Please answer with the correct answers, or just tell me how to solve it please!
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
a direct proportion is of the form y=kx
where k is some constant value.
y = x+1 does not fit that pattern. The "+1" gets in the way.
A is y = 4/5 x
B is y = 1/3 x
D is already in the desired format, with k = 0.5
Can you explain further? i still dont get it.
hey oobleck can you help with science check newest Tiger tried to help but didn't know the answers please help thank you
ill be back later to check if anyone helped byee i may come back at 8:30
To determine which equation does NOT represent a direct proportion, we need to understand what a direct proportion is.
In a direct proportion, as one variable increases, the other variable also increases at a constant rate. This means that the ratio between the two variables remains constant.
Now, let's analyze each equation to identify the direct proportion:
A. 5y = 4x
This equation has a constant ratio of 5/4, showing a direct proportion between y and x.
B. y = x/3
The ratio between y and x in this equation is 1/3, indicating a direct proportion.
C. x + 1
This expression does not show a direct proportion because there is no relationship between x and another variable. It is not an equation but an expression.
D. y = 0.5x
The ratio of y to x in this equation is 1/2, suggesting a direct proportion.
Thus, the equation that does NOT represent a direct proportion is C, x + 1.
