The number is 4/5 or 0.8.

let x be the number.

12 - 2x = 8x + 4

-12 -8x   -8x   -4

-10x = -8

-10x\-10 = -8/-10

The number of camera phones shipped globally can be modeled by the function y=1.28e^1.31x where x is the number of years since 1
erik [133]
The first thing you should know for this case is how many years there are from 1997 to 2014.
 The number of years is:
 x = 2014-1997 = 17
 Then, you must replace this value in the given equation:
 y = 1.28e ^ 1.31x
 y = 1.28 * e ^ (1.31 * (17))
 y = 6011018736
 answer:
 the number of camera phones shipped in millions in 2014 is
 y = 6011018736

Then you can divide by (29 -10) to get
.. sum of numbers = 133/19 = 7
