The population of town has grown by 500 people each year over the last decade. Which equation could represent a linear model of the population?
f(x) = 500x + 12,000
f(x) = 500 - 12,000x
f(x) = 500 + 12,000x
f(x) = -500x + 12,000

f(x)= 500x + 12000
If the base population is 12000, which I’m sure it is then 500 would be added annually to that population per year which is why it says 500x. Therefore it would be the first one because it’s linear and it’s adding 500 per year.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
