the number N of state and federal inmates in millions during year x, where x greater than or equal to 2002 can be approximated by the following formula.
N=0.05x-98.45
Determine the tear in which there were 1.7 million

  • algebra -

    you just plug in 1.7 for N and isolate the x to get the year
    1.7mil= 0.05x - 98.45 its simple algebraic manipulation. you move 98.45 to other side by adding it to both side leavign you with

    1.7 mil + 98.45= 0.05x and then divide both side by 0.05 to get x by itself imma assume 98.45 is millions or else this formula makes no sense to me
