Preston and Joel are both solving the equation 2x=14. Preston is not sure what to do because he does not know a power of 2 that
Murrr4er [49]

Answer:

  yes

Step-by-step explanation:

You can always separate an equation into two parts and see where those graphs intersect.

Joel's method works well.

_____

<em>Additional comments</em>

Preston should know that the invention of logarithms makes it easy to solve equations like this. x = log₂(14) = log(14)/log(2) ≈ 3.8073549.

As for Joel's method, I prefer to subtract the right side to get the equation ...

  2^x -14 = 0

Then graphing y = 2^x -14, I look for the x-intercept. Most graphing calculators make it easy to find x- and y-intercepts. Not all make it easy to find points of intersection between different curves.

I don't really understand pls help asap
maria [59]

Answer:

It is not proportional

Step-by-step explanation:

    To figure out if something is proportional they have to equal the same thing.

   As you can see on the problem 0.2 and 0.2 are the same thing, and since one is on the numerator and one is on the demoninator those two can cross out.

    Now we come to the 0.08 and the 0.8.

     They are not the same thing the 0.08 has an extra 0.

So this is not proportional
