Answer:

There are 8 bottles in each box.

Step-by-step explanation:

Victor has 12 boxes with 'n' number of water bottles in each box.

A dozen is same as 12.

Now, 12 boxes and each with 'n' number of bottles. Total number of bottles in '12' boxes is 12n bottles.

Now, it is removing 12(a dozen) bottles from 12n bottles which gives 84.

So, 12n -12=84

Add both sides 12

12n= 96

Divide both sides by 12

n=8

So, there are 8 bottles in each box.

Answer:

x = 3 and y = 0     or  (3, 0)

Step-by-step explanation:

First, you use the first equation to find what y equals.

3x + y = 9

y = 9 - 3x

Next, you plug in y to the second equation.

2x - y = 6

2x - (9 - 3x) = 6

2x - 9 + 3x = 6

5x - 9 = 6

5x = 15

x = 3

Then, you plug in x in the first equation.

3x + y = 9

3(3) + y = 9

9 + y = 9

y = 0

Taking into account the definition of a system of linear equations, the price of each bag of popcorn is $8 and the price of each pretzel is $4.25.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, the values ​​of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

On one hand, Julia went into a movie theater and bought 2 bags of popcorn and 5 pretzels, costing a total of $37.25.   This is expressed by 2x+5y= 37.25

Zoe went into the same movie theater and bough 8 bags of popcorn and 9 pretzels, costing a total of $102.25.  This is expressed by 8x+9y=102.25

So, the system of equations to solve is:

\(\left \{ {{2x+5y=37.25} \atop {8x+9y=102.25}} \right.\)

There are various methods to solve a system of equations, it is decided to solve by the substitution method, which consists of solving one of the two variables in one of the equations of the system and substituting its value in the other equation.

So, isolating the variable x from the first equation:

2x+5y= 37.25

2x= 37.25 - 5y

x= (37.25 - 5y)÷2

x= 18.625 - \(\frac{5}{2}\)y

Replacing in the second equation:

8×(18.625 - \(\frac{5}{2}\)y)+9y=102.25

Solving:

8×18.625 - 8×\(\frac{5}{2}\)y+9y=102.25

149 - 20y + 9y=102.25

149 -11y= 102.25

-11y= 102.25-149

-11y= -46.75

y= (-46.75)÷ (-11)

y= 4.25

Finally, replacing in x= 18.625 - \(\frac{5}{2}\)y and solving you get:

x= 18.625 - \(\frac{5}{2}\)×4.25

x= 18.625 - 10.625

x=8

Remembering that x represents the price of each bag of popcorn and y represents the price of each pretzel, you get that the price of each bag of popcorn is $8 and the price of each pretzel is $4.25.

Step-by-step explanation:

The steps in x are 1 -(-2) = 3, and the steps in y are -5 -(-11) = 6. The "rate of change" is the ratio of the change in y to the change in x:

  m = ∆y/∆x = 6/3 = 2

The rate of change represented by the values in the table is 2.

_____

Additional comment

The table can be described by ...

  y = 2x -7

A statement which best describes the function that represents the situation include the following: A) It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.

In Mathematics and Geometry, a linear function refers to a type of function whose equation is graphically represented by a straight line on the xy-plane or cartesian coordinate.

This ultimately implies that, a linear function has the same (constant) slope or ratio of change and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.

In this context, we have the following linear function;

F = 0.75x

where:

F represents the final cost in dollars.

x represents the price on the tag in dollars.

The area of mathematics known as probability deals with the outcomes of random events. Probability refers to a result's chance or potential. It clarifies the likelihood that a specific occurrence will take place. We frequently say things like, "He will probably pass the test," "There is very little chance of receiving a storm tonight," and "Most likely the price of onions will increase once more." We substitute the word probability for every instance of chance, uncertainty, likely, etc. in these statements.

In essence, probability is the ability to anticipate an outcome based on the variety and quantity of potential possibilities or the analysis of historical data.

