The correct answer is 1.

So, circle the 0 after the equals sign because the equation does not equal 0.

Anything raised by the power of 0 is 1.

This is known as the zero exponent rule :)

If y varies inversely as x, and y=20 as x=3, find y for the x value 4

Ratling [72]

$\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\begin{cases}
y=20\\
x=3
\end{cases}\implies 20=\cfrac{k}{3}\implies 20\cdot 3=k\implies 60=k
\\\\\\
thus\qquad \boxed{y=\cfrac{60}{x}}\\\\
-------------------------------\\\\
now\qquad x=4\qquad y=\cfrac{60}{4}$
