Where they intercept, they will obviously be equal....so set them equal to each other:

5x-6 = 4x + 10

x = 16                  then sub this value of 'x' to find 'y'

y = 5(16) -6  = 74       x,y = 10,74

Nicely done, Max !  Thanx !

Not sure how to prove it, but just by looking at it 'a' is 3/2 pi

Yah.....it is a pain.    Hope they ' fix ' it ...you have my vote!

OK...you should ask that the DEFAULT value of 25 be changed to a default of 100 for ALL users.....Good luck....sounds like a good idea to me!

This question has been posted and answered on here about a 'buh-jillion' times.   Not sure why...it is kind of stupid.....Maybe YOU think it is funny, I guess....

Anyway: What do YOU think the answer is????

LOTS and lots of choices here

how about     3 x 4 x5 

Pick one

APR = 12%

compounded quarterly (every three months)    Periodic interest =  12/4 = 3% = .03 = i

APY = (1+i)^n       where n=periods in a year (4)

APY = 1- (1.03)^4 = .1255    =  12.55 Percent

Which shows that compounding will effectively raise the APR     MORE frequent compounding will raise it even more!  

It doesn't:

(x-y)(x+y)       Use distributive property

x^2 + xy  - xy - y^2

=x^2 - y^2
