Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> In 2x - In(3x - 1) = 0
LenKa [72]

Answer:

\frac{-1}{3x^2-x}

Step-by-step explanation:

  1. If f(x) is in th form of f(x)=g(x)-h(x) then f'(x)=g'(x) - h'(x)
  2. When f(x)=z(g(x)) then f'(x)= z'(g(x))g'(x) (called as chain rule)

<u>using these information</u>:

g(x)=ln2x then g'(x)=\frac{(2x)'}{2x} =\frac{2}{2x}=\frac{1}{x}

h(x)=In(3x - 1) then h'(x)=\frac{(3x-1)'}{3x-1} =\frac{3}{3x-1}f'(x)=g'(x) - h'(x) =[tex]\frac{1}{x} - \frac{3}{3x-1} =\frac{-1}{3x^2-x}

What is the answer for 2,4,6.....please show work and need answer asap.....thank you
sashaice [31]
You've been working with rectangular prisms all night, and the same formula gives the volume of every one of them.  Unfortunately, you used way more time asking other people for answers than it would take you to solve them on your own.

The formula is:

             Volume  =  (length)  times  (width)  times  (height) .

With that formula, you can directly solve problems #1, #2, #3,
#4, and #8.  It's also the only math you really need to solve #9 ...
but you also need to use your brain cells for #9.


For #6, start with the same formula:

                                     Volume = (length) x (width) x (height)

Divide each side by
(width) x (height), and
then it says:               Length = (volume) / (width x height) .

#6 gives you the volume, width and height. 
 You can just write them into this equation,
and bada-bing, you'll have the missing length.
