No, that is incorrect. The answer is B.
Im getting mixed signals...
there are infinite solutions
lol. since 4=4 i don't think there is infinite solutions
$$(x,y) = (1, 0)$$ is an answer.
as is $$(x,y)=(1/2, 2)$$.
nomothetis how did you get this ?
I am getting a little MORE confused... ^_^ lol so many diff answers!!
just try some (x,y) = (0.5, 2) is another solution
:P sorry i am retaking stuff from like the beginning of the year :P So then do u all agree with jimmy?
Here's how you prove that you have an infinite number of solutions: Can you make get equation 2 by multiplying equation 1 by something? Let's consider it: $$4x + y = 4$$ This is the same thing as: $$y = 4 - 4x$$ Since all we need to do is pass the x to the other side. So the two equations are really the same equation. So any points that is a solution for the first equation will work for the second equation. But if you look at the first equation, you see that it's the equation for a line. Therefore, any point on that line will be a solution to the second equation as well. This means that you have an infinite number of solutions.
oh nomo siad that one try (x,y) = (0.25,3) then!!!
Ok so its B?!?!?! are we positive on this answer now? lol
i don't agree since it clearly states that "solve by substitution"
B) is correct, even if you use substitution. The substitution gives 4=4 which means that the statement is always true for any (x,y) as long as (x,y) is on the line 4x+y=4.
right nomo - the 2 equations are the same and u can fit infinite values of x and corresponding values of y into the equation
ok i see. that makes sense watchmath
absolutely positively b !! lol
Okay!! haha finally!! (: lol