Answer:

\(\boxed {\tt 11.6 \ feet}\)

Step-by-step explanation:

The area of a square can be found using the following formula.

\(A=s^2\)

We know the area of the patio is 135 square feet. Substitute 135 ft² in for A.

\(135 \ ft^2=s^2\)

We want to find the side length. We must isolate the variable, \(s\). on one side of the equation.

s is being squared. The inverse of a square is a square root. Take the square root of both sides of the equation.

\(\sqrt{135 \ ft^2} =\sqrt{s^2}\)

\(\sqrt{135 \ ft^2} =s\)

\(11.61895 \ ft =s\)

Round to the nearest tenth. The 1 in the hundredth place tells us to leave the 6 in the tenth place.

\(11.6 \ ft \approx s\)

Each side of the patio is about 11.6 feet.

The ordered pair lie on the inverse of the function is (62,−3).

Option A is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = -(x - 1)³ - 2

The inverse of f(x).

y = -(x - 1)³ - 2

interchange x and y and solve for y.

x = -(y - 1)3 - 2

(y - 1)³ = -2 - x

(y - 1)³ = -(2 + x)

Cuberoot on both sides.

y - 1 = ∛-(2 + x)

y = ∛-(2 + x) + 1

Now,

Substitute in the inverse of g(x).

(62, -3) = (x, y)

(−4, 123) = (x, y)

(3, 1) = (x, y)

(3,−6) = (x, y)

So,

y = ∛-(2 + x) + 1

y = ∛-(2 + 62) + 1

∛-1 = -1

y = -1∛64 + 1

y = -1 x 4 + 1

y = -4 + 1

y = -3

So,

(62, -3) ______(1)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 - 4) + 1

∛-1 = -1

y = ∛(-2 + 4) + 1

y = ∛2 + 1

y =  1.26 + 1

y = 2.26

So,

(-4, 2.26) _______(2)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 + 3) + 1

∛-1 = -1

y = -1∛5 + 1

y = -1 x 1.71 + 1

y = -1.71 + 1

y = -0.71

So,

(3, -0.71) _______(3)

And,

y = ∛-(2 + x) + 1

y = ∛-(2 + 3) + 1

∛-1 = -1

y = -1∛5 + 1

y = -1 x 1.71 + 1

y = -1.71 + 1

y = -0.71

So,

(3, -0.71) ______(4)

Thus,

From (1), (2), (3), (4) we see that,

(62, -3) is the solution to the inverse of g(x).

The expression 2x² + 7x + 6 can be factored as (2x + 3)(x + 2). To factor the expression 2x² + 7x + 6, we need to determine two binomial factors whose product is equal to the given expression.

We look for two numbers whose product is equal to the product of the coefficient of the x² term (2) and the constant term (6), which is 2 * 6 = 12. Additionally, we need to find two numbers whose sum is equal to the coefficient of the x term (7), which is 7.

The numbers that satisfy these conditions are 3 and 4, as 3 * 4 = 12 and 3 + 4 = 7. Therefore, we can write the factored form of the expression as (2x + 3)(x + 2).

Expanding this factored form using the distributive property, we get:

(2x + 3)(x + 2) = 2x² + 4x + 3x + 6 = 2x² + 7x + 6

Hence, (2x + 3)(x + 2) is the factored form of the expression 2x² + 7x + 6.

Given that the study was conducted using a sample of 513 bolts produced at a single facility when there is no bias resulting from data gathering procedures, broad inferences may then be drawn.

All bolts manufactured by that factory would be covered by the conclusion?

Due to the fact that bolts made in the same factory will follow the results of an analysis of a sample made up of bolts from the same factory. The finding or conclusion would therefore be applicable to all bolts produced in the same factory because the environment for experimentation and production is the same there while it may differ in other factories. Conclusions from the study may not apply to the bolts made by other companies as a result of this bias.
