it has been found that the world record for the men's 10,000 meter run has been decreasing steadily since 1950. the record is approximately 28.7 minutes minus 0.05 times the number of years since 1950. assume the record continues to decrease in this way. predict what it will be in 2010.

  • algebra -

    28.7-(.05*60)

  • algebra -

    t = 28.7 - 0.05(year -1950)
    t = 28.7 - (0.05)(60) yes
