Hiya! I am on a test and I am having serious trouble with this problem, Think you can answer it? Thanks a billion!
Which of these equasions doesn't represent a direct proportion?
[Note: 1/2 is how ill be writing fractions!]
A, 3/4Y = 6X
B, Y = 9/X
C, Y/X = 5
D, 2Y = X
Only answer if you have the answer please!
Someone help please!
B looks like a winner
boy - impatient much?
reposted within 4 minutes of asking. <smh>
Bruh stop being so dramatic “ impatient much” we know your the worst, but jeez try acting good for once.
O.o
Oop-
Of course! I'd be happy to help you with this problem. To determine which equation doesn't represent a direct proportion, we need to understand what a direct proportion is.
In a direct proportion, as one variable increases or decreases, the other variable also increases or decreases in the same ratio. In other words, if we increase one variable by a certain amount, the other variable will also increase by the same ratio.
Now, let's examine each equation and see if it represents a direct proportion:
A) 3/4Y = 6X: This equation has the variables Y and X on opposite sides of the equation. In a direct proportion, the variables should be on the same side. Therefore, this equation does not represent a direct proportion.
B) Y = 9/X: This equation has the variables Y and X on the same side of the equation. As X decreases, Y increases in the same ratio (9/X). This equation represents a direct proportion.
C) Y/X = 5: This equation also has the variables Y and X on opposite sides of the equation. Similar to equation A, the variables should be on the same side for a direct proportion. Therefore, this equation does not represent a direct proportion.
D) 2Y = X: This equation has the variables Y and X on opposite sides of the equation. Again, the variables should be on the same side for a direct proportion. Therefore, this equation does not represent a direct proportion.
So, the equation that does not represent a direct proportion is option A, 3/4Y = 6X.
