Let h = the hours worked in a week....and we have

2h + 15 = 3h - 15   add 15 to both sides, subtract 2h from both sides

30 = h

She worked 30 hours each week

-(4(-10)+1)

- [ 4 * -10   + 1  ] =

- [ -40  + 1 ] =

- [ -39 ]=

39

5y+4=4y+5    subtract 4, 4y  from both sides

y = 1    

That was pretty easy, huh???

I assume you want to graph this???

If so....notice that when x = 0, y = 3

And when y = 0, x = 12

So....we have the two points   (0, 3) and (12, 0)

Plot these on a graph..........connect them with a line.......voila  !!!!!  ........there's your graph  !!!!

2+6x=1-x      add x to both sides........subtract 2 from both sides

7x = -1         divide both sides by 7

x = -1/7

I don't think you can....however.....the calculator can be set to either degree or radian mode at the bottom left......!!!!!

So Im sorry but Im a bit confused with your answer 

A. would be : 403.4287934927351226,

B . 1 

C. 0.3678794411714423

Right ? 

e ^{-x + 4}   for  x =

 [-2 , 4 , 5 ]   = [e^6, 1, 1/e]  =  [403.4287934927351226,  1,  0.3678794411714423 ] 

It would be nice if you gave an example of what you are trying to do.

LOL!!!....NO, THEY ARE NOT !!!!!.......they are Melody's mis-matched "leggings"......!!!!!!

Just divide the price by the number of bagels in both cases and then compare "price per bagel".

Here's a fast way to determine this....compare....

3.29 / 6    and    4.15 / 8

Whichever ends up being smaller is the better deal.....!!!

How about: 1, 2, 4, 5, 10, 20, 25, 50, 100!!

Your scale shrinks the size of the Sun to 10 meters or about 33 feet, which is approx. the size of school bus!!!.

Don't fret. They are just CPhill's smelly socks.   @@^$#@@

Guest 8      Ahhhhh......sorry.  I didn't see the other answers before I posted .   I see your explanation of why my answer is WRONG  and it makes perfect sense '2C' it now.......   ha

Alan: I plugged it into "WolframAlpha" engine!!. This is the result it gives. I'm not very good at Integral Calculus, so I cannot judge if the two are the same or not. They certainly look different:

If you cannot see the above link, here is their answer:1/(2 (A^2+B^2)^3)

Very nice, Alan....!!!!

This is the same as Melody's first answer Guest.  Good try, but unfortunately it isn't correct - see my first reply above to see why.

Area of the square :  2 x 2  = 4

Area of Big arc = 1/4 pi 2^2 = pi

Area of small arc = 1/4 pi 1^2 = 1/4 pi

Area OUTSIDE of Small arc = 4 - 1/4 pi

Area OUTSIDE of Big arc = 4 - pi

Add the two outside areas and subtract the square area

4-1/4pi + 4 - pi -4 = 4 - 5/4 pi = ,073 Square units

You're welcome!

That was fantastic! Thank you! :)
