The number of incarcared to measured in thousanda) in a certain country can be approximated by the couton N=-4.6x^2+ 70.6x+ 1965, where is the number of years since 2000. In 2007, the number of incarcerated adults peaked. how many adults were incarcerated in that year ?
There were___ incarcerated adults in 2007

There were 2,233,800 incarcerated adults in 2007

Number of incarcerated adults:

The number of incarcerated adults in x years after 2000, in thousands, is given by:

How many in 2007?

2007 - 2000 = 7, so this is N(7).

2233.8*1000 = 2,233,800

There were 2,233,800 incarcerated adults in 2007

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
