In {(-4, 3), (-2, 7), (-1,0), (4, -3), (11, -7)} function has an inverse that is also a function. Therefore, option A is the correct answer.
What is inverse function?Inverse function is represented by f⁻¹ with regards to the original function and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
We know that a function is only a function such that there is a unique value of y corresponding to x.
An inverse function will only be a function if the function which is going to be inverse is a function.
In {(-4, 3), (-2, 7), (-1,0), (4, -3), (11, -7)} all value of x corresponding to y are different but in all remaining options the values are repeating hence that will be not a function since only option A has to inverse.
Therefore, option A is the correct answer.

Eve is organizing a race to raise money for a local children's hospital. She makes $20 for each 5K participant and $45 for each 10K participant. Her goal is to raise $9,500.If x represents the number of participants in the 5K race and y represents the number of participants in the 10K race, the linear equation for the given scenario is
Answer:
20x + 45y = 9500 is the linear equation for given scenario
Step-by-step explanation:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
Therefore, the linear equation for given scenario is found
Answer:
20x + 45y = 9500
yes/no: no
Solution:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
If eve raises exactly $9,500, it is NOT possible for there to be 220 participants in the 5K race.

Twice one number is equal to one more than a second number. The sum of the numbers is five. Find the numbers
Answer:
2 and 3
Step-by-step explanation:
2 twice is 4 and 4 is one more than 3. 3 plus 2 is 5.
The two numbers are 2 and 3.
What are numbers?A number is a basic unit of mathematics. Numbers are used for counting, measuring, and comparing amounts. A number system is a set of symbols, or numerals, that are used to represent numbers.
Given that, Twice, one number is equal to one more than a second number. The sum of the numbers is five.
Let the numbers be a and b, establishing the equations,
2a = b+1
2a-b = 1........(i)
a+b = 5..........(ii)
Adding the equations, we get,
a = 2
b = 3
Hence, the two numbers are 2 and 3.

Step-by-step explanation:
They are 1^7 + 7C1 1^(7-1)(2x) + 7C2 1^5 (2x)^2 + 7C3 1^4 (2x)^3
= 1 + 14x + 21* 4x^2 + 35*8x^3

Maya adds 6 grams of sugar to a bottle containing 14 grams of warm water. What is the total weight of the sugar and water?
Answer:
The total weight of the sugar and water is 20 grams
Step-by-step explanation:
Given;
weight of sugar Maya added, w₁ = 6 grams
weight of water contained in the bottle, w₂ = 14 grams
The total weight of the sugar and water = 6 grams + 14 grams
The total weight of the sugar and water = 20 grams
Therefore, the total weight of the sugar and water in the bottle is 20 grams.

You have been asked to analyze the popcorn recipes of three different local theatres in order to figure out which theatre has the best popcorn. In this case, the "best" popcorn is the most buttery! In your quest to find the best, you meet with each theatre manager individually and ask for the ratio of oil to popcorn kernels that they use in their recipes. Here are their responses. The manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight. The manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week. The manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday. Find the ratio value of oil to popcorn kernels for Theatre A. Type your answer as a number. Theatre A's recipe calls for cup oil for every cup of popcorn kernels.

which table of values matches the equation y=2x-3
Answer:
What are the possible answer??/
Step-by-step explanation:
The set of points satisfying the equation y = 2x - 3 is a. {(0, -3), (1, -1), (1.5, 0), (2,1)}.
An equation is the combination of 2 or more expressions separated by the equality sign(=), signifying the equality of expressions.
To obtain the set of points satisfying the equation y = 2x - 3.
The given equation is y = 2x - 3.
Let's take x = 0,
y = 2 × 0 - 3 = -3,
the point is (0, -3).
Let's take y = 0,
0 = 2x - 3
2x = 3
x = [tex]\frac{3}{2}[/tex]
x = 1.5,
the point is (1.5, 0).
Let's take x = 1,
y = 2 × 1 - 3 = -1,
the point is (1, -1).
Let's take y = 1,
1 = 2x - 3
2x = 1 + 3
2x = 4
x = [tex]\frac{4}{2}[/tex]
x = 2,
the point is (2,1).
Hence, the set of points satisfying the equation is {(0, -3), (1, -1), (1.5, 0), (2,1)}.

Answer:
a and d = 32
Step-by-step explanation:
since ABC and DEF are similar m<A = m<D so you have the equation
5x + 12 = 8x
subtract 8x from both sides
5x + 12 -8x = 0
subtract 12 from both sides
5x -8x = -12
combine like terms
-3x = -12
devide by -3
x = 4
plug 4 into equation
5(4) + 12 = 8*4
20 + 12 = 32
32 = 32
