Transformation is a term used in mathematics to refer to the movements made by objects.

information from the question

equation of the preimage f(x) = |x|

A graph showing the transformed image

The image show a reflection over x axis, the transformation rule for this is

Transformation rule (x, y) → (x, -y)

applying the rule to f(x) = |x| gives -f(x) = -|x|

followed by translation 2 units up, this achieved by Transformation rule

-f(x) → -f(x) + 2

Then a vertical stretch of 2 units,  transformation rule for vertical stretch is

Answer:

x=28

Step-by-step explanation:

angle b and angle c are the same measure because it is a iso triangle.

you know triangle sum is 180 so 3x+2(x+20)=180. simplify it to 5x=140

divide both sides by 5

x=28

Answer:

x = 28

Step-by-step explanation:

The triangle is isosceles, meaning that the two base angles (x + 20) are congruent. We can then create an equation that states: (x + 20) + (x + 20) + 3x = 180. Simplifying this, we get 5x + 40 = 180. We can then use reverse order of operations to solve it. Subtract 40 from both sides to get 5x = 140. We will then divide both sides by 5 to get x by itself, getting us the equation x = 28.

Answer:

x = -2.25

Step-by-step explanation:

To solve this we want to put the x alone on one side

Then by subtracting 6x from both sides

2x - 5 - 6x = 6x + 4 - 6x

- 4x - 5 =4

add 5 for both sides

- 4x - 5 + 5 = 4 + 5

- 4x = 9

Divide both sides by - 4

Then x = 9 / -4 = -2.25

So you only forget the negative sign

Glad to Help

Answer: x= - 9/4 or -2.25

Step-by-step explanation:

2x - 5 = 6x + 4(subtract 4 from the right side to move to the left side and subtract 2x from left side to move to right side)

-4 - 5 = 6x - 2x (now subtract these numbers as they have the same components)

-9 = 4x  (divide by 4 to get X alone)

-9/4 = x

In the given question we have to find the fraction of the wrestling matches did Rapunzel participate in.

Rapunzel's team participated in a total of 143 wrestling matches.

Rapunzel participated in 67 percent of the wrestling matches.

Total matches = 143

Participated in = 67%

Total number of matches in which Rapunzel participated is

The equation of the line is y = (-2/3)x + 8/3

What is a perpendicular line?

Two geometric objects are perpendicular in simple geometry if they intersect at a right angle. The perpendicular line can be used to graphically depict the condition of perpendicularity. It can be defined between any pair of lines, any pair of planes, or any pair of lines and planes.

The slope-intercept form of a line is written in the form:

y = mx + b

where:

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

Here, We have

y= 3/2x + 1/2 that passes through the point (-2,4)​

But we do not know the value of b.

We can do this by substituting the point(-2,4), into the equation and we get

y = mx + b

4 = (-2/3)(-2) + b

b = 8/3

Now that you know all your values, rewrite the equation in slope-intercept form:

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

Hence, the equation of the line is y = (-2/3)x + 8/3

William needs to detail his parents at least 12 times to buy the golf club.

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations.

The symbols we use in Inequality Expressions are

Not equal ' ≠ '  

Greater than  ' > '

Less than ' < '

Less than or equal  ' ≤ '

Greater than or equal ' ≥'

Here we have

William plans to buy the new Callaway Rogue for at least $ 550

The amount that William saved = $ 325

The amount he earns each time he details his parents = $ 20

Here we don't know how many times he detailed his parents,

So represent it with a variable x

After detailing x times the amount he earned will equal $ 20x

The total amount that William will have = $ 325 + $ 20x

William wants at least $550

Therefore,

The inequality that will represent the above situation is

=> 325 + 20x ≥ 550 ------(1)

Now solve the above inequality to get the value of x

=> 65 + 4x ≥ 110

=> 4x ≥ 45

=> x ≥ 11.25

Here we can say 11.25 times so x = 12 times

Therefore,

William needs to detail his parents at least 12 times to buy the golf club.

answer:

10

step-by-step explanation:

easy: 100 ÷ 10 = 10. you need 10

explanation: you need 100 (on the left side) to equal the right side. each weight on the right side weighs 10, but you don't know how many you need. use x for the unknown amount. now, you have:

100 = 10x. solve by dividing each side by 10.

