Step-by-step explanation:

7(4n−6)=6+4(4+3n)

Step 1: Simplify both sides of the equation.

7(4n−6)=6+4(4+3n)

(7)(4n)+(7)(−6)=6+(4)(4)+(4)(3n) (Distribute)

28n+−42=6+16+12n

28n−42=(12n)+(6+16) (Combine Like Terms)

28n−42=12n+22

Step 2: Subtract 12n from both sides.

28n−42−12n=12n+22−12n

16n−42=22

Step 3: Add 42 to both sides.

16n−42+42=22+42

16n=64

Step 4: Divide both sides by 16.

[tex]\frac{16n}{16} = \frac{64}{16}[/tex]

The combination of a rotation and a translation transformation can map triangle mnq onto triangle pqn.

It is possible to map triangle mnq onto triangle pqn by performing a combination of rotation and translation transformations.

First, triangle mnq can be rotated about point n by a certain angle to form a new triangle that is congruent to triangle mnq. This rotation transformation preserves the size and shape of the triangle but changes its orientation.

Next, the rotated triangle can be shifted to the left to form triangle pqn. This translation transformation moves the triangle to a new position without changing its size or shape.

Therefore, the combination of a rotation and a translation transformation can map triangle mnq onto triangle pqn.

Answer:

b = 2sqrt(5)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

4^2 + b^2 = 6^2

16+b^2 = 36

b^2 = 36-16

b^2 = 20

Taking the square root of each side

sqrt(b^2) = sqrt(20)

b = sqrt(20)

b = sqrt(4*5)

b = sqrt(4) sqrt(5)

b = 2sqrt(5)

b = 2sqrt(5)

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

4^2 + b^2 = 6^2

16+b^2 = 36

b^2 = 36-16

b^2 = 20

Taking the square root of each side

sqrt(b^2) = sqrt(20)

b = sqrt(20)

b = sqrt(4*5)

b = sqrt(4) sqrt(5)

b = 2sqrt(5)

Answer: 48°

Step-by-step explanation:

       We know that the angles of a triangle are equal to 180 degrees when added together. Using this logic, we will create an equation to solve for x. Then we will substitute this value of x back into the expression for angle F.

   Given:

E + D + F = 180°

   Substitue:

(8x - 18)° + (6x - 4)° + (5x - 7)° = 180°

   Reorder and combine like terms:

8x° + 6x° + 5x° - 18° - 4° - 7° = 180°

19x° - 29° = 180°

   Add 29 to both sides of the equation:

19x° = 209°

   Divide both sides of the equation by 19:

x = 11

   Substitute this value of x into the expression for angle F:

(5x - 7)°

(5(11) - 7)°

(55 - 7)°

Given:

Analysis is a regression analysis.

And the error term in regression analysis:

The error term, which refers to the total of the deviations within the regression line and explains the discrepancy between the theoretical value of the model and the actual observed results, denotes the margin of error inside a statistical model.

ε = Epsilon or error term.

The variation in the dependent variable that the independent factors do not explain is taken into account by the error term.

The values of the error term should be determined by random chance.

The average value of the error term must be equal to zero in order for your model to be impartial.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given  two numbers,

let the numbers be a and b,

and the product of a and b is -70.

a x b = -70

addition of numbers is 9

a + b = 9

substitute value of a

-70/b + b = 9

b² - 9b - 70 = 0

Implementing a new system into an organization module by module is called a​ phased approach.

A phased approach is one of two common methods used to develop an ERP system solution. In this strategy, the system's functionalities are introduced in a certain order, gradually replacing previous systems and processes.

This frequently indicates that a business starts off with core functionality that is given top attention, and then other applications are gradually added in stages over time. An alternative implementation strategy, however, uses an all-at-once model in which the system and all apps "Go Live" simultaneously.

The optimal implementation plan for your firm will depend on the needs, goals, and strategies you have for it. This might involve a hybrid strategy where crucial functionality is added to the core ERP programs first, and then desirable features are added later on in a staged implementation. By considering all of your options, your firm can decide which will serve its interests the most effectively.

The larger side of the rectangle is 70 cm and the area is 3150 cm²

A 4-sided flat shape with straight sides where all interior angles are right angles (90°). Also, opposite sides are parallel and of equal length.

Given that, the sides of a rectangle are in the proportion 9:14 and the perimeter of the rectangle is 230 cm

Let the smaller side of the rectangle be 9x and larger side be 14x

We know that the perimeter of a rectangle = 2(l+w)

Therefore, perimeter = 2(9x+14x)

2(9x+14x) = 230

2×23x = 230

2x = 10

x = 5

Therefore, the smaller side of the rectangle is 45 cm and larger side is 70 cm

Step-by-step explanation:

Here are a few tips for quickly dividing large numbers and decimals:

Use estimation: Estimate the quotient by rounding the dividend and divisor to easy numbers. This can save time and give you a rough idea of the answer.

Use long division: This method can be used to divide larger numbers, and it involves breaking down the dividend into smaller parts, dividing each part by the divisor, and then combining the results.

Use a calculator: A calculator can quickly divide large numbers and decimals, and it eliminates the need for long division or estimation.

Use the reciprocal: Dividing by a number is the same as multiplying by its reciprocal, so if you know the reciprocal of the divisor, you can use it to quickly divide any number.

Use mental math: If you are comfortable with mental math and good at it, you can use it to quickly divide numbers. This can help you to quickly divide large numbers and decimals.

Use the method of repeated subtraction or shifting the decimal point: Instead of dividing by repeatedly subtracting the divisor from the dividend or shifting the decimal point, this method can also be used to divide large numbers and decimals.
