Does anyone remember how to do domain and range?

Answers

Answer 1

Answer:

Ummm no not really

Step-by-step explanation:

Answer 2

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Human population numbers are in constant flux. Suppose a country has a population of 20 million people at the start of one year and during the year there are 600,000 births, 350,000 deaths, 100,000 immigrants, and 5,000 emigrants. You and your classmates will determine the total population at the end of the year and then model expected change over a longer period.

Answers

According to the question given,

[tex]\sf\longmapsto \: emigrants=-5000[/tex]

[tex]\sf\longmapsto \: Immigrants = 100000[/tex]

[tex]\sf\longmapsto \: Death -350000[/tex]

[tex] \sf \longmapsto \: Birth=600000[/tex]

Now let's solve out and get the result!

The change of population:

[tex] \sf \longmapsto600000-350000 + 100000 - 5000=350000[/tex]

The total population at the end of the year:

[tex]\sf\longmapsto \:2000000 + 350000 [/tex]

[tex]\sf\dashrightarrow2350000[/tex]

Hence the total population at the end of the year is 2350000.

At the end of the year, the population will be 20,345,000.

The rate of change in population is 1.75%.

What is rate?

Rate is a measurement to determine the change in one quantity with respect to another quantity.

The given information are,

Total population of the country initially = 20,000,000

Total number of births during the year = 600,000

Total number of deaths during the year = 350,000

Number of immigrants = 100,000

And number of emigrants = 5,000

The population at the end of the year

= 20,000,000 + 600,000 - 350,000 + 100,000 - 5,000

= 20,345,000

At the end of the year the population will be 20,345,000.

The increase in population = 20,345,000 - 20,000,000

= 345,000

the rate of increasing = 345000/20000000)x100 = 1.75%

The rate of change per year is 1.75%.

Solve each system by elimination.

3) 3x + 4y = 12
-3x - y = 6

4) -5x – 6y = 5
-6x + 6y = 6

5) 7x - 4y = 19
10x - 2y = 16

6) 10x - 9y=-13
5x – 3y =-11

Answers

Answer:

3) x = -4 and y = 6

4) x = -1 and y = 0

5) x = 1 and y = -3

6) x = -4 and y = -3

Step-by-step explanation:

3) Add the equations:

(3x + 4y = 12) + (-3x - y = 6) (eliminate the x)

= 3y = 18

y = 18/3

y = 6

3x + 4(6) = 12

3x = 12 - 24

x = -12/3 = 4

4) Add the equations:

(-5x - 6y = 5) + (-6x + 6y = 6)

-11x = 11

x = -1

-5(-1) -6y = 5

-6y = 5 - 5

y = 0

5) 7x -4y = 19

10x - 2y = 16

Multiply the second equation by -2 to eliminate the y and add both equations.

-2(10x -2y = 16) =

(-20x + 4y = -32) + (7x - 4y = 19)

-13x = -13

x = 1

7(1) - 4y = 19

-4y = 19-7

y = 12/-4

y = 3

6) multiply the second equation by -2 to eliminate the x and then add the equations.

-2(5x - 3y = - 11) =

(-10x + 6y = 22) + (10x - 9y = - 13)

= -3y = 9

y = - 3

10x - 9(-3) = - 13

10x = -13 - 27

x = -40/10

x = -4

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The high temperature was recorded as 23 7°F = +23.7

the low temperature that same day was recorded as 6.9°F = -6.9 F

so, difference between the high and low temperatures for that day

= 23.7- (-6.9)

= 30.6
