__

The system can be solve by substituting for x:

  (2y) +y = 36

Tell how the Communicative property of addition and the Associative property of addition can help solve the problem mentally 8+(
topjm [15]

Step-by-step explanation:

Communicative property states that, in addition, integers added in any order will still give the same answer.

So in this question,

rather than first adding 8 + (-5), we add 8 + (-8)

We know that a number + its additive Inverse (opposite sign) is equal to zero

And we know any number added to zero is equal to the number.

So we can quickly find out that the sum is -5

1 pts The function f(x) = 12,900(0.40)x models the population of ants in a house x days after their discovery. Which statement d
Amiraneli [1.4K]

Answer:

f(x) = 500 • 1.1x

Step-by-step explanation:

To solve the question, we need to understand that:

- The population of ants is going to increase with time as they mate and have a population positive growth rate.

- The initial number of ants is 500.

- The rate at which it increases will be multiplied with x months

We will work our way out by removing the wrong answers first

Since,

The population cannot be decreased so we can neglect the last two options involving 0.9 as it will result in a decrease in the population.

Now we are left with two options:

a)  f(x) = 500 • 1.1x

b) f(x) = 1.1 • 500x

Since in the option (b) , 500 is multiplied with x , it is not possible as 500 is a constant initial amount and not a factor of growth of population. The growth factor is supposed to be multiple of x months.

So, the correct answer is f(x) = 500 • 1.1x
