Hi i have lots of these problems, you think you can tell me what the answer is? I just need this one solved to learn off of. ( if you are gonna be rude please dont say a thing and carry on with whatever activity that you have to do in your life ;D )
1. Which of these equations does NOT represent a direct proportion?
A, 5y = 4x
B, Y = x/3
C, X + 1
D, y=0.5x
direct proportion means of form y = constant * x
It does NOT mean a sum like y = x + 1
So C?
yes
Thank you so much man! Maybe I wont fail!
Of course, I'm here to help you! Let's figure out which equation does not represent a direct proportion.
In a direct proportion, as one variable increases, the other variable also increases proportionally, or as one variable decreases, the other variable also decreases proportionally.
To determine if an equation represents a direct proportion, we need to check if the equation can be written in the form y = kx, where k is a constant.
Let's go through each equation and see if it satisfies the criteria:
A. 5y = 4x
Here, we can write it in the form y = (4/5)x, so this equation represents a direct proportion.
B. y = x/3
This equation is already in the form y = (1/3)x, which represents a direct proportion.
C. x + 1
This equation is not in the form y = kx, which means it doesn't represent a direct proportion.
D. y = 0.5x
This equation can be written as y = (1/2)x, which represents a direct proportion.
So, the equation that does not represent a direct proportion is C, x + 1.
I hope this explanation helps you understand how to identify direct proportions in equations! If you have any more questions, feel free to ask!
