. I also dont want to buy her lunch almost everyday now, if she asks me to get her lunch, wat should i say? Wat should i do about this friendship?

Someone I know has a revolver for sale which they purchased from someone who had purchased it at a gun show. They did not go through a dealer, but was "told" the revolver was legal, and not stolen. I intend to do a legal transfer through an FFL Dealer, but I want to make sure the revolver isn't stolen before proceeding with a transfer. Usually, the seller isn't scrutinized like the buyer, unless the firearm is stolen. I'd just rather not open up a can of worms for the seller, since he bought it in good faith, I'm just looking to score on a good price.

Thanks in advance.
