Question

The linear function that models the population of rainbow smelt is y1 = −19.76x + 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 ✔ –19.76x + 227 = –92.57x + 1052 . The solution is x = years.

I got it right on edge heres a pic of the answers [:

Answer 2

The linear function that models the population of bloater fish is y2= -92.57x + 1, 052

The linear equation that determines when the two populations were equal is

-19.76x + 227 = -92.57x + 1052

The solution is x= 11.33 years
