Use the graph to answer the question. Graph of polygon ABCD with vertices at 1 comma negative 1, 3 comma negative 5, 7 comma negative 5, 5 comma negative 1. A second polygon A prime B prime C prime D prime with vertices at 1 comma negative 6, 3 comma negative 10, 7 comma negative 10, 5 comma negative 6. Determine the translation used to create the image. 5 units down 5 units up 1 unit down 1 unit up
Answer:
The translation used to create the image from polygon ABCD to polygon A' B' C' D' is 5 units down.
Step-by-step explanation:
You can see this by observing that all of the y-coordinates in A' B' C' D' are 5 units less than their corresponding y-coordinates in ABCD. Specifically, the y-coordinates of the vertices in ABCD are (-1, -5, -5, -1), and the y-coordinates of the vertices in A' B' C' D' are (-6, -10, -10, -6).
Therefore, the vertical shift or translation used to create the image is 5 units down.
Answer:
5 units down.
Step-by-step explanation:
To solve this question, we need to compare the coordinates of the corresponding vertices of the two polygons and see how they change. A translation is a type of transformation that slides a figure by a certain distance and direction without changing its size or shape. The rule of a translation can be written as (x, y) -> (x + h, y + k), where h and k are the horizontal and vertical shifts, we can see that:
A (1, -1) maps to A’ (1, -6), which means x stays the same and y decreases by 5.B (3, -5) maps to B’ (3, -10), which means x stays the same and y decreases by 5.C (7, -5) maps to C’ (7, -10), which means x stays the same and y decreases by 5.D (5, -1) maps to D’ (5, -6), which means x stays the same and y decreases by 5.We can see that all the vertices have the same change in their coordinates: x stays the same and y decreases by 5. This means that the translation used to create the image is 5 units down. The rule of this translation can be written as (x, y) -> (x, y - 5). Therefore, the answer is 5 units down.
Question 8!!
Total area= area of rhombus + area of triangle
Answer:
total area of the given figure is 126

1) 14×6+1/2×14×6
2) 84+42
3) =126
What is the area of Z?
Answer:
t = 5 kilometers
Step-by-step explanation:
From the given figure,
Perimeter = 18 kilometers
Now, the formula for perimeter of a rectangle = 2(l + b)
Where,
'l' is the length of the rectangle
and
'b' is the breadth of the rectangle.
Since length is the longest side of a rectangle, therefore from the given figure
=> l = t kilometers
and
=> b = 4 kilometers
Substituting values in the formula,
18 = 2(t + 4)
=> 18/2 = t + 4
=> 9 = t + 4
=> 9 - 4 = t
=> t = 5 kilometers
Answer:
5 km
Step-by-step explanation:
We know that the perimeter of this rectangle is 18km.
We also know that 1 side is 4km.
Given the perimeter formula:
[tex]P=2(l+w)[/tex]
We can substitute our given values:
18=2(4+w)
Solve the right side
18=8+2w
subtract 8 from both sides
10=2w
divide both sides by 2
5=w
This means that z, the width, is 5 km.
Hope this helps!

Answer:
Price per large envelope = $1.42 (option A)
Price of each postcard = $0.35 (not asked for in this specific question)
Step-by-step process for solution given below
Step-by-step explanation:
The first thing to do for this problem and other similar problems is to set up the system of linear equations to be solved
We start with the unknowns and provide variable names for these unknowns
There are two unknowns here - the cost of each postcard and the cost of each large envelope
Let
x = cost of one postcard
y = cost of one large envelope
Customer 1 bought 14 postcards(cost = 14x) and 5 envelops(cost = 5y) for a total cost of $12
We can set up this as an equation:
12x + 5y = 12 ............ [1]
Customer 2 bought 10 postcards(cost = 10x) and 15 envelops(cost = 15y) for a total cost of $24.80
This translates to the following equation:
10x + 15y = 24.80 .... [2]
Let's re-write these equations one below the other for easier solution:
[tex]\begin{amatrix}14x+5y=12\dots[1]\\ 10x+15y=24.8\dots[2]\end{amatrix}[/tex]
Solving by substitution:
From any one of the above equations, express one variable in terms of the other variable and substitute for that variable in the other equation to solve.
Take equation [1]
[tex]14x+5y=12[/tex]
Let's express x in terms of y.
Move 5y to the right:
[tex]14x=12-5y[/tex]
[tex]x =\dfrac{12-5y}{14}[/tex]
Use this expression in y for x in equation [2]
[tex]10x + 15y = 24.8\\\\\implies 10 \cdot \dfrac{12-5y}{14}+15y=24.8\\\\\implies \dfrac{\left(12-5y\right)\cdot \:10}{14} + 15y = 24.8\\\\\implies \dfrac{\left(12-5y\right)\cdot \:10}{14} + 15y = 24.8\\\\[/tex]
Multiply throughout by 14:
[tex]14 \cdot \dfrac{\left(12-5y\right)\cdot \:10}{14} + 14\cdot 15y = 14 \cdot 24.8\\\\(12-5y)10 + 210y = 347.2\\\\120 - 50y + 210y = 347.2\\\\120 + 160y = 347.2\\\\160y = 347.2- 120\\\\160y = 227.2\\\\y = \dfrac{227.2}{160}\\\\y = 1.42[/tex]
Substitute y = 1.42 in equation [tex]x=\dfrac{12-5y}{14}[/tex]
[tex]x=\dfrac{12-5\cdot \:1.42}{14}\\\\x = 0.35\\\\[/tex]
So the cost of each large envelope was $1.42 and cost of each postcard was $0.35
Answer is option A
Solve by elimination
The idea here is to get the coefficients of one of the variables the same in both equations by multiplying / dividing one or both of the equations by some factor and then add/subtract to isolate the other variable and solve
For equations 1 and 2 do the following
Subtract the equations:
[tex]70x+105y=173.6\\-\\70x+25y=\;\;\;\;\;60\\\\[/tex]
-------------------------------
[tex]80y=113.6[/tex]
y = 113.6/80 = 1.42 as before
Substitute for y in equation 1 and solve for x
14x + 5y = 12 => 14x + 5(1.42) = 12
=> 14x + 7.1 = 12
=> 14x = 12 - 7.1
=> 14x = 4.9
=> x = 4.9/14 = 0.35 as before
I personally prefer solving by elimination since solving by substitution involves heavy duty fractional expressions

