Output = n + 4
Each will get 2 and three will remain... (if you count yourself in the group of 5)
Hey Chris ! Welcome back to 'here' ....
*** edit **** typo fixed
Simple interest would be 20 000 (.075)(48) + 20000
....and here is an error 4(3x-5)/2(x+3) = 2 (3x-5) / (x+3) ( you dropped the denominator by accident)
= x^2 + 16x -5 bowl shaped parabola, min will occur at x = - b/2a = -16/(2*1) = - 8 , sub in '-8' for x to find the minumum value of -69
There are 8 possibilities
only ONE ( T T T ) has no 'HEADS'
so 7/ 8 have at leat ONE head
Divide the second term by 2/2 to get
[(8x-4) - (6x-10) ] / ( x+3) =
(2x +6) / (x+3)
2 (x+3) / (x+3) = 2
Compounded annually would be 20 000 ( 1 + .075)48
Simple interest would be 20 000 (.017)(48) + 20000
(-2 , 0) and (-3 , 0)
a(x+2) * (x+3) = y
a(x^2 + 5x + 6) = y sub in given point
a(25 + 25 + 6) = 10
a = 10 / 56 = 5/ 28
y = 5/28 x^2 + 25/28 x + 30 / 28