10 = x. verify by doing 10 x 10 = 100

The equation 4y = -x is a direct variation and k = - 1 / 4.

The equation  3x = 2y - 7 is neither a direct variation nor a inverse variation.

Direct variation describes a simple relationship between two variables . We say y varies directly to x when it is represented as follows:

y = kx

where

Therefore,

4y =  - x

divide both sides of the equation by 4

4y / 4 = -x / 4

[tex]y =- \frac{x}{4}[/tex]

Therefore, the equation is direct variation and the value of k is - 1 / 4.

For two quantities with inverse variation, as one quantity increases, the other quantity decreases. Inverse variation is represented as follows:

y = k / x

Therefore, 3x = 2y - 7 is neither an inverse  nor a direct variation.

What is quadratic equation

it's a second-degree quadratic equation which is an algebraic equation in x. Ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the quadratic equation in its standard form. A non-zero term (a 0) for the coefficient of x2 is a prerequisite for an equation to be a quadratic equation. The x2 term is written first, then the x term, and finally the constant term is written when constructing a quadratic equation in standard form. In most cases, the numerical values of letters a, b, and c are expressed as integral values rather than fractions or decimals.

The equation given 3k² + k -3=0

(3k-1)(k+3)=0

k =1/3

k=0.33

Hence the value of k is 0.33.

For the given right angled triangle, the base of the triangle is 10 units and perpendicular side is 9 units then its side length x is equal to 13.45 units (nearest hundredth).

As given in the question,

Given right angled triangle,

Base of the triangle is equal to 10 units

Perpendicular side of a triangle is equal to 9 units

Side length 'x' is the hypotenuse of the right angled triangle.

Using Pythagoras theorem we get,

(Hypotenuse)² = ( Base)² + ( Perpendicular side)²

⇒ x² = (10)² + (9)²

⇒ x² = 100 + 81

⇒ x² = 181

⇒ x = √181

⇒ x = 13.4536...

⇒ x = 13.45 units ( nearest hundredth)  

Therefore, for the given right angled triangle, the base of the triangle is 10 units and perpendicular side is 9 units then its side length x is equal to 13.45 units (nearest hundredth).

An equation of the line in point-slope form that contains the point (-2, 5) and has a slope of 1/3 is y - 5 = 1/3(x + 2).

In Mathematics, the point-slope form can be defined as a type of equation that is typically used when the slope of a straight line and one of the points on this line is given (known).

Mathematically, the point-slope form of a straight line is given by this equation:

y - y₁ = m(x - x₁)

1. The Cost of Ending Inventory and the Cost of Goods Sold under LIFO, FIFO, and Weighted-Average, are as follows:

                                      LIFO           FIFO      Weighted-Average

Ending inventory          $425          $691                $573

Cost of goods sold      $492          $226               $344

FIFO (First-in, First-out) assumes that the physical flow of goods sold follows the chronological order of acquisition.

LIFO (Last-in, First-out) assumes that the cost of goods sold should be based on the latest inventory purchases.

The weighted-average method uses the average cost of goods to compute the ending inventory and the cost of goods sold.

LIFO:

Ending inventory = $425 ($917 - $492)

Cost of goods sold = $492 (12 x $20 + 12 x $21)

FIFO:

Ending inventory = $691 (9 x $11 + 17 x $20 + 12 x $21)

Cost of goods sold = $226 ($917 - $691)

Weighted Average:

Ending inventory = $573 (40 x $14.33)

Cost of goods sold = $344 (24 x $14.33)

                                   Units  Unit Cost    Total Cost
