Furthermore, we can use mathematical induction to prove statements about any well-ordered set, not just the natural numbers

Mathematical induction is a valid proof technique because it allows us to prove a statement for an infinite number of cases by proving it for just two cases: a base case and an induction step.

Suppose: We suppose the statement is true for some particular case, usually the base case.

To show: We then show that the statement is also true for the next case, usually the induction step.

Then the: We can then conclude that the statement is true for all cases.

We know that: We know that the base case is true because we have verified it directly. We also know that the induction step is true because we have assumed that the statement is true for some particular case and then shown that it must also be true for the next case.

Furthermore: Furthermore, we can use mathematical induction to prove statements about any well-ordered set, not just the natural numbers.

Answer:

  x = -7y/(4 +5y)

Step-by-step explanation:

You can treat y as though it were a constant. As in any 2-step linear equation, you separate the variable term(s) from the constant term, then divide by the coefficient of the variable.

  4x +5xy = -7y . . . . . subtract 7y

  x(4 +5y) = -7y . . . . . factor out x, so we can see its coefficient

  x = -7y/(4 +5y) . . . . divide by the coefficient of x

For the given relation for (x , y) ∈R if x ≥ y defined on the set of positive integers only transitive relation holds true.

As given in the question,

Given (x , y) ∈R

To check whether relation reflexive, symmetric, antisymmetric, transitive, and/or a partial order is true or not:

a. Reflexive : If (x, x)∈R for all x ∈R

x ≥ x for all x ∈ R which is not true.

b. Symmetric : If 'x' is related to 'y' then 'y' is also related to 'x' for all      (x, y) ∈R.

Here, x ≥ y ⇒ y ≥ x for all (x, y) ∈R , which is not true.

c. Antisymmetric : If 'x' is related to 'y' and 'y' is related to 'x' then x = y for all (x , y)∈ R.

Here, x ≥ y and y ≥ x ⇒ x = y is not true.

Not antisymmetric.

d. Transitive: If 'x' is related to 'y' and 'y' is related to 'z' then 'x' is related to 'z' for all x, y, z ∈R.

Here,  x ≥ y , y ≥ z ⇒ x ≥ z for all x, y, z ∈R.

The way fuel consumption of a car change as its speed increases represents a relationship that is curved with higher at extremes when scatter plot is constructed. It shows fuel efficiency is high at moderate speeds.

What is scatter plot?

A scatter plot is a type of mathematical diagram using Cartesian coordinates to demonstrate values for typically two variables for a set of data.

Main body:

In the given case, the scatter plot shows a relationship between the speeds of a car and fuel consumption.

The curved relationship which is high on extreme and low in the middle. As the car speed increases from 10km/h to 60 km/h, the fuel consumption decreases. As the car speed increases from 60km/h to 150khm/h, the fuel consumption increases. Hence, the fuel consumption is lowest at 60km/h and its generally low for moderate speeds – 40 km/hr to 100 km/h. It can be deduced that fuel efficiency (which pertains to how well a vehicle uses fuel) is high for moderate speeds.

Hence, at moderate speeds best performance is achieved.

Answer:

-4.2c+4.8d

Step-by-step explanation:

(−7c+8d)0.6

Distribute

-7c*.6 + 8d * .6

-4.2c+4.8d

Answer:

-4.2c + 4.8d

Step-by-step explanation:

We would like to distribute the 0.6 in the expression (-7c + 8d) * 0.6.

Remember that when distributing, we multiply the "outside number" (0.6 in this case) by each of the "inside numbers" (-7c and 8d) and then add those products.

So, the first product will be: 0.6 * (-7c) = -4.2c. The second product will be: 0.6 * 8d = 4.8d. Add these together: -4.2c + 4.8d.

The answer is thus -4.2c + 4.8d.

a) Diminishing returns start at x = 1,  where the marginal revenue will be less than the marginal cost

b)At x = 1, the company will earn R(1) = -32 + 6 + 18 + 4 = -4,000 dollars.

c) 0 ≤ x ≤ 25 implies that the Coffee Junction company has the capacity to spend a maximum of 25,000 dollars per month on advertisements.

a) At what level of advertising spending does diminishing returns start?

Diminishing returns refers to a situation when the marginal return on investment decreases as more resources are devoted to it. For instance, in case of Coffee Junction, increasing the advertising expenditure may lead to higher revenue, but the marginal revenue (revenue generated by each additional dollar spent) will gradually decrease.

b) How much revenue will the company earn at that level of advertising spending?

At x = 1, the company will earn R(1) = -32 + 6 + 18 + 4 = -4,000 dollars.

c) What does 0≤x≤25 tell us with respect to this problem?

In this problem, 0 ≤ x ≤ 25 implies that the Coffee Junction company has the capacity to spend a maximum of 25,000 dollars per month on advertisements.

