Answer:
Step-by-step explanation:
We can directly substitute y of the first equation to the second equation.
-2x - 1 = 3x - 16
5x = 15
x = 3
Substituting back to any of the two equations, we get y = -2(3)-1 = -7. If you check with the second equation, y = 3(3)-16 = -7 as well.
Therefore .
Answer:
Step-by-step explanation:
Given
-- Initial population
--- Rate
Required
Determine the population in 8 years
The question shows an exponential distribution and the final population will be calculated using:
Where x is the number of years.
So, we have:
Convert % to decimal
(b) is correct
