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.

Step-by-step explanation:

9/12 if we divided by 3

6/8 if we divided by 2

The two fractions when multiplied together make 3/4 are, 1/2 and 3/2.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

The first fraction can be 1/2 when multiplied by the second fraction 3/2.

Therefore,

The two fractions, when multiplied together make 3/4 is (1/2)×(3/2).

Answer:

The correct answer is x= 4/5 because you cannot take the root of a negative number

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

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

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:

c = 12.75n + 12

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 .
