Answer:
For this case we know that at the starting year 2000 the population was 9 billion and we also know that increasing with a double time of 20 years so we can set up the following model:
And if we solve for b we got:
And then the model would be:
Where y is on billions and t the time in years since 2000.
And for this equation is possible to find the population any year after 2000

Answer:
Step-by-step explanation:
-2x - 14 > -4 + 3x
subtract 3x from both sides
-5x - 14 > -4
add 14 to both sides
-5x > 10
divide both sides by -5
x < -2
