4x-6= x+6
4x= x + 12
5x= 12
X= 12/5
X= 2.5
The population starts at 2000, so a=2000.
We also know that the population in 3 hours is 1000, so we can setup the equation:
2000 b^3 = 1000
This gets us:
b^3 = 1/2
And taking the cube root of both sides gives us:
b ≈ 0.7937005259841
Rounding that to 4 places, we have:
f(t) = 2000 (0.7937)^t
Answer:
-3
Step-by-step explanation:
It would just be -12+9=-3.
