If the average rate of change of g(x) from x = 7 to x = 10 is -80, and if g(7) = 400, then find g(10).

  • college algebra -

    g(10)=460

  • college algebra -

    using y=mx+b
    m= -80
    substitute the info given, g(7)=400
    400 = -80(7) + b
    b=960
    substitute m & b into the equation;
    g(x)= -80x + 960
    substitute g(10) into the new equation
    g(10)= -80(10)+960
    g(10)= 160
    SORRY, ABOUT THE LAST POST :)

  • college algebra -

    So you have 2 points, (7,400) and (10-7) = -80
    ,y) where the slope = -80

    (y-400)/(10-7) = -80
    y-400 = -240
    y = 160 , or g(10) = -240
