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 . The solution is x =

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.

Answers:

The linear function that models the population of bloater fish is y2 =  

–92.57x + 1,052 (D).

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

–19.76x + 227 = –92.57x + 1052.

The solution is x = 11.33 (D) years.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
