Solve for n: −np − 3 ≥ 7(c − 4)

The first thing you need to do is distribute the 7 into the set of parenthesis on the right.  That will give you -np-3 \geq 7c-28.  Then add 3 to both sides: -np \geq 7c-25.  Divide both sides by p to get -n \geq  \frac{7c-25}{p}.  Now divide both sides by -1.  This is where the sign of inequality is going to change direction.  That's why I saved it til last so we could make a point  of making sure it gets done.  n \leq -( \frac{7c-25}{p}) and if you distribute the negative in your solution is n \leq  \frac{-7c+25}{p}.  Or you could write the positive expression first, as many of us prefer: n \leq  \frac{25-7c}{p}.  There you go!

PLEASE HELP ASAP! DUE SOON PLEASE SHOW YOUR WORK
viktelen [127]

Answer:

So for the first one the first ting u have to do is FLIP the equation so---> X-12=y

Then you have to add 12 to BOTH sides----> x-12+12=y+12

<u><em>So your answer for X ----> x=y+12</em></u>

<u><em>For Y on the first equation it is--->y=x-12</em></u>      (Just flipped and the sign changed)

For the second equation we are gonna solve for Y first.

The first thing u want to do is divide both sides by -3 so it will look like this

-3y/-3    =   2x/+36/-3

<u><em>So Y will equal-----> -2/3x- 12</em></u>

Now we are going to do the X part

So fist FLIP the equation---->      2x+36=  -3y

The add -36 to both sides-----> 2x+36+-36=-3y+-36

Last step you have to divide both sides by 2

So that would be----> 2x/2= -3y-3

<u><em>Your final result will be----> x=-3/2y-18</em></u>

I hope this helped you out (:::::::

Can someone show me how to even start with 1 and 2? ​
diamong [38]

All you need to know is that

\displaystyle \lim_{x\to\infty}a^x=\begin{cases} \infty \text{ if } a>1\\1 \text{ if } a=1\\0 \text{ if } 0\leq a

So, the first function grows exponentially and the second decays exponentially. The rate of growth/decay are the bases of the exponentials, which means 1.08 and 0.205
