Question

\[\left\{\begin{array}{ll}x^2+f(y)^2=2.5\\y^2+f(x)^2=0.5\end{array}\right.\]
Where \(f(x)=x-\lfloor x\rfloor\)

Answer 1

Are we solving for x and y?

Answer 2

Yes :)

Answer 3

Show me your best guess. It seems like you just have to plug and chug here.

Answer 4

In case you're asking for the answers:
(1.5,0.5), (1.5,-0.5), (-1.5,-0.5), (-1.5,0.5), (-1.3,-0.1)

Answer 5

I mean, heck, if this is multiple choice you might as well just plug these in and work it backwards to save time. But I'm not asking for answers, I'm asking you to answer.

Answer 6

This is not multiple choice, I have the answers...

Answer 7

So what do you want from me? Show me an attempt at solving this, and I'll help you out. I can't help if you don't try.
