A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.

In the context of this problem, we have that each vertex of A'B'C'D' is obtained with the multiplication of each of the coordinates of ABCD by four.

For example, we have that vertex A has the coordinates A(1, -2), while the equivalent vertex A' has the coordinates of A'(4, -8).

Answer:

[tex]\sf m = -2\\\\y-intercept =\dfrac{-5}{4}[/tex]

Step-by-step explanation:

Slope and y-intercept of the line:

     Write the equation in slope y-intercept form: y =mx +c

Here, m is the slope and c is the y-intercpet.

To isolate y, add 8x to both side,

            -8x - 4y = 5

                   -4y  = 8x + 5

Now, divide the entire equation by (-4),

                        [tex]\sf \dfrac{-4y}{-4}=\dfrac{8x}{-4} + \dfrac{5}{-4}\\\\\\y = -2x -\dfrac{5}{4}[/tex]

Now, compare with y = mx +c

          [tex]\boxed{\sf m= -2}\\\\\\\boxed{\sf y-intercept=\dfrac{-5}{4}}[/tex]

Answer:

y-intercept = -5/4

slope = -2

Step-by-step explanation:

To quickly find the slope and y-intercept of a given linear equation, we can express it in the following form, called the slope-intercept form:

[tex]\boxed{y = mx + c}[/tex],

where:

m ⇒ slope

c ⇒ y-intercept

In order to take the given equation into the slope-intercept form, we have to  make y the subject of the equation:

[tex]-8x - 4y = 5[/tex]

⇒ [tex]-4y = 8x + 5[/tex]                 [Adding 8x to both sides of the equation]

⇒ [tex]y = -\frac{1}{4}(8x + 5)[/tex]              [Dividing both sides of the equation by -4]

⇒ [tex]y = -2 x - \frac{5}{4}[/tex]

Comparing the above equation with the slope-intercept form, we can see that m = -2 and c = -5/4.

Therefore, y-intercept = -5/4, and slope = -2.

Step-by-step explanation:

The revenue function for the cakes can be shown as: R(x1, x2, x3, x4, x5) = $9x1 + $12x2 + $4x3 + $5x4 + $8x5

The revenue function is described as  the total amount of money earned from selling a certain quantity of cakes.

We make the following  

Cake 1 sold =  x1

Cake 2 =  x2

Cake 3 = x3,

Cake 4 =  x4,

Cake 5=  x5.

The revenue generated from selling each cake is:

Revenue1 = $9 * x1

Revenue2 = $12 * x2

Revenue3 = $4 * x3

Revenue4 = $5 * x4

Revenue5 = $8 * x5

Total revenue = Revenue1 + Revenue2 + Revenue3 + Revenue4 + Revenue5

Total revenue = $9 * x1 + $12 * x2 + $4 * x3 + $5 * x4 + $8 * x5

Answer:

Unknown but formula (Check step by step solution)

Step-by-step explanation:

Without the image of the base of the crayon, I cannot determine the exact dimensions of the triangular prism or calculate the volume of a single crayon. However, I can give you a general formula for calculating the volume of a triangular prism and use it to find the total volume of wax needed to make a box of 8 crayons.

The formula for the volume of a triangular prism is:

Volume = (1/2) x base x height x length

where base is the area of the base of the triangular prism, height is the height of the triangular prism, and length is the length of the triangular prism.

Assuming all the crayons in the box have the same dimensions, let's say the base of the triangular prism has a length of L and a width of W. We can calculate the area of the base of one crayon as:

Base area = (1/2) x L x W

Since the crayon is 90 millimeters long, its height is 90 millimeters. Therefore, the volume of one crayon is:

Volume of one crayon = (1/2) x L x W x 90

To find the total volume of wax used to make a box of 8 crayons, we can multiply the volume of one crayon by the number of crayons:

Total volume of wax = Volume of one crayon x 8

Total volume of wax = (1/2) x L x W x 90 x 8

Total volume of wax = 360 x L x W

Again, without knowing the exact dimensions of the triangular prism, I cannot calculate the total volume of wax used to make a box of 8 crayons. But you can use the formula above and substitute the values of L and W based on the dimensions of the base of the crayon to find the answer.

1 2/3 yards is equal to 5 1/3 feet.

To convert from yards to feet, we know that 1 yard is equal to 3 feet. Therefore, we can calculate:

1 2/3 yards = (1 + 2/3) yards = (3/3 + 2/3) yards = 5/3 yards

Now, to convert yards to feet, we multiply by 3:

5/3 yards * 3 feet/1 yard = 15/3 feet = 5 feet

The equation for the parabola in the graph is the one in option C:

y = (-1/4)x² -2x - 7

Remember that a parabola with leading coefficient a and a vertex (h, k) can be written as:

y = a*(x - h)² + k

Here the vertx is at (-4, -3), then:

y = a*(x + 4)² - 3

And we can see that it passes through the point (0, -7), replacing that we will get:

-7 = a*(0 + 4)² - 3

-7 = a*16 - 3

-7 + 3 = a*16

-4 = a*16

-4/16 = a

-1/4 = a

The quadratic is:

y = (-1/4)*(x + 4)² - 3

Expanding that, we will get:

y = (-1/4)x² -2x - 4 - 3

y = (-1/4)x² -2x - 7

They are similar because AB is four more than ED, AC is three more than DF, and BC is three more than EF.

To determine if two triangles are similar, we need to compare the ratios of the corresponding sides.

In this case, the given information allows us to compare the lengths of the corresponding sides of triangle ABC and triangle DEF.

We have:

AB = 16 and ED = 12 (AB is four more than ED)

AC = 12 and DF = 9 (AC is three more than DF)

BC = 1 and EF = 9 (BC is three more than EF)

The corresponding sides are proportional because the ratios of the lengths are consistent:

AB/ED = 16/12 = 4/3

AC/DF = 12/9 = 4/3

BC/EF = 1/9

Since the ratios of the corresponding sides are the same, we can conclude that triangle ABC and triangle DEF are similar

The family traveled from Camp Carol to Phoenix at an average speed of approximately 84.44 kilometers per hour.

Speed is simply referred to as distance traveled per unit time.

It is expressed mathematically as:

Speed = Distance / time

Given that the family traveled 38 km from Camp Carol to Phoenix in 27 minutes:

Distance traveled = 38 kilometers

Time taken = 27 minutes

First, convert the time from minutes to hours:

Time taken = ( 27 / 60 ) hours

Time taken = 0.45 hour

We can now calculate the average speed using the above formula as follows:

Average speed = Distance / time

Average speed = 38 km / 0.45 h

Average speed = 84.44 km/h
