So AD = DC
8x - 4 = 3x + 1 {add 4 to both sides}
8x = 3x + 1 + 4
8x = 3x + 5 {subtract 3s from both sides}
8x - 3x= 5
5x = 5 {divide both sides by 5}
x = 5/5
x = 1

2x+2yequals 5, x-2y equals 3 find the solution set by using method elimination by substitution
Answers
The solution set of the given system of equations is {(8/3, -1/6)}.
We are given the following system of linear equations:
2x + 2y = 5 ...(1)
x - 2y = 3 ...(2)
We can use the method of elimination by substitution to solve this system. First, we solve equation (2) for x in terms of y:
x = 2y + 3
Substituting this value of x in equation (1), we get:
2(2y + 3) + 2y = 5
Simplifying the above expression, we get:
6y + 6 = 5
6y = -1
y = -1/6
Substituting this value of y in equation (2), we get:
x - 2(-1/6) = 3
x + 1/3 = 3
x = 8/3
Therefore, the solution set of the given system of equations is:
{(8/3, -1/6)}

Rectangle WXYZ was dilated using the rule Rectangle W X Y Z is dilated to form rectangle W prime X prime Y prime Z prime. The length of W X is 5 and the length of X Y is 4.. D Subscript Z, twelve-fifths What is W'X'
Answers
The length of W'X' is 12 units.
For given question,
The Preimage of the dilation is rectangle WXYZ
The image formed after the dilation is W'X'Y'Z'
We need to find the measure of W'X'
The probable rule for the dilation obtained from a similar question is \(D_{z,12/5}\)
The center of dilation is the vertex Z
The scale factor of the dilation is 12/5
⇒ W'X' = (12/5) × WX
The length of W X is 5
⇒ W'X' = (12/5) × WX
⇒ W'X' = (12/5) × 5
⇒ W'X' = 12 units
Therefore, the length of W'X' is 12 units.

the length of a rectangle is 11 less than three times the width, and the area of the rectangle is 42. find the dimensions of the rectangle.
Answers
The dimensions of the rectangle are length and width are 6 and 11.6 respectively.
L = 3w - 11 ,
where,
L = length of the rectangle and
W =width of the rectangle
A=LW
Here A is Area of the Rectangle which is product of its dimensions i.e., length and breadth.
LW = 42
substituting for l:-
(3W-11)W= 42
3W^2 - 11W - 42 = 0
(3W + 10)(W - 6) = 0
W = 6 or -10/3 (ignore the negative root)
So the width is 6 and the length is 70/6= 11.6
The rectangle's length and width are therefore 6 and 11.6, respectively.

En una reunión, se observa que el total de va-

encuentran el total de mujeres y los varones
que no bailan?
O 3 a 7
O 5 a 2
O 23 a 7
O 4 a 17
O 7 a 3
Answers
The total number of women is in the ratio of 7: 3 of the total number of males who do not dance.
Hence, the answer is O 7 a 3.
Given that in a meeting the total number of males is to the number of females who do not dance as 7 is to 3 and for every 2 females who dance, a male does not dance.
We have to determine the relationship between the total number of women and the males who do not dance.
Solution: Let the number of males be 7x, and the number of women who do not dance be 3x.
Now, the total number of people present at the meeting is:
7x + 3x + 2n
where n is the number of women who dance.
The total number of males who do not dance is 2n / 1.
2n = 2n / 2
Therefore, the total number of males is:
7x + 2n / 2
This is equal to the total number of women:
3x + n
Dividing the two, we get:
(7x + 2n / 2) / (3x + n)= (14x + 4n) / (6x + 2n)
= 7x + 2n / 3x + n
Multiply both sides by (3x + n), we get:
7x (3x + n) + 2n
= 21x² + 7xn + 2n
= 7n (3x + 1)
Therefore, the total number of women is in the ratio of 7: 3 of the total number of males who do not dance. Hence, the answer is O 7 a 3.

To find:
The cost price of coat after the sale
Solution:
Cost price of coat = $65
Percentage of discount = 15%
The amount of discount will be 15% of the price of the coat.
Amount of discount :
\(=\frac{15}{100}\times \$65 \\=\$9.75\)
The cost price of the coat:

The dot plot with the least number of sites has the least frequency
The dot plot has the least number of sites is the Shield Darter
How to determine the dot plot?To determine the dot plot with the least number of sites, we simply calculate the total frequency of each dot plot
So, we have:
Shield Darter = 3 + 1 + 4 + 2 + 3 + 1 + 1
Shield Darter = 15
Calico Crayfish = 1 + 1 + 3 + 4 + 1 + 2 + 4 + 2
Calico Crayfish = 18
Zebra Mussel = 1 + 3 + 2 + 5 + 1 + 1 + 2 + 3 + 2
Zebra Mussel = 20
Blue back Herring = 3 + 3 + 2 + 1 + 3 + 1 + 4
Blue back Herring = 17

The y-coordinates are the same for both points but the x coordinates are different. This signals a no-slope line, or a line where the slope is 0. Even if we apply the formula, which is \(\frac{y_2-y_1}{x_2-x_1}\), it still ends up with 0.

Q.4 What is the difference between price floors and price ceiling? Give example and illustrate graphically in support of your answer.
Answers
A price floor is a law that limits the minimum price at which a good, service, or factor of production can be sold while a price ceiling is a regulation that limits the maximum price at which a good, service, or factor of production can be sold
Price floors are commonly implemented to support producers, while price ceilings are typically put in place to protect consumers from higher prices that might result from shortages or monopolies.
Example of Price Floor:Agricultural subsidies are a common example of price floors. Government price floors ensure that farmers receive a minimum price for their crops.
If the market price of wheat falls below the government-established price floor, the government may buy the excess supply at the guaranteed price, ensuring that farmers are able to make a profit. If there is a price floor, the minimum price is set above the equilibrium price.
