Which property is illustrated in Step 2 ? Option B. Commutative property
How is this explained?
Given:
Step 1 = 10+ 8x - 10 - 4x +4 = 0
Step 2 = 10 + (-10+ 8x) -4x + 4
Here , 8x - 10 = -10 + 8x
This is of the form , A+B = B+A
Commutative property of addition = A+B = B+A
What is the commutative property?
The addition and multiplication arithmetic operations are covered by the commutative property. This implies that the outcome of adding or multiplying two numbers remains unchanged if the order or position of the numbers are changed. According to the commutative property formula, the result is unaffected by the sequence in which two numbers are added or multiplied. However, the order of the integers matters for subtracting and dividing any two real numbers, so it cannot be changed.Commutative property of addition = A+B = B+A Commutative property of multiplication = A B = B ATo learn more about commutative property, refer:

In angle VWX, VX is extended through point X to point Y,
m/VWX = (x + 14)°, m/XVW = (x +9)°, and
m/WXY = (5x - 10)°. What is the value of x?
Answers
Answer:
11
Step-by-step explanation:
This will form triangle VWX. So we have values for ∠VWX and ∠XVW but we don't have value for ∠WXV.
Since ∠WXV and ∠WXY are supplementary angles
=> ∠WXV + ∠WXY = 180
=> ∠WXV = 180 - ∠WXY
So the angles of triangle VXY
∠VWX + ∠XVW + ∠WXV = 180
(x + 14) + (x + 9) + (180 - (5x - 10)) = 180
x + x - 5x + 14 + 9 + 180 + 10 = 180
-3x + 213 = 180

What is the function operation ( f + g )(x) in the function?A function is simply a relationship that maps one input to one output.
Each x-values must have one y-value to qualify as a function.
Given the data in the question;
f( x ) = 4x + 1g( x ) = x² - 5( f + g )(x) = ?First, set up the function operation
( f + g )(x) = f(x) + g(x)
Replace the function designators f(x) and g(x) with the actual functions.
( f + g )(x) = f(x) + g(x)
( f + g )(x) = ( 4x + 1 ) + ( x² - 5 )
Collect and add like terms
( f + g )(x) = 4x + 1 + x² - 5
( f + g )(x) = 4x + x² - 5 + 1
( f + g )(x) = 4x + x² - 4

In 2003, the price of a certain automobile was approximately $30,600 with a depreciation of $1,440 per year. After how many years will the car's value be $19,080?
a) Write an equation to model the problem. Let t represent the number of years after 2003. For example, the year 2005 would be represented by t = 2.
Answer: ?
b) Solve the equation to find the answer to the question above. (Note: Include the units, in this case years.)
Answer: ?
Answers
1) An equation that models the problem is x = 30,600 - 1,440t, where x is the value after t years.
2) After 8 years of straight-line depreciation, the car's value will be $19,080.
What is depreciation?Depreciation is an accounting term that refers to the periodic expensing of the cost of a long-term asset.
Using depreciation, a reporting entity annually recognizes the cost of an asset used for many years.
Intangible long-term assets use amortization or depletion instead of depreciation to describe the same meaning.
Price of an automobile in 2003 = $30,600
Annual depreciation = $1,440
The car's value after t years = $19,080.
Equation Solution:Value after t years = 30,600 - 1,440t
If 19,080 = 30,600 - 1,440t
1,440t = 30,600 - 19,080
1,440t = 11,520
t = 8 (11,520/1,440)
t = 8
= 8 years
Check:
x = 30,600 - 1,440t
x = 30,600 - 1,440(8)
x = 30,600 - 11,520
x = 19,080

In triangle ABC, angle B is one-quarter of angle A and angle C is two fifth of angle A. If the size of angle A is (x- 10)°. Form an equation in x and hence calculate the angle of triangle ABC to the nearest degree.
Answers
When in triangle ABC, angle B is one quarter off angle B and angle C is two fifth of angle A and the angle A is (x-10) degrees, then the ∠A, ∠B and ∠C are 109 degrees, 27 degrees and 44 degrees respectively
The ∠A = (x-10) degrees
Angle B is one-quarter of angle A
∠B = (1/4)×(x-10)
= (1/4)x - (5/2)
= 0.25x-2.5
The angle C is two fifth of angle A
∠C = (2/5)(x-10)
= (2/5)x - 4
= 0.4x-4
We know sum of the angles in a triangle is 180 degrees
Then,
∠A + ∠B + ∠C = 180
Substitute the values in the equation
(x-10) + 0.25x-2.5 +0.4x-4 = 180
1.65x-16.5 = 180
1.65x = 196.5
x ≈ 119
∠A = (x-10)
= 119-10
= 109 degrees
∠B = 0.25x-2.5
= 0.25×119-2.5
≈ 27 degrees
∠C = 0.4x-4
= 0.4×119-4
≈ 44 degrees
Hence, when in triangle ABC, angle B is one quarter off angle B and angle C is two fifth of angle A and the angle A is (x-10) degrees, then the ∠A, ∠B and ∠C are 109 degrees, 27 degrees and 44 degrees respectively

find an equation of the form f(x)=ax^2+bx+c. must solve algebraically and check using a calculator (state, the steps used to perform the check).

