$\bf C=\cfrac{5}{9}(F-32)~~
\begin{cases}
C=Celsius\\
F=Farenheit\\
-------\\
F=329
\end{cases}\implies C=\cfrac{5}{9}(329-32)
\\\\\\
C=\cfrac{5}{9}(297)\implies C=165$

<h3>Answer:</h3>

$\frac{1}{9}$

<h3>Step-by-step explanation:</h3>

We know that $x=-2$ , so substitute that into the equation. $y=3^{-2}$

With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking, $x^{-y}=\frac{1}{x^y}$ . This makes our equation: $y=\frac{1}{3^2}$
