The linear system with two variables is used to find the price. The price of each game is $60 and the price of each controller is $30.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

A customer at a video game store pays $420 for 6 games and 2 controllers.

A second customer pays $180 less than the first customer for 2 games and 4 controllers.

The price of each game is the same, and the price of each controller is the same.

Let x be the price of games and y be the price of the controller. Then the equations will be

6x + 2y = 420  ...1

2x +  4y = 240  ...2

By solving the equations 1 and 2, then we have

x = 60 and y = 30

Answer:y=2.5x

Step-by-step explanation:

We have been given a graph that shows numbers of servings (y) in different amounts (x) of frozen yogurt listed on a carton.

To write an equation that gives the number of servings y in x pints, we will have to find the slope (rate of change) of our given linear function.

Since we know that rate of change of a function can be found by vertical change of the function divided by horizontal change of the function.  

m= Slope (rate of change).

=Difference between two y-coordinates.

=Difference between corresponding x-coordinates of the y-coordinates.    

Upon substituting coordinates of two points (0,0) and (4,10) in slope formula we will get,  

The slope of our given line is 2.5.  

Now we will write equation of our given line is slope-intercept form. The equation of a line in slope-intercept form is: , where m=slope and b = y-intercept (initial value).

Upon substituting m=2.5 and coordinates of point (4,10) in slope-intercept form of equation we will get,

Upon substituting m=2.5 and b=0 in slope-intercept form of equation we will get,

Therefore, the equation  will give the number of servings y in x pints.

Answer:

Your answer is B) 3.6 cm.

Step-by-step explanation:

10 mm = 1 cm. To convert 36 mm to cm all you have to do is divide by 10.

36/10 = 3.6

So, 36 mm = 3.6 cm.

In the future, if you were to convert cm to mm, just multiply by 10.

Explanation:--

The Mean of the Data set is ---

2+5+1+7+6+4+3

7

= 4.

Hence, Mean of the data set is 4.

Answer:

To find the mean, you must add all the numbers and divide it by the amount of numbers in the set.

2 + 5 + 1 + 7 + 6 + 4 + 3
= 28
28 divided by 7 = 4

The answer is 4

Step-by-step explanation:

The arithmetic mean is the simple average, or sum of a series of numbers divided by the count of that series of numbers.

In the world of finance, the arithmetic mean is not usually an appropriate method for calculating an average, especially when a single outlier can skew the mean by a large amount.

Other averages used more commonly in finance include the geometric and harmonic mean.

Step-by-step explanation:

The total population of Deer's in the given span area is 5852 Deer's.

Population density is defined as the total number of humans presence

per unit square miles. Mathematically, we can write -

Population density = (Total human population)/(Total span area)

Given is that a county in north Carolina spans 532 square miles. the population density of deer in the county is 11 deer per square mile

We can write the total population of Deer's in the given span area as -

Population = Deer's population density x total area span

Population = 11 x 532

Population = 5852

Therefore, the total population of Deer's in the given span area is 5852 Deer's.

Step-by-step explanation:

3/4(x + 8) = 9 <== convert the fraction to a decimal

0.75(x + 8) = 9 <== distribute

0.75x + 6 = 9 <== subtract 6 from both sides

Charlene has a monthly salary of $3,410. with her present budget, the corrected net income is $113.70

Income tax is a tax applied on individuals or entities concerning income or profit earned by them.

Charlene has a monthly salary = $3,410.

Charlene has a net income that is 7% of her monthly salary.

The computation of the new net income is shown below

= Monthly salary × net income percentage - reduced amount of net income per month

= $3,410 × 7% - $125

= $113.70

Hence, the corrected net income is $113.70

Answer: W is now at (2,-3)

Step-by-step explanation: flip by the x-axis to turn (-2,3) to (-2,-3) then flip it on the y-axis to turn (-2,-3) to (2,-3).

The time taken to have a total of $21,000 is 36.5 years.

To calculate the time it takes to reach $21,000 with a simple annual interest rate, we can use the formula for simple interest:

Interest = Principal × Rate × Time

Where:

Interest is the additional amount earned on the initial investment (in this case, the difference between $21,000 and $8,600),

Principal is the initial investment ($8,600),

Rate is the annual interest rate (3.95% expressed as 0.0395),

and Time is the unknown variable we want to find.

We can rearrange the formula to solve for Time:

Time = Interest / (Principal × Rate)

Let's plug in the values:

Interest = $21,000 - $8,600 = $12,400

Principal = $8,600

Rate = 0.0395

Time = $12,400 / ($8,600 × 0.0395) ≈ 36.5

So, it will take approximately 36.5 years to have a total of $21,000.
