The output of the function y would be -3 if the input is 4. So, option D is the answer.
Here, the function rule that we have been provided with is ⇒ y = x - 7
Given, the input we need to use is ⇒ x = 4
We use the value of the given in the function rule to get the required output:
y = 4 - 7
y = -3
Therefore, after using the given input 4 and substituting it in the given function rule, we get the output -3.

The photography club is selling hot chocolate at soccer games to raise money for new cameras. The table shows their profit per game for the first five games.
Game Profit ($)
1 −12.50
2 −10.15
3 18.65
4 25.90
5 45.75
Based on the average profit per game, how much total money can the club expect to earn by the end of the 10-game season?
__ dollar(s)
Answer:
First, we need to take the average of the numbers. So, we will add 12.50, 10.15, 18.65, 25.90, and 45.75, getting us 112.95. Then we need to divide this by 5 to get the average profit for each game, getting us the number 22.59. Then we add up the money already earned with 22.59*5 (getting us 112.95 + 112.95), which gives us the number $225.9.
Hope this helps!
The total profit by the end of the 10-game season is $225.9.
How to calculate the average?In order to calculate average, divide the total sum of the data to the total number of data. An average is a standard number for a given data whose value can both be more or less than it.
The given problem can be solved as follows,
The average profit for the five games can be calculated by summing the profits all the five games and then dividing it by 5 as below,
(12.50 + 10.15 + 18.65 + 25.90 + 45.75)/5 = 112.95/5 = 22.59
Now, the profit for 10 games is the average profit multiplied by 10.
22.59 × 10 = 225.9
Hence, the total money the club can expect to earn by the end of the 10-game season is $225.9.

Answer:
(x, y) = (-3, -6)
Step-by-step explanation:
You want the solution to the system of equations 6 = -4x +y, -5x -y = -21 using the substitution method.
Expression for yAdding 4x to the first equation gives an expression for y:
6 +4x = y
SubstitutionThis can be substituted into the second equation:
-5x -(6 +4x) = 21
-9x -6 = 21 . . . . . simplify
-9x = 27 . . . . . . . add 6
x = -3 . . . . . . . . . divide by -9
6 +4(-3) = y . . . . . . . find y using the expression for y
6 -12 = -6 = y
The solution is (x, y) = (-3, -6).

A track team needed to run or jog 20 laps for their practice. Of the total 20 laps, Sara completed 45, Jamie completed 58, Keenan completed 59, Maya completed 0.833, and Trey completed 0.875. Identify the descending numeric order of the laps completed.
Answer:
59 keenan
58 Jamie
45 sara
0.875 trey
0.833 maya
The descending numeric order of the laps was completed as 59, 58, 45, 0.875,0.833
What is descending order?Descending order is defined as when numbers (or other items) are arranged from the largest numbers to the least numbers, it is said to be in descending order.
Sara finished 45 laps, Jamie completed 58, Keenan completed 59, Maya completed 0.833, and Trey completed 0.875.
We have the given numbers as:
45, 58, 59, 0.833, 0.875
we have to determine the descending order of given numbers
Here the largest numbers to the least numbers, it is said to be in descending order.
⇒ 59 > 58 > 45 > 0.875 > 0.833
Hence, the descending numeric order of the laps completed:
Keenan completed 59 laps
Jamie completed 58 laps
Sara completed 45 laps
Trey completed 0.875 laps
Maya completed 0.833 laps

Answer: It would be x = y-18
Step-by-step explanation:
When you line them up it would look like this
2,20
9,27
To get to 9 from 27 you would have to subtract 27 by 18 and you would get 9
To get to 2 from 20 you would have to subtract 20 by 18 and you would get 2.

Answer: 8,700
Step-by-step explanation:
lets say you have 500 animals, and you decide to get another 500, but you decide that you want an extra 500, and then your kid says that they want another 500 animals. You now have 2000 animals, but you also need 4000 chickens so you now have 6000 animals. Then you need 900 pounds of animal food, but 900 pounds is weird so you get an extra 100 to make your total 1000. But now you need 800 dogs so you now have 2800 animals.
4000 + (500 x 4) + 900 + 100 + 800 = 8,700
