Answer:

s = 6

Step-by-step explanation:

Given: -2s + 8(9 - s) = 3 - (9 - 3s)

Get rid of the brackets by using the distributive property:

-2s + 72 - 8s = 3 - 9 + 3s

You can rearrange the items so the expression is easier to solve:

-2s - 8s + 72 = 3s + 3 - 9

Combine like terms:

-10s + 72 = 3s - 6

Now let's subtract 72 from both sides of the expression:

-10s = 3s - 78

Next, subtract 3s from both sides of the expression:

-13s = -78

Lastly, divide each side of the expression by -13 to get:

s = 6

Hope this helped!

Differentiate x^2 e^x logx
zimovet [89]

Product rule:

\dfrac{\mathrm d}{\mathrm dx}(x^2e^x\log x)

=\dfrac{\mathrm d(x^2)}{\mathrm dx}e^x\log x+x^2\dfrac{\mathrm d(e^x)}{\mathrm dx}\log x+x^2e^x\dfrac{\mathrm d(\log x)}{\mathrm dx}

Power rule:

\dfrac{\mathrm d(x^2)}{\mathrm dx}=2x

The exponential function is its own derivative:

\dfrac{\mathrm d(e^x)}{\mathrm dx}=e^x

Assuming the base of \log x is e, its derivative is

\dfrac{\mathrm d(\log x)}{\mathrm dx}=\dfrac1x

But if you mean a logarithm of arbitrary base b, we have

y=\log_bx\implies x=b^y=e^{y\ln b}\implies1=e^{y\ln b}\ln b\dfrac{\mathrm dy}{\mathrm dx}

\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{e^{-y\ln b}}{\ln b}=\dfrac1{b^y\ln b}

\implies\dfrac{\mathrm d(\log_bx)}{\mathrm dx}=\dfrac1{x\ln b}

So we end up with

2xe^x\log x+x^2e^x\log x+\dfrac{x^2e^x}x

=xe^x(2\log x+x\log x+1)
