Answer:

the input (x) values of the relation

Step-by-step explanation:

(a) No, The output (y) values of the relation are called Range. So it is the wrong option.

(b) Yes, the input (x) values of the relation are called Domain. Thus, it is the correct option.

(c) No, it is not a definition of Domain. Thus, this is an incorrect option.

(d) No, it is not a definition of Domain. It is called the cartesian point. Thus it is also an incorrect option.

Further,

The Domain is the all possible input values of a function that gives defined values.

The Range is the all defined output values that we get from a function (or y).

What ratio is equivilant to 4:13 which makes 85?

patriot [66]

Let us assume the common ratio to be = x
then
4x + 13x = 85
17x = 85
x = 85/17
= 5
Then
The ratio will be = 4 * 5:13 * 5
= 20:65
So the ration in which the number 85 can be separated is 20:65. i hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems without taking any help from outside. Only be careful while calculating.

19. The population of Jose's town in 1995 was 2400 and the population in 2000 was

Fantom [35]

The linear equation in slope intercept form for population of Jose's town is y = 320x + 2400.

<u>Solution:</u>

Given, the population of Jose's town in 1995 was 2400 and the population in 2000 was 4000,

Let x represent the number of years since 1995.

We have to write a linear equation, in slope- intercept form, that represents this data.

Now, let the change in population per year be p.

Then, population in a year = population change per year $\times$ number of years + population in 1995.

⇒population in a year = p $\times$ x + population in 1995

⇒ population in a year = p $\times$ x + 2400

Here we have an case that, population in 2000 is 4000

Then, number of years since 1995 = 5

So, 4000 = p $\times$ 5 + 2400 ⇒ 5p = 4000 – 2400 ⇒ 5p = 1600 ⇒ p = 320

Then, our equation will be population in a year = 320x + 2400

Considering the population in a year as y ⇒ y = 320x + 2400.

Hence, the linear equation in slope intercept form is y = 320x + 2400.
