Step-by-step explanation:
Given:
There are given the equation:

Explanation:
From the equation (1):
Put the value of x into the equation (2):
So,
From the equation (2):

Now,
Put the value of y into the equation (1):
So,
From the first equation:

Final answer:
Hence, the ordered pair of the solution is shown below:
Answer:
The revenue would be $ 440
Step-by-step explanation:
Consider the correct complete question is,
"Roundup Rackets restrings a tennis racket for $22. If the store restrings 20 rackets each month, what is the monthly revenue from restringing rackets."
Thus,
The price for restrings each tennis racket = $ 22,
Number of rackets re stringed in a month = 20,
Hence, the monthly revenue = price of restrings each tennis racket × number of rackets re stringed
= 22 × 20
= $ 440
Given:
The inequality is:

To find:
The solution of the given inequality.
Solution:
We have,

Multiply both sides by 3.

Divide both sides by -8 and change the sign of inequality.


It can be written as:

Therefore, the correct option is A.
Answer:
0 - 20
1 -22
5 - 30
10 - 40
15 - 50
20 - 60
Step-by-step explanation:
The initial amount this equation is 20 so that is why at 0 shirts its still 20 dollars for the set up fee and 2 dollars per shirt. Now that we have this information we can actually make a linear equation
y = 2x + 20
y = the total cost
x = the number of shirts
All you have to do next is plug in the number of shirts to get the total cost
Example: 2(1) + 20 = y
2 + 20 = y
22 = y
Meaning for 1 shirt it would be 22 dollars in total
