The number of rainbow smelt in Lake Michigan had an average rate of change of β19.76 per year between 1990 and 2000. The bloater fish population had an average rate of change of β92.57 per year during the same time. If the initial population of rainbow smelt was 227 and the initial population of bloater fish was 1,052, after how many years were the two populations equal?
The linear function that models the population of rainbow smelt is y1 = β19.76x + 227, where
x = the years since 1990 and y1 = the number of rainbow smelt.
The linear function that models the population of bloater fish is y2 =
.
The linear equation that determines when the two populations were equal is
.
The solution is x =
years.
