We need to write interval for the number from -5 to 2.

We need to exclude numbers -2 and 2 from it.

First we need to note some important points about interval notation.

We need to check, which numbers are included and which numbers are excluded in the given interval.

We use open-interval ( or ) for excluded values and [ or ] close-interval for included values.

For the given problem, we have given three numbers: -5, -2 and 2.

It's clarly given that -2 and 2 are not included. But it is not said that -5 is excluded, so -5 is included number.

-2 comes in between -5 and 2 on the number line.

So let us write interval notation from -5 to -2. (Note : -5 is included and -2 excluded).

Therefore, we will write close interval " [ " on left side of -5 and an open interval " ( "on right side of -2. We get,

[-5 , -2 ).

Now, we will write interval notation from -2 to 2.

Both are excluced values, os we will take open intervals ( ) on left and right side of -2 and 2.

So, we get another part of the interval as

(-2,2).

We will put union symbol in between above two interval notations we get.

Therefore, final interval notation is

[-5 , -2 ) ∪ (-2,2).

The population of Farmersville can be modeled by the inequality y > 2,000x + 2,100, where x is the number of years since 2010
Kaylis [27]

Answer:

The population can be greater than 6,100 but less than 6,300, and thus, we cannot determine if the population of Farmersville will be greater than 6,300 in 2012.

Step-by-step explanation:

Inequality for the population of Farmsville:

The inequality for the population of Farmsville in x years after 2010 is given by:

y(x) > 2000x + 2100

Will the population of Farmersville be greater than 6,300 in 2012?

2012 is 2012-2010 = 2 years after 2010, so we have to find y(2).

y(2) > 2000(2) + 2100

y(2) > 6100

The population can be greater than 6,100 but less than 6,300, and thus, we cannot determine if the population of Farmersville will be greater than 6,300 in 2012.
