Answer:
A
D
Step-by-step explanation:
The way that I would do this is by plugging in 2 values for x, double it then see what happens
Let's say 2
So when we plug in 2 for x we get
5*2=y
y=10
Then what happens when we double x?
Our new equation would be 10x
*we get this becase 5*2=10*
so we plug in to for y=10x and get y=10*2 which is 20. Our answer doubled and therefore the answer is A
Let's do the same thing for number 2 with the number 10
5/10=.5
Then when the value of x triples our new equation is 5/3x
we use this formula and get 5/(3*10)=5/30=1/6=.1666667
This is equal to dividing it by 3 which means the answer is D
