my professor used "the elimination method" to find the intersection of these lines. i didn't pay attention (It was an operations management course) but now i figure it will help me save time on the exam. can someone set this up for me and get the intersection of the line. i already know the answer (10,10) but not how he got it. if i don't get this, i'll have to use the long, drawn out formula.

line 1: 2x + y = 30
line 2: 2y + 2x = 30

Thanks for your help!

I ASKED THIS QUESTION EARLIER AND YOU GUYS POINTED OUT THAT THE LINES WERE PARALLEL. HERE ARE THE RIGHT ONES SO HOPEFULLY I CAN GET SOME HELP THIS TIME!

Trying to create a pricing model for homes in the tristate area. I haven't calculated the coefficients for the regression- but i was going to start with structure

price of house = a(house sq feet) + b(land acreage) - c(avg train commute to nyc) - d(pv of property taxes)

are there any other factors u think will have significant explanatory power? # of bathrooms, # of bedrooms, age of house, some sorta rating or score for school district quality (think this might be at least partly explained by property tax), etc. any suggestions?

the point of this is two fold- first i figure if i can create a high r2 regression- i can find which neighborhoods are over/undervalued. secondly i can determine how well a house is priced within that market.

i ain't exactly a mathmatician- so all comments are welcome.

Does it bother anyone else that billions of dollars are being spent on space exploration while we have loads of problems at home on Earth? Wouldn't it make sense to give NASA a rest for a few years to solve some worldly problems and then maybe worry about what the hell is in space?

I'm checking out some wilderness guides. I know the theory behind banking a fire--that you cover the coals in ashes, and this keeps them alive until morning. How long can you reasonably expect them to stay alive? Does the size of the coal matter before you bank it? How much ash should you put on? Any other advice?
