Length: 2x-1, width: x

A=LW

120=x(2x-1) 120=2x^2-x 0=2x^2-x-120, Factor (x-8)(2x+15)=0

x=8 is the width and 15 is the length

What is the rate of change of y=-4/9x+5

WARRIOR [948]

Answer:

Rate of change of y is $- \frac{4}{9}$

Step-by-step explanation:

$y = - \frac{4}{9} x + 5 \\ \\ differentiating \: with \: respect \: to \: x \\ \\ \frac{dy}{dx} = - \frac{4}{9} \frac{d}{dx} x + \frac{d}{dx} 5 \\ \\ \frac{dy}{dx} = - \frac{4}{9} .1 + 0 \\ \\ \huge \red{\frac{dy}{dx} = - \frac{4}{9} } \\ \\ rate \: of \: change \: of \: y =- \frac{4}{9}$

HURRY QUICK!!! Find the solution set of the inequality.<br><br>8x - 8 < ( or equal to ) -72

slava [35]

I would take away the 8's, and that would leave x standing, so X could either be -72 or less than -72,

Find dy/dx <br>2^(xy) = x^2

Dovator [93]

$2^{xy}=x^2$
$e^{\ln2^{xy}}=x^2$
$e^{xy\ln2}=x^2$

Differentiate, using the chain rule on the left side:

$\dfrac{\mathrm d}{\mathrm dx}[e^{xy\ln2}]=\dfrac{\mathrm d}{\mathrm dx}[x^2]$
$e^{xy\ln2}\dfrac{\mathrm d}{\mathrm dx}[xy\ln2]=2x$
$e^{xy\ln2}\left(x\ln2\dfrac{\mathrm dy}{\mathrm dx}+y\ln2\right)=2x$
$x\ln2\dfrac{\mathrm dy}{\mathrm dx}+y\ln2=2xe^{-xy\ln2}$
$x\dfrac{\mathrm dy}{\mathrm dx}+y=\dfrac{2^{xy+1}}{\ln2}$
$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac1x\left(\dfrac{2^{xy+1}}{\ln2}-y\right)$
