Answer:

The population of town B is 5 times greater than the population of town A

Step-by-step explanation:

Here in this question, we want to know the number of times in which the population of town B is greater than that of town A

To get the number of times, we simply divide the population of town B by the population of town A

From the question, the population of town B is 2 * 10^5 while the population of town A is 4 * 10^4

So to know the number of times,

We have (2 * 10^5) /(4 * 10^4) = 5

The population of town B is 5 times greater than the population of town A

Step-by-step explanation:

Clara wants to run 5 1/2 miles, and the track is only 0.25 miles long. This is a fairly easy question, you just need to figure out how many times 5 1/2 goes into 0.25, because she wants to run that amount of miles (I could never run that much).

I hope that answers your question so you understand, and I hope you have a great rest of your day! :)

[tex]x^{2}[/tex]Answer:

(Explanation)

Step-by-step explanation:

Part A:

The graph of y = [tex]x^{2}[/tex] + 2 will be translated 2 units up from the graph of y = [tex]x^{2}[/tex].

If you plug in 0 for x, you get a y-value of 2. The 2 is also not included with the [tex]x^{2}[/tex], which is why it doesn't translate left.

This is what graph A should look like:

Part B:

The graph of y = [tex]x^{2}[/tex] - 2 will be translated 2 units down from the graph of y = [tex]x^{2}[/tex].

If you plug in 0 for x, you get a y-value of -2. The 2 is also not included with the [tex]x^{2}[/tex], which is why it doesn't translate right.

This is what graph B should look like:

Part C:

The graph of y = 2[tex]x^{2}[/tex] is a stretched version of the graph y = [tex]x^{2}[/tex]. Numbers that are greater than 1 stretch and open up and numbers less than -1 stretch and open down.

This is what graph C should look like:

Part D:

The graph of y = [tex]\frac{1}{2}x^{2}[/tex] is a compressed version of the graph y = [tex]x^{2}[/tex]. Numbers that are in-between 0 and 1, and -1 and 0 are compressed.

Answer:So x=15 does not define a function. Another way of describing the condition above is that x=15 fails the vertical line test - the requirement that any vertical line intersects the graph in at most one point. This fails when x=15 because a vertical line at that point intersects the graph at infinitely many points.

Step-by-step explanation:

No x=15 is not a function.

What is Mathematical function ?

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.

In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.

Therefore, x=15 is not a function.

Answer:

2x - 5 = 47 is the expression .

x = 26

Step-by-step explanation:

The number is 26.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values. We frequently observe constant change in

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

given:

Five less than twice a number is equivalent to 47

let the number is x

So, 2x- 5= 47

Now solving for x

2x- 5= 47

2x= 52

x= 26

Hence, the number is 26

Answer:

(x, y, z ) = (4, 8, 12 )

Step-by-step explanation:

Given

x + y + z = 24 → (1)

5x + 3y + z = 56 → (2)

x + y - z = 0 → (3)

Eliminating z from the equations

Add (1) and (3) term by term

2x + 2y = 24 → (4)

Subtract (1) from (2) term by term

4x + 2y = 32 → (5)

Subtract (4) from (5) term by term

2x = 8 ( divide both sides by 2 )

x = 4

Substitute x = 4 into (4)

2(4) + 2y = 24

8 + 2y = 24 ( subtract 8 from both sides )

2y = 16 ( divide both sides by 2 )

y = 8

Substitute x = 4, y = 8 into (1)

4 + 8 + z = 24, that is

12 + z = 24 ( subtract 12 from both sides )

z = 12

Solution is x = 4, y = 8, z = 12

g(-2) = -7

Step-by-step explanation:

To find g(-2), plug -2 into g(x).

g(x) = -4x² + 3x + 15

g(-2) = -4(-2)² + 3(-2) + 15

g(-2) = -4(4) + 3(-2) + 15

g(-2) = -16 + (-6) + 15

g(-2) = -1 + (-6)

g(-2) = -7

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

If the lower level has 100 less than 2 times as many seats as the upper level then the expression is 2x-100 and the middle level has 80 more than 3 times as many seats as the upper level so it's 3x+80 and lastly the top level is just x.

so now for the equation you would add all those expressions and they all should equal 2680:

[tex]x+3x+80+2x-100=2680\\6x-20=2680\\6x=2700\\x=450[/tex]

but now don't forget to plug in for the middle level:

[tex]3x+80\\3(450)+80\\1350+80\\1430[/tex]

Therefore the middle level has 1430 seats.

Answer: 75 feet per hour

Step-by-step explanation:

X: 1, 3

Y: 200, 350

150/2

75

The rate of change in altitude is 75 feet per hour.

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

Given that,

Altitude of hiker after 1 hour = 200 feet

Altitude of hiker after 3 hours = 350 feet

The change in altitude = 350-200 = 150 feet

The difference of time = 3 - 1 = 2 hours

Rate of change = change in altitude/ change is time

                          = 150/2

                           = 75 feet per hour

The rate of change in altitude of the hiker is 75 feet per hour.
