The U.S. Bureau of the Census predicted that the population of Pennsylvania would be about 12.7 million in 2010 and then would increase by about 0.24 million per year until 2018. Which of the following models predicts the population, y, of Pennsylvania (in millions) in terms of x, the number of years since 2010. y = 0.24x + 12.7 y = -12.7x + 0.24 y = -0.24x + 12.7 y = 12.7x + 0.24
since you start with 12. 7 and gain .24 each year, you would multiply the years by. 24 and just add the 12. 7 I hope this makes sense. also I love your profile picture :)
