A) y=5/x what happens to the value of y if the value of x triples

The value of y becomes 1/3 of the original.

Step-by-step explanation:

y = 5/x

The value of x tripling is same as dividing both sides by 3.

y/3 = (5/x) / 3

y/3 = 5/3x

1/3y = 5/3x

Let's check.

Put x as 10 in the original equation.

5 / (10)

1/2

Put x as 10 in the new equation.

5/3 (10)

5/30

1/6

1/6 is one-third of 1/2.

1/2 * 1/3 = 1/6

Y is going to triple (y1=3y)

Step-by-step explanation:

y=5/x;

x triples means y1=5 / (3x);

Y1 divided by y, we get (5/x) / (5/3x) = (5/x) * (3x/5) = 3
