$\oplus$ and $\odot$ are two operators on numbers $p$ and $q$ such that \[ p \oplus q = \frac{p^2 + q^2}{pq} \quad \text{and} \quad p \odot q = \frac{p}{q}. \] If $x \oplus y = 2 \odot 2$, then $x = \ \underline{\hspace{2cm}}$.
The operators are defined as:
First, evaluate the right side of the equation:
$2 \odot 2 = \frac{2}{2} = 1$
The given condition is $x \oplus y = 1$. Substituting the definition:
$\frac{x^2 + y^2}{xy} = 1$
Assuming $x \neq 0$ and $y \neq 0$, multiply by $xy$ and rearrange:
$x^2 + y^2 = xy$
Rearranging the terms gives:
$x^2 - xy + y^2 = 0$
Based on the structure of the problem and the provided options, the answer corresponds to Option B.
Final Answer: The final answer is $\boxed{y}$
Given $f(x, y) = x^2 - 2xy + y^2$
The complete contour of the equation $f(x, y) = 1$ is described by the option(s) ___.
