justina needs to dilate traiangle ABC using a scale factor of 1.5
Using the rule for a dilation, it is found that:
1. The table with the coordinates is given by the first image.
2. The graph of the dilated triangle is given by the second image.
3. The rule is: (x,y) -> (1.5x, 1.5y).
What is the effect of a dilation of a figure?When a figure is dilated by an scale factor of a, each vertex of the figure is multiplied by the scale factor of a, hence the rule is given by the following vector:
(x,y) -> (ax, ay).
The coordinates of the vertices of the pre-image are given as follows:
A(-2, -2), B(2,2), C(4, -2).
The dilation has a scale factor of 1.5, hence the rule for the calculation of each vertex of the image, considering the pre-image, is given as follows:
(x,y) -> (1.5x, 1.5y).
Then the vertices of the image will be given as follows:
A'(-3, -3), B'(3,3), C'(6, -3).
Each coordinate of A, B and C was simply multiplied by 1/2, and the triangle with these vertices is given by the second image at the end of the answer.
What is the missing information?The problem is incomplete, and is given by the first image at the end of the answer.

Find irrational number, which is more than 0,6(3) and less than 0,64.
An irrational number that lies between the two given ones, 0.6333.... and 0.64 is:
√7 - 2.01 =0.63575...
How to find an irrational number between the two given ones?Remember that an irrational number is a number that can't be written as the quotient between two integers.
Here we want to find two numbers between 0.6333 (where the 3 repeats infinitely) and 0.64
So we cold try to find a number like:
6.3349412490184...
Such that there is no pattern (because if there were a pattern, it would not be an irrational number).
An example of this can be, for example:
√7 = 2.64575...
This is an irrational number.
Now, if we subtract 2.01 from that we will get:
√7 - 2.01 = 2.64575... - 2.01 = 0.63575...
This is an irrational number and lies between the two given ones, then we conclude that √7 - 2.01 =0.63575... is a correct option.

x = -14/9 is the solution to the equation ( 7x + 6 )/4 = ( 2x − 3 )/5 in a simplified improper fraction form.
What is the value of x in the given equation?Given the data in the question;
( 7x + 6 )/4 = ( 2x − 3 )/5x = ?To solve for x, first we cross multiply
( 7x + 6 )/4 = ( 2x − 3 )/5
5( 7x + 6 ) = 4( 2x − 3 )

What value of c in the equation cx+4y=12 would give the equation a slope of 8?
Please provide all work and steps you used to find your answer, or the answer is pretty much useless. Thank you!
The value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.
What is the slope of a straight line?A straight line of the form y = MX + c has its slope as 'm'
It is constant for a line. The more the slope is, the steeper the line is.
Sign convention takes bottom left to top right going line as positive sloped. And that line which goes from bottom right to top left is taken to have a negative slope. The horizontal line has 0 slopes and the vertical line has an infinite slope, as it is now at maximum steepness.
We have been given the equation cx+4y=12 which has a slope of 8.
Also cx+4y=12
4y = 12 - cx
y = 12/4 - cx/4
y = 3 - cx/4
Then we know that straight line of the form y = mx + c
By comparing the formula;
y = 3 - cx/4
Slope = c/4 = 8
c/4 = 8
c = 8(4)
c = 32
Therefore, the value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.

What is an equation of the line that passes through the point (6,1)(6,1) and is parallel to the line x+3y=15
Answer:
Step-by-step explanation:
Let's write everything in slope-intercept format of y=mx+b, where m is the slope and b is the y-intercept.
x+3y=15
3y= -x + 15
y = (-1/3)x + 5
Parallel lines will have the sam slope, in this case -(1/3), So the new line will be:
y = (-1/3)x + b
We need to fijnd a value of b that will force the ine through point (6,1). Enter (6,1) in the equation and solve for b:
y = (-1/3)x + b
1 = (-1/3)(6) + b
1 = (-2) + b
b = 3
The parallel line is:
y = (-1/3)x + 3

A triangle is dilated by a factor of 2 and then rotated clockwise. Which statement about the triangle's image and pre-image is correct?
The correct statement about the triangle's image and pre-image is 'the image and pre-image are not congruent because one of the transformation is rigid transformation and the other is not.'
The correct answer is an option (1)
In this question, a triangle is dilated by a factor of 2 and then rotated clockwise.
We need to select the correct statement about the triangle's image and pre-image.
We know that rotation is a rigid transformation but dilation is not a rigid transformation.
Dilation does not preserve the size of the image.
Also, the image and pre-image are not congruent as the corresponding sides of triangle's image and pre-image are not equal.
Therefore, the correct statement about the triangle's image and pre-image is 'the image and pre-image are not congruent because one of the transformation is rigid transformation and the other is not.'

Answer:
D) 116
Step-by-step explanation:
Supplementary angles add up to 180°
∠CDE + ∠FDE = 180
3x + 10 + 6x + 8 = 180
3x + 6x + 10 + 8 = 180
Combine like terms,
9x + 18 = 180
Subtract 18 from both sides,
9x = 180 - 18
9x = 162
Divide both sides by 9
x = 162 ÷ 9

For every 3 lemons Chrissy buys at a farm stand,
the total cost increases by $1.80.
The constant of proportionality is ?
An equation that relates the total cost, y, and the
number of lemons, x, is y = ? x.
Use the equation you wrote to complete the table.
Table:
Numbers of lemons(x) | Total cost(y)
4 | _?__
_?__ | $4.20
_?__ | $9.00
18 | _?__
Answer:
The constant of proportionality is $1.80
y = 1.80x
Step-by-step explanation:
The constant of proportionality is $1.80
An equation that relates the total cost, y, and the number of lemons, x, is
y = 1.80x
where,
y =Total cost
x = number of lemon
When x = 4
y = 1.80x
y = 1.80(4)
y = 7.2
y = $7.2
When y = $4.20
y = 1.80x
4.20 = 1.80x
x = 4.20 / 1.80
x = 2 1/3
x = 2 1/3
When y = $9.00
y = 1.80x
9.00 = 1.80x
x = 9.00 / 1.80
x = 5
x = 5
When x = 18
y = 1.80x
y = 1.80 × 18
y = 32.4
y = $32.4

(a) what is the probability that the web site has fewer than 5 million visitors in a single day? if needed, round your answer to four decimal digits
The probability that the web site has fewer than 5 million visitors in a single day is 0.7293.
For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.
First, solve for the z-score using the formula below.
z-score = (x – μ) / σ
where x = individual data value = 5 million
μ = mean = 4.56 million
σ = standard deviation = 720,000
z-score = (5 million - 4.56 million) / 720,000
z-score = 440,000 / 720,000
z-score = 0.6111
Find the probability that corresponds to the z-score in the z-table. (see attached images)
z-score = 0.6111
Using interpolation of values,
probability = 0.7293

The exponential function that shows the amount of money paid for membership x months after the beginning of the year is given by y = 32(1.18)ˣ.
What are the types of exponential function?There are two possibilities for the exponential function: it can be increasing or decreasing. Being increasing means that as the value of x increases, the value of f(x) also increases; being decreasing means that as the value of x decreases, the value of f(x) also decreases.
Let y represent the amount of money paid for membership x months after the beginning of the year. Abby's gym membership will increase by 18% a month. This is an exponential function.She is currently paying $32 a month, hence:y = 32(1 + 0.18)ˣy = 32(1.18)ˣ
