Answer:

1/24

Step-by-step explanation:

It's important to know that when there's an exclamation mark next to a number it means its multiplying itself by it's decreasing positive integers.

multiply

((3*2*1)(5*4*3*2*1))/((6*5*4*3*2*1)(4*3*2*1))

multiply again

((6)(120))/((720)(24))

and from here you simplify

720/17280

1/24

Answer:

B.

Step-by-step explanation:

We are given the function:

[tex]y=7870(1.01)^x[/tex]

Which represents the population of a certain city x years after it was founded.

The y-intercept is the y-value when x = 0. So:

[tex]y(0)=7870(1.01)^0=7870(1)=7870[/tex]

If x = 0, this means that zero years have passed since the city was founded.

So, the y-intercept represents the initial amount of people when the city was founded (in this case, there were 7870 people).

The correct answer is B.

Answer:

first equation : 3y + 6×=12

second equation : 4y + 8x = 16

Step-by-step explanation:

first equation

3y + 6× = 12

now take the common ,

3( y + 2x ) = 12

so, y + 2x = 4

second equation

4y + 8x = 16

4 ( y + 2x ) = 16

so, y + 2x = 4

two lines with same equation have infinitely many solution . these two equations are the same so there are infinitely many solution .

Answer:

c = 12.75n + 12

c = 15.75n

Step-by-step explanation:

Let

c = total​ cost of the ticket

n = number of people buying tickets

Buying tickets online

c = 12.75n + 12

Buying from the box office

c = 15.75n

This can be represented by the system of equation:

Answer:

y = 2x + 2

Step-by-step explanation:

The general form

is;

y = mx + b

where m is the slope and b is the y-intercept

so we have;

y = mx + 2

To get m, substitute the point (-1,0)

So we have

0 = -m + 2

m = 2

So the equation is;

y = 2x + 2

Answer:

22.75 applications

Step-by-step explanation:

From the above question, we understand that:

4 ​-oz bottle = 7 applications

13 ​-oz bottle = x applications

Cross Multiply

4 -oz bottle × x applications = 13 -oz bottle × 7 applications

x applications = 13 -oz bottle × 7 applications/4 -oz bottle

x applications = 22.75 applications

Therefore, the number of applications of the 13 -oz bottle​ self-tanner that should Jen​ expect is 22.75 applications.

The number of applications that Jen can expect from the self-tanner is 22.75 applications.

The first step is to determine how many applications 1 -oz of the bottle can provide.

Number of applications 1 -oz of the bottle can provide = 7/4 = 1.75

The second step is to multiply the figure gotten in the previous step by 13

13 x 1.75 = 22.75 applications