This equation is not true, and there is no value of x that can make it true. Therefore, none of the provided answer options (OA 5, B. -2, oc. – 1/2, colw win) is correct.

To solve the equation -121 – 2(3 + 9) = 5(1 + 4), we need to simplify both sides and find the value of x that makes the equation true.

Starting with the left side of the equation:

-121 – 2(3 + 9) = -121 – 2(12) = -121 - 24 = -145

Now, let's simplify the right side of the equation:

5(1 + 4) = 5(5) = 25

So the equation becomes:

-145 = 25

Let x be the no.of square feet for landscaping

Company A

Monthly consulting fee = $250

Cost of landscaping of 1 sq.feet = $10

Cost of landscaping of x sq.feet = $10x

So, Total charge by company A = 250+10x  ---1

Company B

Monthly consulting fee = $90

Cost of landscaping of 1 sq.feet = $12

Cost of landscaping of x sq.feet = $12x

So, Total charge by company B = 90+12x   ---2

Now we are supposed to find  how many square feet of landscaping will the two companies charge the same amount

So, Equate 1 and 2

\(250+10x=90+12x\\160=2x\\80=x\)

So, the two companies charge the same amount for 80 sq.feet

Total charge by company A for 80 sq.feet = 250+10(80)= $1050

Total charge by company B for 80 sq.feet = 90+12(90)=$1170

Step-by-step explanation:

on the first step, where the student subtracted the two equations, when they subtracted 3y - y, they got 4y, but they were supposed to get 2y.

If they did it right it would look like this

 2x + 3y = 8

-(2x  +  y = 16)

0x + 2y = -8

y = -4

2x - 4 = 16

2x = 20

x = 10

Solution (10,-4)

You must find the error, I will correct their work.

This is a system of linear equations. To solve it, you can use the substitution method. First, you can solve the first equation for x and substitute it into the second equation:

2x + 3y = 8

2x = 8 - 3y

x = (8 - 3y) / 2

2((8 - 3y) / 2) + y = 16

8 - 3y + 2y = 16

5y = 8

y = 8 / 5

Then, you can substitute y into the first equation:

2x + 3(8 / 5) = 8

2x = 8 - 24 / 5

2x = 16 / 5

x = 16 / 10

Therefore, the solution to the system of linear equations is x = 16/10 and y = 8/5.

Here is a sample correction to this (paraphrase):

When you tried to solve the system of linear equations, you likely made a mistake when solving one of the equations for a variable or when substituting the values into the equations. To ensure that you get the correct solution, you should double-check your work and make sure that the values you get satisfy the original equations.

For accounting purposes, depreciation is an allocation of a cost of an asset.

Both depreciation and amortization are techniques for spreading out an asset's cost throughout its useful life, although they are employed for various asset categories. Whereas amortisation is used for intangible assets like patents, copyrights, and trademarks, depreciation is utilised for tangible assets like buildings, machinery, and equipment. Depreciation is a method used to account for an asset's decline in value as a result of damage or obsolescence. During the course of the asset's useful life, the asset's cost is distributed to match the income it produces.

Answer:

s = 20

Step-by-step explanation:

Given

3 = - 2 | 0.25s - 5 | + 3 ( subtract 3 from both sides )

0 = - 2 | 0.25s - 5 | ( divide both sides by - 2 )

0 = | 0.25s - 5 | , then

0.25s - 5 = 0 ( add 5 to both sides )

0.25s = 5 ( divide both sides by 0.25 )

s = 20

Answer: S=20

Step-by-step explanation:

Data: 3=-2(0.25s-5)+3

S=?

Step one, Multiply .25s and -5 by -2

-2x0.25s=-0.50s

-2x-5=10

Reason: When something is in parenthesis, that is the first thing you evaluate, and since -2 is right next to the parenthesis, you multiply both numbers by -2 to get -.50s and 10

Step two, add like terms

3=-.50s+10+3=3=-.50s+13

Reason: When there are like terms(terms with the same variable or same exponent, etc.) You have to add them or else evaluating things will get harder to do as you go on, in this case, the two like terms(3 and 10) added together get 13.

Step three, subtract 13 on both sides

3-13=-.50s+13-13

-10=-.50s

Reason: Because the point of this is to single out 's', you have to get rid of the 13 and since it's a positive 13, you add it to a negative to cancel it out, but what you do to one side you do to the other so you subtract 13 from 3 to get negative 10.

Step four, divide -.50 on both sides

-10/-.50=-.50s/-.50

S=20

Reason: Since you have to isolate 's' and it's right next to -.50(which means multiplication), you have to divide it to get rid of it. Since what you do to one side you do to the other, you divide -10 by -.50 to get 20=S
