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

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
