Step-by-step explanation:
two points where the line goes through is (5,-4) as mentioned and (0,-16)
The top answer is correct.
Answer:17,544,511
Step-by-step explanation: 5929 x 2959= 17,543,911
17,543,911-300= 17,543,611
17,543,611 + 900 = 17,544,511
Answer:
271
Step-by-step explanation:
4 hours and 31 minutes = 240 + 31 = 271 minutes
Let x = number of years between 1990 and 2000.
Rainbow smelt:
Initial population = 227
Average yearly rate of change = -19.76
The linear function that models the population is
y₁ = 227 - 19.76x
Bloater fish
Initial population = 1052
Average yearly rate of change = -92.57
The linear function that models the population is
y₂ = 1052 - 92.57x
When the two populations are equal, then y₁ = y₂.
That is
227 - 19.76x = 1052 - 92.57x
(92.57 - 19.76)x = 1052 - 227
72.81x = 825
x = 11.33 years
= 11 years, 0.33*12 months
= 11 years, 4 months
Add x to 1990 to obtain the year April 2011.
Answer:
x = 11.33 years.
This occurs in April 2001.