Answers
By using algebra resolution methods for systems of linear equations, we find that the equation of the form f(x) = a · x² + b · x + c that passes through the three points is equal to f(x) = (5 / 2) · x² + (3 / 2) · x.
How to determine the quadratic equation that passes through three points
In this problem we must determine the coefficients of a quadratic equation that passes through the points (x₁, y₁) = (1, 4), (x₂, y₂) = (2, 13) and (x₃, y₃) = (4, 46). First, we need to create a system of linear equations by substituting on y and x thrice:
(x₁, y₁) = (1, 4)
a · 1² + b · 1 + c = 4
a + b + c = 4
(x₂, y₂) = (2, 13)
a · 2² + b · 2 + c = 13
4 · a + 2 · b + c = 13
(x₃, y₃) = (4, 46)
a · 4² + b · 4 + c = 46
16 · a + 4 · b + c = 46
Then, we find a system of three linear equations with three variables that offers an unique solution:
a + b + c = 4 (1)
4 · a + 2 · b + c = 13 (2)
16 · a + 4 · b + c = 46 (3)
There are different methods to find the solution to this system, we proceed to use algebraic substitution:
By (1):
c = 4 - a - b
(1) in (2) and (3):
4 · a + 2 · b + (4 - a - b) = 13
3 · a + b = 9 (2b)
16 · a + 4 · b + (4 - a - b) = 46
15 · a + 3 · b = 42 (3b)
By (2b):
b = 9 - 3 · a
(2b) in (3b):
15 · a + 3 · (9 - 3 · a) = 42
15 · a + 27 - 9 · a = 42
6 · a = 15
a = 15 / 6
a = 5 / 2
By (2b):
b = 9 - 3 · (5 / 2)
b = 9 - 15 / 2
b = 18 / 2 - 15 / 2
b = 3 / 2
By (1):
c = 4 - 5 / 2 - 3 / 2
c = 4 - 8 / 2
c = 4 - 4

[tex]\angle RTS\text{ + }\angle PTQ\text{ + }\angle QTR\text{ + }\angle PTS=360[/tex][tex]16\text{ + }16\text{ + }\angle PTS\text{ + }\angle PTS=360[/tex][tex]32\text{ + }2\angle PTS=360^{}[/tex][tex]\angle PTS=\frac{360^{}\text{ - 32}}{2}[/tex][tex]\angle PTS=\frac{328}{2}[/tex][tex]\angle PTS=164^{\circ}[/tex]Step 2: Let's determine the perimeter of the circle.
[tex]\text{ Perimeter = }2\pi r[/tex][tex]\text{ = 2}\pi(11)[/tex][tex]\text{ Perimeter = 22}\pi[/tex]Step 3: Let's determine the length of Arc PS.
[tex]\text{ Arc Length = (}\frac{\theta}{360})(\text{Perimeter of the Circle)}[/tex][tex]\text{ = (}\frac{164}{360})(22)(3.14)[/tex][tex]\text{ Arc Length = }31.469777\ldots\text{ }\approx\text{ 31.47 ft.}[/tex]Therefore, the length of Arc PS is 31.47 ft.

5.Given the functions f(x)=-2x + 4 and g(x) = 2x- 8, find the value of x for which f(x) = g(x).
6.Graph the function.
Answers
The value of x such that f(x) and g(x) have equal values is 3
What are linear equations?Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the value of x?From the question, we have
f(x) = -2x + 4
g(x) = 2x - 8
The question implies that the functions have equal values
This means that
f(x) = g(x)
Substitute f(x) = -2x + 4 and g(x) = 2x - 8 in f(x) = g(x)
So, we have the following equation
-2x + 4 = 2x - 8
Collect the like terms
2x + 2x = 8 + 4
Evaluate the like terms
4x = 12
Divide both sides of the equation by 4
x = 3
Hence, the value of x such that the equations are equal is 3

Rewrite the set T by listing its elements. Make sure to use the appropriate set notation.
T= {x|x is an integer and -5
Answers
The set T can be rewritten by listing its elements as T = {-4}.
What are sets?A set is a grouping of unique components that are denoted by curly brackets and commas.The term "elements of a set" refer to the collection of items in a set. A collection of fruits or a collection of images are two examples. Sets are additionally shown as follows.Set A = {a, b, c, d}. These are the elements of set A: a, b, c, and d.
Given:
Set T is equal to {x | x is an integer and -5 < x < -3}.
By examining the interval in the set, the set can also be written as something else.
It should be noted that the interval consists of two inequalities combined so that x > -5 and x < -3.
As -4 > -5 and -4 < -3 via the number line so it is the only element listed in the required set notation.
Hence, the set can be rewritten as
T = {-4}

[tex]a=22\\b=6\\c=14\\d=8[/tex]
Step-by-step explanation:
So (Didn't even know what it was until now), is a square where all rows, columns, and diagonals sum up to the same number.
So, from the diagonal of 7, 15, and 23, but adding them up, we can tell that each row, column, and diagonal should sum up to 45.
If we know that, you can solve it either arithmetically or algebraically (I'm going to sovle them algebraically)
Here are the equations I used to solve for each:
[tex]7+16+a=45\\23+a=45\\a=22\\\\24+15+b=45\\39+b=45\\b=6\\\\15+16+c=45\\31+c=45\\c=14\\\\14+23+d=45\\37+d=45\\d=8[/tex]