Describe a rule for determining how much the store charges based on the number of turkey subs delivered.
The rule for determining how much the store charges based on the number of turkey subs delivered will depend on the pricing structure that the store uses. One possible rule is a linear function, where the cost of each turkey sub is a fixed amount and the total cost is proportional to the number of subs delivered.
For example, if the store charges $5 for each turkey sub, the rule could be:
Total cost = $5 per sub * Number of subs delivered
So if the store delivers 10 turkey subs, the total cost would be:
Total cost = $5 per sub * 10 subs = $50
If the store delivers 20 turkey subs, the total cost would be:
Total cost = $5 per sub * 20 subs = $100
This rule assumes that the cost per sub remains constant regardless of the number of subs delivered. However, in reality, the cost per sub may vary depending on factors such as the cost of ingredients and labor, and the store's desired profit margin.

Kyle has a storage box that is 2 ft. long, 3 ft. high, and has a volume of [tex]12ft^{3}[/tex]
Myla has a storage box that is 4 ft. high, 2 ft. long, and has a volume of [tex]16ft^{3}[/tex]
What are the widths of Kyle and Myla's boxes? Explain how you know.
help please! and please have easy explanation that's easy to understand :))
Answer:
OK so, volume= length x width x height
so, if the length of kyles box is 2, and his height is 3, but the volume is 12, then the width would be 2.
2 x 2 x 3=12
however, for myla, if her box is, 2 feet long and 4 feet high, but the volume is 16, then, her width is also 2.
2 x 2 x 4= 16
a way to look at this is, in the problem you are given the height and length, so, if its length times width times height, take your given length and multiply it by a number that will make it equal your given volume.
for example, let q=width, let m=height, and let j=length, p=volume, h=random variable.
j (x) h (x) m=p
its your job to find h.

A gardener uses a total of gallons of gasoline in one month. Of the total amount
of gasoline, was used in his lawn mowers. How many gallons of gasoline did the
gardener use his lawn mowers in one month?
Answer:
D. 36.9
Explanation:
three-fifths of 61.5 is 36.9!
Answer:
D. 36.9
Step-by-step explanation:
The total amount of gallons the gardener typically uses in a month is 61.5 gallons. Since the gardener used 3/5 gallons, we know that 5/5 is 61.5 gallons. So you would have to divide 61.5 by 5 in order to get 1/5 of the gallons which would be 12.3. Then you have to multiply the 12.3 by 3 in order to get 3/5 of how much the gardener used which is 39.9 gallons. I hope this helped!

Three park rangers had to report on the ways visitors use their facilities. Each ranger surveyed a sample of park visitors. Determine whether or not each sampling described is random or biased.
Answer:
To determine whether a sampling is random or biased, we need to know how the sample was selected. Here are three possible scenarios:
Ranger 1 stands at the entrance to the park and surveys the first 100 visitors who arrive.
This sampling is biased, as it only includes visitors who arrived early in the day. Visitors who arrive later in the day may have different characteristics or behaviors, so this sample may not be representative of all park visitors.
Ranger 2 selects every 10th visitor who enters the park and surveys them.
This sampling is random, as every 10th visitor is selected without bias. This method is called systematic sampling.
Ranger 3 surveys visitors who are leaving the park on a rainy day.
This sampling is biased, as visitors who come to the park on a rainy day may have different motivations or behaviors than visitors on a sunny day. This sample may not be representative of all park visitors.
In summary, sampling methods that are random, such as systematic sampling, are preferred over biased sampling methods in order to obtain a representative sample of the population of interest.
Answer: Depending on the situation
Step-by-step explanation: For a sample to be random, everyone/thing has to have an equal chance of getting selected. Ex. One of the park rangers asked everyone in one part of the park. - This example would be biased because the people who weren't in that part of the park had less of a chance of being picked

The rule is x→y=−2x. c Can you mark all the points that fit the rule on a coordinate plane?
Step-by-step explanation:
Y=0,-2,2
X=-1,0,1
Since x represent y = - 2x
The points that fit the rule on a coordinate plane are (0, 0), (1, -2), (2, -4) and (3, -6)
Selecting the points that fit the rule on a coordinate plane?From the question, we have the following parameters that can be used in our computation:
Rule: x→y=−2x
Express properly
So, we have the following representation
Rule: x → y = −2x
As an equation, we have
y = -2x
Next, we set values for x and calculate the value of y
Using the above as a guide, we have the following:
x : 0 → y = −2(0) = 0
x : 1 → y = −2(1) = -2
x : 2 → y = −2(2) = -4
x : 3 → y = −2(3) = -6
So, the points that fit the rule on a coordinate plane are (0, 0), (1, -2), (2, -4) and (3, -6)
