       A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

         A domain's discreteness or continuousness can be determined by examining the function's graph. The domain is continuous if the graph is a line. The domain is discrete if the graph consists of a collection of points.

Private Domain

      The values that will be effective for the function are distinct from one another. The maximum number of children you can have, for instance, has a defined answer. You can have 0 children, 1, 2, 3, etc., but not 2,34.

      Discrete graphs are those in which no lines connect the points. Start by locating all the x-coordinates in order to determine the domain and range of a discrete graph. The graph's entire set of x-coordinates makes up the domain. The graph's entire range of y-coordinates is considered to be the range.

        The domain is the collection of all possible inputs for a function. The codomain is the collection of all permitted outputs.

     Graphs, logical assertions, and combinations are a few examples of discrete structures. Infinite or finite discrete structures are both possible. Contrary to continuous mathematics, which works with structures whose values can span the real numbers or have other non-separable qualities, discrete mathematics deals with discrete objects.

The cost of 6 bottles of juice is $2.34 if the each bottle costs the same.

According to the question,

We have the following information:

Adriel buys 20 bottles of grapefruit juice at the corner store for a total cost of $7.80.

Cost of 20 bottles of juice = $7.80

Now, from here we can find the cost of 1 bottle of juice by dividing the total cost by the number of bottles purchased.

Cost of 1 bottle of juice = $(7.80/20)

Cost of 1 bottle of juice = $0.39

Now, we can easily find the cost of 6 bottles of juice by multiplying the cost of 1 bottle of juice by 6.

Cost of 6 bottles of juice = $(0.39*6)

Cost of 6 bottles of juice = $2.24

Hence, the cost of 6 bottles of juice is $2.24.

Using proportions with mixed numbers, the inequality to determine the minimum number of hours she needs to practice on each of the 3 days is: m ≥ 3/4.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication or division.

One example is the mean of a data-set, as the mean is given by the sum of all observations in the data-set divided by the number of values.

For this problem, we have that:

Hence the minimum number of hours that she still needs to practice is:

5 - 2.75 = 2.25 hours.

The amount is split evenly amount the 3 days, hence the lower bound of the inequality is:

2.25/3 = 0.75 = 3/4.

Hence the amount is given by:

m ≥ 3/4.

The value of x is determined by solving the equation  14 + 5/7x - 20 = 4/7x - 4, which is: x = 14.

When given an equation, to solve the equation means to find the value of the variable in the equation.

Given the equation:

14 + 5/7x - 20 = 4/7x - 4

Combine like terms

5/7x - 6 = 4/7x - 4

Add 6 to both sides

5/7x - 6 + 6 = 4/7x - 4 + 6

5/7x = 4/7x + 2

Subtract both sides of the equation by 4/7x:

5/7x - 4/7x = 4/7x + 2 - 4/7x [subtraction property of equality]

x/7 = 2

Multiply both sides by 7

x/7(7) = 2(7) [multiplication property of equality]

Answer:

13/4 or 3.25

Step-by-step explanation:

Since they are vertical angles, they are equal to each other. Thus, set the two equations together:

8x + 32 = 12x + 19

Isolate x

32 = 12x + 19 - 8x = 4x + 19

32 - 19 = 4x

4x = 13

4x/4 = 13/4 = 3.25

There is no saddle point (DNE). However, there is local maximum at (1, 1/2) for the given function.

we have function of two variables f(x,y)= 9-2x+4y-x^2-4y^2

we will find the values by partial derivative with respect to x,y,xy

f ₓ= -2 -2x

[tex]f_{y}[/tex] = 4 -8y

to find the saddle point we should first find the critical points so equate

-2 -2x=0 and   4 -8y=0

we get x= 1  and y =1/2 so, critical points are (1,1/2)

to find local maximum or minimum we have to find  [tex]f_{xx}[/tex]  , [tex]f_{yy}[/tex] and [tex]f_{xy}[/tex]

formula is  [tex]f_{xx}[/tex]* [tex]f_{yy}[/tex] - [tex]f_{2xy}[/tex] =0

[tex]f_{xx}[/tex] = -2

[tex]f_{yy}[/tex] = -8

putting values in formula

(-2)*(-8) -0 =16 > 0, and [tex]f_{xx}[/tex] < 0  and [tex]f_{yy}[/tex] <0

If one student is chosen at random, the probability that the student was a female and got 'A' is 0.38

Probability is a synonym for potential. It is a field of mathematics that examines how random events happen. From zero to one, the value is expressed. To forecast the likelihood of events, probability has been introduced in mathematics.

The likelihood that something will occur is essentially what is meant by probability. This is the fundamental theory of probability, which is also used to calculate the probability distribution, and it is from it that you will learn the likelihood of various outcomes in a random experiment.

The total number of outcomes that can occur should be known before calculating the likelihood that a specific event will occur.

Total numbers of students = 53

Total numbers of females = 34

Total numbers of females of A grades = 20

So probability = 20/53

The fastest speed of the bird of species A is 136 mi/hr. and the fastest speed of the bird of species B is 34 mi/hr.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

A bird of species A, when diving, can travel four times as fast as a bird of species B at top speed which is given in the question.

Let b = the speed of bird species B.

So the speed of bird species A is 4b.

If the total speed for these birds is 170, then there is an equation :

⇒ 4b + b = 170.

⇒ 5b = 170

⇒ b = 170/5 = 34 mi/hr.

So the speed of bird species A will be 4×34 ⇒ 136 mi/hr.

Therefore, the fastest speed of the bird of species A is 136 mi/hr. and the fastest speed of the bird of species B is 34 mi/hr.

The conversion of 5 kiiometers to miles is 3.11 miles

The given parameters are

Distance covered by the students = 5 kilometers

The ratio of the distance is given as

1 mile : 1.61 kilometers

Multiply both sides of the ratio by 5

So, we have the following ratio expression

5 * 1 mile : 1.61 kilometers * 5

Evaluate the product in the above expression

So, we have the following ratio expression

5 miles : 8.05 kilometers

Divide both sides of the ratio by 1.61

So, we have the following ratio expression

5/1.61 miles : 8.05/1.61 kilometers

Evaluate the quotient in the above expression

So, we have the following ratio expression

3.11 miles : 5 kilometers

Rewrite as

5 kilometers : 3.11 miles

This means that

5 kilometers = 3.11 miles

Substitute 5 kilometers = 3.11 miles  in Distance covered by the students = 5 kilometers

The value obtained for f(3) after substituting x = 3 in the function f(x) is 0.0067.

A function from a set X to a set Y assigns exactly one element of Y to each element of X. The set X is known as the function's domain, and the set Y is known as the function's codomain.

The list of function formulas is divided into two categories: formulas for performing numerous arithmetic operations across functions and formulas for performing combined operations involving two or more functions.

The given function is f(x) = (1/7)/(7x)

We need to find the value of f(3) so we will substitute x = 3 in the given function as follows:

f(3) = (1/7)/(7×3)

∴ f(3) = (1/7)/21

∴ f(3) = 0.142/21

∴ f(3) = 0.0067

Therefore, after substituting x = 3 in the function f(x), the value obtained for f(3) is 0.0067.
