Its actually the same length. I will choose B so that i can run slower
Answer:
B) y = 9 x has Proportionality Constant = 9
Step-by-step explanation:
Two quantities P and Q are said to be PROPORTIONAL if and only if:
P ∝ Q ⇔ P = k Q ⇔ 
Here, k = PROPORTIONALITY CONSTANT
Given : k = 9
Now, let us consider the given expressions in which x ∝y
y = 81/3 x
Here, 
So, here Proportionality Constant ≠ 9
y = 9 x
Here, 
So, here Proportionality Constant = 9
y = 3 x
Here, 
So, here Proportionality Constant ≠ 9
y = 1/9 x
Here, 
So, here Proportionality Constant ≠ 9
Hence, only y = 9 x has Proportionality Constant = 9
The answer is 327. Remember that when you multiply a number by ten, you move the decimal point to the right one place.
Hope that helped you.
The second 'p' is supposed to be 'e'. With that correction,
those letters can be unscrambled to spell " expand ".
Now it's your turn. Unscramble " Algerba ".
