Answer:
C. (x, y) -> (x - 4, y + 5)
Step-by-step explanation:
A is at (2, -2)
A' is at (-2, 3)
To get from 2 to -2, you must subtract 4, so (x - 4)
To get from -2 to 3, you must add 5, so (y + 5)
(x - 4, y + 5)
I hope this helps :))
The algebraic description that maps ΔABC onto ΔA′B′C′ in the given figure should be option C. (x, y) -> (x - 4, y + 5)

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Answer: y = -1/4x - 6
Step-by-step explanation: the slope is -1/4 because slope = rise/run, the rise is 1, and the run is 4 and the slope is negative. the y intercept is -6 because it passes through -6 at the y axis.
Answer:
-1/4x + -6
Step-by-step explanation:
The slope is -1/4 because slope = \(\frac{rise}{run}\),
So:
-\(\frac{1}{4}\) is the slope, also is negative.
The y intercept is -6 because it passes through -6 at the y axis.

A plane traveled 756 miles each way to Baltimore and back. The trip there was with the wind. It took 7 hours. The trip back was into the wind. The trip back took 9 hours. What is the speed of the plane in still air? What is the speed of the wind?
Answers
Answer:
The speed of the wind is 12 miles per hour.
Explanation:
Let's call the speed of the plane in still air "p" and the speed of the wind "w".
From the given information, we know that:
756 miles = 7 hours * (p + w) (with the wind)
756 miles = 9 hours * (p - w) (against the wind)
We can simplify these two equations by dividing both sides by 7 and 9, respectively:
108 miles/hour = p + w
84 miles/hour = p - w
Now we can use a system of equations to solve for p and w:
p + w = 108
p - w = 84
Adding these two equations, we get:
2p = 192
Dividing by 2, we get:
p = 96
So the speed of the plane in still air is 96 miles per hour.
To find the speed of the wind, we can substitute p = 96 into either of the simplified equations:
p + w = 108
96 + w = 108
Subtracting 96 from both sides, we get:
w = 12
So the speed of the wind is 12 miles per hour.
Therefore, the speed of the plane in still air is 96 miles per hour and the speed of the wind is 12 miles per hour.

In a survey, a soft drink company asks people to name as many brands of soft drinks as they can. Which measure gives the most frequently mentioned brand? a. median b. mode c.mean
Answers
The required measure for the given case is mode. The correct option is (b).
How to find the mean and median for a given sample of data?In order to find the mean, first sum all the values of the data and count the number of data then divide them.
In order to find the median, first check whether the number of data is even or odd. For even number, the median is n/2 th element of the sample and for odd number the median is (n + 1)/2 th element.
The given problem deals with a sample of data.
In order find the correct answer, each option is analysed one by one as follows,
(a) The mean of a sample of data represents a standard value for the whole sample such that the individual values of the data may be more or less than it. but, it does not tell about the number of times a value is repeated.
(b)The median of a given sample can tell the middle most value of data when arranged in ascending order.
(c) The mode of a sample is about the times of occurrence of a single value in the whole sample.
As per the given question, to tell about the most frequently brand mode can be used.
Hence, the statistical measure that measures gives the most frequently mentioned brand is mode.

The graph shows two lines, A and B.
Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.
Part B: What is the solution to the equations of lines A and B? Explain your answer
Answers
Answer:
A: 1 solution
B: (4,4) is the solution
Step-by-step explanation:
They have different slopes so they're already different equations and because of that, they can only have one solution.
The intersection of the two lines is the solution since those coordinates satisfy both equations.
Answer:
Part AThe solutions of a graphed pair of equations are the points of intersection - the points on the graph where the two lines cross each other. At this point, when inputting the same x-value into the 2 equations, the resulting y-values will also be the same.
Therefore, from inspection of the graph, there is one point of intersection, and so one solution.
The name for a system that has one solution and intersects at one point is Consistent Independent
Part BFrom inspection of the graph, the point of intersection is (4, 4).
Therefore, the solution to the equations of line A and B is (4, 4).
Proof
Equation of line B: y = xEquation of line A: y = -0.5x + 6Using substitution:
⇒ x = -0.5x + 6
⇒ 1.5x = 6
⇒ x = 4
Substituting the found value of x into one of the equations to find y:
⇒ y = 4
Therefore, the solution is (4, 4)

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answers
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

Answer: The perimeter of crater lake is 17.27 miles.
Step-by-step explanation:
The shape of the lake is like a circle
The diameter of lake = d = 5.5 miles
∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles
Let The perimeter of crater lake = p miles
Now, As we know
The perimeter of circle = \pi × diameter
the value of \pi = 3.14
Or, p = pi × d
Or, p = pi × 5.5 miles
Or, p = 3.14 × 5.5 miles
∴ p = 17.27 miles
So, The perimeter of circle = perimeter of lake = p = 17.27 miles
Hence, The perimeter of the crater lake is 17.27 miles.
