Quadrilaterals WXYZ and W"X"Y"Z"are similar. Identify the type of reflection

performed and the scale factor.

A)

To obtain quadrilateral W"X"Y"Z" quadrilateral WXYZ is reflected across

the x-axis and dilated with a scale factor of 3.

B) To obtain quadrilateral W'X'Y"Z" quadrilateral WXYZ is reflected across

the x-axis and dilated with a scale factor of 1/2

c) To obtain quadrilateral W'X'Y"Z" quadrilateral WXYZ is reflected across

the x-axis and dilated with a scale factor of 2.

D) To obtain quadrilateral W X Y Z" quadrilateral WXYZ is reflected across

the x-axis and dilated with a scale factor of 1/3.

Answers

Answer:

B) To obtain quadrilateral W'X'Y"Z" quadrilateral WXYZ is reflected across

the x-axis and dilated with a scale factor of 1/2

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

If a point A(x, y) is reflected across the x axis the new point is at A'(x, -y)

Dilation is the enlargement or reduction in the size of a figure by a scale factor. If a point A(x, y) is dilated by a scale factor of k about the center of origin, the new point is at A'(kx, ky).

The vertex of Quadrilaterals WXYZ is at W(-6, 8), X(-2, 8), Y(-2, 2), Z(-6, 8) while the vertex of Quadrilaterals W"X"Y"Z" is at W"(-3, -4), X"(-2, -4), Y"(-1, -1), Z"(-3, -4)

If quadrilateral WXYZ is reflected across  the x-axis, the new coordinates would be at W'(-6, -), X'(-2, -8), Y'(-2, -2), Z'(-6, -8). If the quadrilateral is then dilated with a scale factor of 1/2, the new point is at W"(-3, -4), X"(-2, -4), Y"(-1, -1), Z"(-3, -4)

The Sports Committee wants to use its share of the money to purchase t-shirts. If each t-shirt costs $12, what is the greatest number of t-shirts the Sports Committee can purchase? The greatest number of t-shirts that the Sports Committee can purchase is .

Answers

Answer:

The greatest number of t-shirts that the Sports Committee can purchase is 232.

Step-by-step explanation:

The student council raised $2,790 during its annual fundraiser.

Each t-shirt costs $12.

The total cost of buying x t-shirts is given by:

[tex]T(x) = 12x[/tex]

What is the greatest number of t-shirts the Sports Committee can purchase?

The total cost has to be lesser, or equal, to 2790. So

[tex]T(x) \leq 2790[/tex]

[tex]12x \leq 2790[/tex]

[tex]x \leq \frac{2790}{12}[/tex]

[tex]x \leq 232.5[/tex]

Since you cant buy half a shirt.

The greatest number of t-shirts that the Sports Committee can purchase is 232.

Select the expression equivalent to -81 x + 27.
A -9(9 x - 3)
B -9(-9 x - 3)
C 3+ (-27 x +9)
D -3(-27 x +9)

Answers

Answer:

B -9(9x-3)

Step-by-step explanation:

b/c -9(9x-3) means -9×9x-(-3)

= -81x+27

if you say why -(-3) is +27, I will say b/c negative times negetive it give us positive. and if you they why we don't add -81x and 27, I will say b/c they are not like terms.

like terms : are terms with the same variable and same exponent.

Which of the following equations correctly describes the graphed line?




y = -1/2x - 5


y = -1/2x + 5


y = 1/2x + 5


y = 1/2x - 5

Answers

Answer:

Option C i.e. y = 1/2x + 5 is the correct option.

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

m is the slope b is the y-intercept

Given the points

A(4, 7)

B(-4, 3)

Determining the slope between A and B

(x₁, y₁) = (4, 7) (x₂, y₂) = (-4, 3)  

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]  

                 =  [3 - 7] / [-4 - 4]    

                 = -4 / -8

                 = 4/8

                 = 1/2

Thus, the slope of the line = m = 1/2

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 5

Thus, the y-intercept b = 5

now substituting m = 1/2 and b = 5 in the slope-intercept form

y = mx+b

y = 1/2x + 5

Therefore, the equation of line in the graph is:

y = 1/2x + 5

Thus, option C i.e. y = 1/2x + 5 is the correct option.

State whether the following mapping represents a function. Then give the domain and range.

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

Let us create the table from the given mapping

x                  y

2                20

2                40

4                40

3                30

From the table, it is clear that the input x = 2 is repeated twice. In other words, the input x = 2 is duplicated.

i.e. at x = 2, y = 20 and at x = 2, y = 40

As we know that we can not have duplicated inputs as there should be only 1 output for each input.

Therefore, the given relation/mapping DOES NOT represent a function.

Determining the domain of a relation:

We know that the domain of the relation is the set of all the x-coordinates of the given points or ordered pairs.

Thus, the domain of the relation in ascending order is:

Domain D = {2, 3, 4}

Please note the duplicated elements in the domain or range of a relation are written only once.

Determining the range of a relation:

We know that the range of the relation is the set of all the y-coordinates of the given points or ordered pairs.

Thus, the range of the relation in ascending order is:

Domain D = {20, 30, 40}

write an equation in point slope form of the line that passes through the point (-8,-2) and had a slope of m=5

Answers

Answer:

5x - y + 38 = 0

Step-by-step explanation:

solution:

slope(m) = 5

(x1 , y1) = (-8 , -2)

we know that,

(y - y1) = m(x -x1)

or, (y - -2) = 5(x - -8)

or, y+2 = 5(x + 8)

or, y+2 = 5x +40

or, 5x - y + 38 = 0 is the required equation

In a orchestra , 10% the musicians play brass instruments. 15% play woodwin and, %5 play percussion .The other 28 musicians olay stringed insturments.

how many musicians are in the orchestra altogther? ​

Answers

Ok so basically 100% is the total amount of like percentage. It stand for 1 . But since you have 3 different percentages, you would use 100% instead.
Firstly, add up the percentages:
10%+15%+28% ( don’t worry about the percentage sign)
= 53% that would be the percentage of the musicians+Woodwind+percussion

28 other play stringed instruments, what you do is u want to change 53%to a normal number , so 53% is out of 100 , so 53/100x100= 53 , and 53+28= 81.

—There are 81 musicians altogether .

A hardware store rents vacuum cleaners that customers may use for part or all of a day before returning. The store charges a flat fee plus an hourly rate. Write a linear function for the total rental cost, f(x), of a vacuum cleaner after x hours of rental. *

Answers

Answer:

f(x) = bx + y

Step-by-step explanation:

Linear functions are very easy as you simply need to multiply the cost per hour (in this scenario) by the total number of hours that the individual is renting the vacuum for. Then you simply add any indpendent value such as the flat fee that the hardware store charges. We can use these values to create the following function.

f(x) = bx + y

where:

b = hourly rate

x = hours of rental

y = flat fee
