Answer:

(6, 2)

Step-by-step explanation:

Midpoint between two points

[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\\\\\textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]

Defined points:

Substitute the defined points into the formula:

[tex]\textsf{Midpoint}=\left(\dfrac{4+8}{2},\dfrac{6-2}{2}\right)=(6,2)[/tex]

Therefore, the midpoint of the two given points is (6, 2).

The new function is g(x) =-1(1/-x) +2.

The transformation of function f(x) to function g(x) is given by g(x)=A f(Bx+ H)+K. where the constant A scales the function vertically. (A negative A reflects the function about the x-axis B scales the function horizontally. (A negative B reflects the function on the y-axis.) H shifts the function horizontally, and K shifts the function vertically.

Convert f(x) to g(x)

where the conversion is g(x)=f(x)+2.

A perpendicular line has negative reciprocal slopes, so for g(x) to be perpendicular to f(x), we need to get the negative reciprocal of -x, which is -1(1/-x)

So, f(x)=-x-2  ; m = -1

From the above information, we get g(x) as follows.

g(x) =-1(1/-x) +2

-42 is the constant for all values of x. If the given the functions f(x) = 3x - 21 and g(x) = 3x+21

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

Given an arbitrary number x, lets calculate,

⇒ f(x) - g(x)

                   =  3x - 21 - (3x+21)

                   = 3x - 3x -21 -21

                   = 0 - 42

                   = -42

and thus -42 is the constant for all values of x.

Step-by-step explanation:

Answer: Cynthia will receive $5,400, Moses will receive $8,100, John will receive $13,500

Step-by-step explanation:

       First, we will see how many "portions" the money is broken up into.

2:3:5 can become 2 + 3 + 5 = 10

       Next, we will see how much money each "portion" is worth using division.

$27,000 / 10 = 2,700

       Finally, we will multiply to see how much each person will receive.

2:3:5

2 * $2,700 = $5,400 [Cynthia]

3 * $2,700 = $8,100 [Moses]

5 * $2,700 = $13,500 [John]

Answer:

Cynthia's money = $5,400

Moses' money = $8,100

John's money = $13,500

Step-by-step explanation:

The full ratii of the money will be 2+3+5 = 10

Cynthia's ratio = 2 × $27,000

10

= 2 × 2,700

= $5400

Moses' ratio = 3 × $27,000

10

= 3 × 2,700

= $8100

John's ratio = 5 × $27,000

10

= 5 × 2,700

= $13,500

As time passes, the amount of money in the account increases.

The amount in the account increases by $45.

The amount of money in the account when he started depositing is  $197.

A linear function is a function that has one independent variable and one dependent variable. A linear function increases at a constant rate over a period of time. When drawn on a graph, a linear function is usually a straight line.

The form of linear functions is:

y = a + mx

Where:

Looking at the given table, it can be seen that as time passes, the amount of money increases.

Rate of increase = (change in the amount of money) / change in the months

(557 - 467) / (8 - 6)

= 90 / 2

= $45

Amount in the account at the beginning = account balance at 6 months - (rate of increase x 6)

467 - (6 x 45)

467 - 270 = $197

The range of the function g(x) = - 1 / 2 | x - 6 | + 1 is ( - ∞, 1].

We are given a function:

g(x) = - 1 / 2 | x - 6 | + 1

We need to find the range of the function.

Now, we can see that the tip of the function will be formed when | x - 6 | = 0

x - 6 = 0

x = 6

For x = 6, we have the value of g(x) as

g(x) = - 1 / 2 | 6 - 6 | + 1

g(x) = 0 + 1

g(x) = 1

Also, since - 1 / 2 is negative, the function will have range from negative infinity to 1.

So, the range of the function will become:

( - ∞, 1]

The solution of the given linear equation in one variable 0.2(x+3)-4(2 x-3)=0.9 is at x = 1.5.

According to the given question.

We have a linear equation in one variable.

0.2(x+3)-4(2 x-3)=0.9

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofore, the solution of the linear equation in one variable 0.2(x+3)-4(2 x-3)=0.9 is given by

0.2(x+3)-4(2 x-3)=0.9

⇒ 0.2x + 0.6 -8x + 12 = 0.9

⇒ -7.8x + 12.6 = 0.9

⇒ -7.8x  = 0.9 - 12.6

⇒ -7.8x = -11.7

⇒ x = -11.7/(-7.8)

⇒ x = 1.5

Using the general recursive formula, he 25-th term in the arithmetic sequence is 29.7

Here we have an arithmetic sequence with the first term a₁ = 3.3 and the common difference is d = 1.1

Remember that the general arithmetic recursive formula is:

aₙ = a₁ + (n - 1)*d

This formula allows us to find the n-th term of the arithmetic sequence only using the first term and the common difference.

In this case, we just need to replace n by 25 and the values written above.

a₂₅ = 3.3 + (25 - 1)*1.1 = 29.7

we have,

We have to find the value in kilowatt / hours power for per year basis

So, We know

Days in one year = 365

power in 3 days = 12 kilowatt/hours

For calculate power in single day, we have to divide power in 3 days by 3.

So power in a single day  = 12/3 kilowatt/hours

                                          = 4 kilowatt/hours

Now we have to multiply days in one year with power in a single day

     power for per year basis

                              = days in one year x power in a single day

Now, putting the all values,

                            = 365 x 4 kilowatt/hours.

The property tax be on a house that has a market value of $420,000 is A. $9,828

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Assessed value of a house = 60% of current market value

Property tax = 3.9% of the assessment value

Now the given market value of a house is $420,000

Assessed value of a house = 60% of $420,000

⇒ Assessed value of a house = 0.60 * $420,000

⇒ Assessed value of a house = $252,000

Thus, Property tax = 3.9% of $252,000

⇒ Property tax = 0.039 *$252,000

⇒ Property tax = $9,828

Thus, the property tax be on a house that has a market value of $420,000 is A. $9,828
