Question

Please HELPPPP.

It isn’t hard I forgot this answer

Answer 1

$\bf \qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\underline{y} varies inversely with cube of \underline{x}}}{y=\cfrac{k}{x^3}} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\underline{y} varies directly with square of \underline{x}}}{y=kx^2}$

Answer 2

Answer:

Step-by-step explanation:

#11a

y = k/(x³)     y varies inversely with the cube of x

#11b

y = kx²     y varies directly with the square of x
