I am not sure exactly what you are looking for is this problem. Are you given choices from which to choose?
The empty set is a set with no numbers. Therefore, you should look for a set that doesn't have any elements.
Answer:
Step-by-step explanation:
Solve the inequality 5x − 4y > 20 for y, as follows: Subtract 5x from both sides, obtaining:
-4y > 20 - 5x;
Then divide all terms by -4:
y < -5 +(5/4)x, where the direction of the inequality sign has been reversed because of division by a negative quantity.
Temporarily replace the < symbol with = obtaining y = -5 +(5/4)x. Now choose at least three x values and find the corresponding y values. For example:
x y = -5 +(5/4)x
0 -5
4 0
-8 -15
Now plot these three points (0, -5), (4, 0) and (-8, -15). Draw a dashed line through them. Because of the < symbol in y < -5 +(5/4)x, shade the area underneath the dashed line.
So they move in together to be closer to each

is $22 marked up to $33
Ok, let us first analyze the given problem.
=> 22 dollars is said to be the original amount of money.
=> 33 dollars is the total marked up amount.
Now, we need to find out how many percent did the money increased
Solutions:
=> 33 dollars - 22 dollars = 11 dollars
=> 11 dollars / 22 dollars = 0.5 dollars
=> 0.5 dollars * 100% = 50%
Thus, the marked up money is 50%
