(Option 3)
Step-by-step explanation:
Let's take into account ΔABC.
A(-2, -2) B(-1, 1) C(3, 2)
This process is entirely trial and error. Try out the different transformations and see which one results the image from the preimage.
In this case, our transformation is (-x, y). Let's put this into trial and error:
[tex]A(-2, -2) \rightarrow A'(2, -2)\\B(-1, 1) \rightarrow B'(1, 1)\\C(3, 2) \rightarrow C'(-3, 2)[/tex]
Simply, the values we got for the image is the same as provided in the question. So we know that option 3 is the right answer.

Question 1 : given the replacement set {0,1, 2, 3, 4} . solve 5x - 6 = 9
Question 2: Given the replacement set {2, 3, 4, 5} . Solve 8x + 4 = 5x - 6
Answers
The solution to the equations are x = 3 and no solution in the set, respectively
How to solve the equations using the replacement sets?Question 1
The equation is given as:
5x - 6 = 9
The replacement set is given as
{0,1, 2, 3, 4}
So, we replace the variables using the elements in the replacement set
When x = 0, we have
5(0) - 6 = 9
- 6 = 9 -- false
When x = 1, we have
5(1) - 6 = 9
- 1 = 9 -- false
When x = 2, we have
5(2) - 6 = 9
4 = 9 -- false
When x = 3, we have
5(3) - 6 = 9
9 = 9 -- true
Hence, the value of the equation is x = 3
Question 1
The equation is given as:
8x + 4 = 5x - 6
The replacement set is given as
{2, 3, 4, 5}
So, we replace the variables using the elements in the replacement set
When x = 2, we have
8(2) + 4 = 5(2) - 6
20 = 4 -- false
When x = 3, we have
8(3) + 4 = 5(3) - 6
28 = 9 -- false
When x = 4, we have
8(3) + 4 = 5(4) - 6
28 = 14 -- false
When x = 5, we have
8(5) + 4 = 5(5) - 6
44 = 19 -- false
Hence, the value of the equation is not in the solution set

suppose you walk at the of 210 ft/min. you need to walm 10,000 ft. how many more minutes will it take you to finish if you have already walked 550 ft.
Answers
It will take you 45 more minutes to finish walking the remaining distance.
If you have already walked 550 ft, subtracting it to the total distance you need to walk, then the remaining distance will be:
10,000 ft - 550 ft = 9450 ft
Rate is the relationship between two quantities of different units. Rate of speed is the amount of distance over total time.
If you walk at the rate of 210 ft/min, then the time it will take you to finish the remaining distance will be:
rate = distance/time
time = distance/rate
time = 9450 ft/(210 ft/min)
time = 45 mins
Hence, it will take you 45 more minutes to finish the walk.

What is the area of the shaded part of the figure
Answers
Answer: 102in
Step-by-step explanation:
the rectangle in the top right corners dimensions are 3in by 4in therefore that area is 12in then moving onto the larger rectangle the dimensions at the bottom are 10in and the dimensions for the side are 9in (6+3) so the area of the larger rectangle is 90. adding the two areas together gives a total shaded area of 102in
Answer: the area of the shaded part of the figure is 102in
Step-by-step explanation:
6+3=9 (length of the sides of the figure)
10+4= 14 (length of the bottom of the figure)
9x14 = 126 (area of entire figure)
4x6= 24 (area of the white part of the figure)
126-24 = 102 (area of the shaded part of the figure)

Given that,
A statement is 2 less than the quotient of a number y and 3.
According to question,
An algebraic expression can be written by use of 2 less than the quotient of a number y and 3.
To evaluate an algebraic expression is to determine its value when a certain number is used in lieu of the variable. In order to evaluate an expression, we first replace the variable with the supplied number, then we streamline the expression using the order of operations.
Here, expression is (y÷3)-2=(y/3)-2.
If we substitute the values 0,1,2,3,4...
We get the values between -7 and 4.
Therefore, the algebraic expression for the statement 2 less than the quotient of a number y and 3 is written as (y/3)-2.

QUESTION: William started with 40 pieces of candy and gave away x pieces. Hannah had 70 pieces of candy and gave away three times as many pieces as William did.
How many pieces of candy did William give away if they had the same number of pieces of candy left?
A. 30
B. 18
C. 15
D. 8
Answers
The pieces of candies that William gave away is 15.
How many pieces of candy did William give away?The linear expression that can be used to determine the number of candies left is:
Pieces of candies left = initial pieces of candies - number of candies given out
Pieces of candies left when William gave out candies : 40 - x
Pieces of candies left when Hannah gave out candies : 70 - 3x
If they have the same pieces of candies left, the two above expressions would be equal.
40 - x = 70 - 3x
3x - x = 70 - 40
2x = 30
x = 15

Got the answer to a already just need b
Answers
a) Number of points the team has is 18
b) Number of games lost by the team is 9
a) How many point does the team have?
Number of wins the team has = W= 5
Number of draws the team has = D= 3
Number of points of the team = P
The equation is given by,
P = 3W +D
P= 3*5 + 3
P = 15+3
P = 18
Number of points the team has 18 points
b) How many games has this team lost?
Number of points of the team =P = 50
Number of draws the team has = D= 14
Number of wins the team has = W
Number of matches played by the team =T= 35
The equation is given by,
P = 3W +D
50 = 3W+ 14
3W = 50- 14
3W = 36
W = 12
Rewriting as equation,
Lost matches = Total matches - (Win matches+ Draw matches)
= T - (W+ D)
= 35 - (12+ 14)
=35 - 26
= 9
Number of games lost by the team = 9

To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue.
We have been given that
x(x - 3) = -1 ....... eq(1)
Find out the value of
x³(x³ - 18) ........eq(2)
We first simplify the value of x in equation (1)
x(x−3)=−1
Divide by x on both side
x(x−3)/x = −1/x
(x−3)=−1 /x
Rewrite as
x + 1/x = 3
Taking cube on both sides
(x + 1/x)³ = 3³
x³ + (1/x)³ = 27 - 3×3
x³ + (1/x)³ = 27 - 9
x³ + (1/x)³ = 18
Multiply by x³
x^6 + 1 = 18x³
