Answer 2

p = 4x + 450

Answer 3

i mean p = 4x + 390

Answer 4

btw i think the answer is C

Answer 5

In 2010, the population is p(0).
In 2011, 1 year after 2010, the population is p(0) + 4000 * 1
In 2012, 2 years after 2010, the population is p(0) + 4000 * 2
In year the year that is x years after 2010, what is the population?

Answer 6

i can tell the answer is C

Answer 7

Let's see if C is correct.
The year 2025 is 15 years after 2010, so x = 15.
C. p - 15 = 4(x - 450)
p - 15 = 4(15 - 450)
p - 15 = 4(-435)
p - 15 = -1740
p = -1,725
Since p is the population is thousands, using choice C, you get a population of -1,725,000 in 2025, but we are told the population in 2025 is 450,000, so choice C is not correct.

Answer 8

ohh good thing i know its not C because i was just gonna put that

Answer 9

Try each choice with x = 15, and find p.
The correct choice has to give you a value of p of 450,000.

Answer 10

Of course, we can also figure out what the correct answer is by figuring out the equation ourselves.

Answer 11

the only possible answer it could be is out of B and A
im going with A

Answer 13

Did you do what I mentioned above. Solve for p using x = 15.
What do you get for p?

Here is choice A.
p = 4x + 50
p = 4(15) + 50
p = 60 + 50
p = 110
p = 110 means 110,000 people. We were told the population in 2025 is 450,000, so choice A. does not work.

Answer 14

Now let's try B.
p - 450 = 4(x - 15)
p - 450 = 4(15 - 15)
p - 450 = 0
p = 450
Here we do get p = 450, which means a population of 450,000 in the year 2025, so this choice looks good.

Answer 15

Choice D.
p = 4x + 15
p = 4(15) + 15
p = 60 + 15
p = 75
This means 75,000 people in 2025, so D is incorrect.
