Answer:
y2 = - 92.57x + 1052 ;
11.331 years
Step-by-step explanation:
Given that :
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 boater fish is :
Rate of change, slope = - 92.57 ; initial population, intercept = 1052
Representing the equation in the form ;
y = bx + c
b = slope or rate of change ; c = intercept
y2 = - 92.57x + 1052
To express equality :
y1 = y2
- 19.76x + 227 = - 92.57x + 1052
Collect like terms :
-19.76x + 92.57x = 1052 - 227
72.81x = 825
x = 825 / 72.81
x = 11.331 years
