the population of a city increases by 4,000 people each year. in 2025, the population is projected to be 450,000 people. what is and equation that gives the city's population p (in thousands of people)
x years after 2010?
Let's assume that x represents the number of years after 2010.
Since the population increases by 4,000 people each year, this means that it increases by 4 people (4,000/1,000) in thousands of people.
To find the equation that gives the city's population p in thousands of people, x years after 2010, you can subtract the initial population in 2010, which is 0 (assuming there are no people before 2010), and then multiply it by 4. Finally, you sum it with the initial population in 2010.
Therefore, the equation is:
p = 4x + 0
Or simply:
p = 4x
