Line of reflection for the image vertices are A'(5, 1), B'(3, –1), and C'(7, –1) will be x = 2..
What is mean by Reflection?
Reflection is the process of taking the time to think deeply about the experiences, events, and choices that shape our lives. Reflection allows us to consider how our views and opinions have changed over time, and to take stock of our successes and failures. Reflection can also help us understand our personal values and beliefs and how we can use them to make more informed decisions in the future. Reflection involves looking inward and assessing our thoughts and feelings, as well as looking outward and considering our interactions with the world around us. Taking time for reflection can help us gain insight into our behaviors and motivations, as well as identify areas of our lives that need improvement. It can also help us stay mindful of our goals and stay on the path to achieving them. Reflection is an important part of personal growth and development, and can be a valuable tool for gaining self-awareness and increasing our emotional intelligence.
Given that;
After a reflection of the figure,
The image vertices are A'(5, 1), B'(3, –1), and C'(7, –1).
And, In the figure;
The vertices are A(-1, 1), B'(1, –1), and C'(-3, –1).
Now, When we take the reflection about the line x = 2.
Then, we get the image vertices are A'(5, 1), B'(3, –1), and C'(7, –1) of the vertices A(-1, 1), B'(1, –1), and C'(-3, –1).
Therefore, Line of reflection for the image vertices are A'(5, 1), B'(3, –1), and C'(7, –1) will be x = 2.

find M∠T explain your reasoning
Explanation:
Angle R = angle A = 41 since both angles involve a single arc marking.
Angle S = angle B = 74, both involve a double arc
For any triangle, the inside angles always add to 180 degrees.
R+S+T = 180
41+74+T = 180
115+T = 180
T = 180-115

"I have added screenshot of the complete question as well as the
diagram"
What is line segment ?
A line segment in geometry is a section of a straight line that is enclosed by two clearly defined end points and contains all of the points on the line that lie within those endpoints. The Euclidean distance between two endpoints of a line segment determines its length.
- In this diagram, line segment CD is the perpendicular bisector of line
segment AB
∴ AB ⊥ CD
∵ CD intersect AB at M
∴ M is the mid-point of AB
∴ The length of AM = the length of MB
- Assume the conjecture that the set of points equidistant from A
and B is the perpendicular bisector of AB is true
∴ Any point lies on the line CD equidistant from A and B
- If point E lies on the line CD
∵ CD is the perpendicular bisector of AB
∵ E lies on CD
∴ The length of EA = The length of EB
- From the figure point E is on the left side of the line CD
∵ Point A is on the left side of the line CD
∵ Point B is on the right side of the line CD
∵ Point E is on the left side of the line CD
∴ The length of AE < The length of BE
∴ Point E is closer to point A
Complete question: In this diagram, line segment CD is the
perpendicular bisector of line segment
AB. Assume the conjecture that the set of

a store has a 20% off sale on pants
The original price would typically be less expensive than the current price, though it is possible for the two to be equal in specific circumstances. The original price of the pants is $ 19
What was the original price of the pants?A store has 20% off sale on pants. With this discount, the price of one pair of pants before tax is $15.20.
n is the total price, 0.2n is the discount: n - 0.2n
n - 0.2n = 15.20
Step 2: Combine like terms
n - 0.2n = 15.20
0.8n = 15.20
Step 3: Divide both sides by 0.8
0.8n / 0.8 = 15.20 / 0.8

Find the standard form of an equation where a=1, and the vertex is at (-1,11). Find the x and y intercepts and graph the equation.
Answer:
y = [tex]x^2+2x+12[/tex] (x and y intercepts under "Step-by-step explanation" section)
Step-by-step explanation:
We can start by finding the vertex form and then expand it to the standard form.
The vertex form of the quadratic equation is
[tex]y=a(x-h)^2+k[/tex], where a is a constant and (h, k) is the vertex.
By plugging in 1 for a, -1 for h, and 11 for k, we have:
[tex]y=1(x-(-1))^2+11\\y=(x+1)^2+11[/tex]
Now we simply expand this vertex form to get the standard form:
[tex]y = (x+1)^2+11\\y=(x+1)(x+1)+11\\y=x^2+x+x+1+11\\y=x^2+2x+12[/tex]
We can find the x and y-intercepts using the vertex form.
To find the x-intercept, we plug in 0 for y:
[tex]0=(x+1)^2+11\\-11=(x+1)^2\\\sqrt{-11}=x+1;-\sqrt{11}=x+1\\ x_{intercepts}:(-1+\sqrt{-11}, 0); (-1-\sqrt{-11})[/tex]
The x-intercepts are non-real answers, so the quadratic equation never intersects the x-axis.
To find the y-intercept, we plug in 0 for x:
[tex]y=(0+1)^2+11\\y=1^2+11\\y_{intercept} =(0,12)[/tex]

What is a Hypothesis?In statistical hypothesis testing, the null hypothesis is a statement that represents the anticipated or "normal" outcome of a specific experiment. Unless there is evidence to the contrary, the null hypothesis, which is generally represented by the symbol "H0," is taken to be true.
A Type I mistake, sometimes known as a "false positive," arises when the null hypothesis is correct but is rejected based on the evidence. Applying a statistical test with a strong significance level increases the likelihood of rejecting the null hypothesis even when it is correct, which frequently leads to this mistake.

How to describe the correlation of the data?From the question, we have the following parameters that can be used in our computation:
Line of fit for a data set: -3x+4y=-5
Write out the equation of the line
So, we have
-3x + 4y = -5
Make y the subject of the equation
So, we have the following representation
y = 3/4x - 5/4
A linear equation is represented as
y = mx + c
Where
slope = m
This means that the slope of the equation is
m = 3/4
The above number is a positive number
Hence. the correlation is positive
