the population of the city of Woodville is growing at a constant rate. The expression 38,000 +2, 400x models Woodville's population in x years from now. Which THREE statements are correct? 38,000 +2, 400x A x represents the number of years B 2,400 represents the current population. C 38,000 represents the current population. D 2,400 represents the population growth yearly. E 38,000 represents the population growth yearly.

1 answer

Let's analyze the expression \( 38,000 + 2,400x \) representing the population of Woodville.

  • The term \( 38,000 \) represents the current population.
  • The term \( 2,400x \) indicates that the population is increasing by \( 2,400 \) each year.

Now, let's evaluate the statements you've provided:

A. x represents the number of years.
True. In the expression, \( x \) is indeed the variable representing the number of years from now.

B. 2,400 represents the current population.
False. The \( 2,400 \) is not the current population; it represents the yearly increase.

C. 38,000 represents the current population.
True. The constant \( 38,000 \) is the initial population at year \( x = 0 \).

D. 2,400 represents the population growth yearly.
True. The coefficient \( 2,400 \) signifies that the population grows by \( 2,400 \) each year.

E. 38,000 represents the population growth yearly.
False. The \( 38,000 \) represents the current population, not the yearly growth.

Based on this analysis, the three correct statements are:

  • A: x represents the number of years.
  • C: 38,000 represents the current population.
  • D: 2,400 represents the population growth yearly.
