I think it's A or E.
it is D
A and C works =0, so wouldnt it be many solutions
i thought so but then I looked up the definition of infinitely many solutions and it said that it meant tht u can never run out of possible solutions..so then I had second thoughts.
sorry how does C work, I think it is just A
D is not right
Lol, i think i am confusing you, yes C does work
yea u r kind of confusing me..u just named three answers. :) lol
that is tree lee, mmm im lost now lol
hahahaahha, am sorry. :D well when i trying susbtitution, I got the answer 3,0 i dont know how u can, get 1,-3, but when u plug it in then it is a solution. so i think is it infinite solutions.
i solved for x, and plug it into other equations- i got 0.. so no solution =0
I definitely know tht no solution is wrong but I think it is infinitely solution...So we r going to go with E.
i have a graphing calculator, i will solve the problem now. wait
i had calculation wrong, i change my answer to infinity lol
So is it D Luis?
(4.5,6) is another solution =0
we just have to wait for Sal to c if we r right.
ok it is E, system has infinite solutions, becuase in fact the two lines are the same, if you try and isolate for y, in both cases you will get the same line y=(-9+3x)/2. Hence, the two lines are on top of each other and they interesct at infinite points, this is how you have infinit solution.
yea i get now..thts wat I thought it was..but thnk u for checking.
same line?,, one has negative slope, and the other is positive....
let me check one more time
no, they are the same line. Try to isolate for y for both lines
yea they r the same line...he's right and so am I so we r going with E.
sry but i still dont get same line >.<
lol, the signs are confusing. i was checking like 3 times. try and get y on its own and everything to the right side.
by graphing wat i got for those equations... i got (3,0) as solutions now--- btw, u just solve for y in those 2 equation right ?
nvm 4th check, i got same line-- blame the SIGNs-- thanks
haha np :P
