Question

Y is inversely proportional to x. When x = 9 and y= 8. Find y when x= 6

Answer 1

Step-by-step explanation:

Y=k/x

9=k/8

K=72

Y=72/6

Y=12

Answer 2

Answer:

For x = 6, the value of y is 12.

Step-by-step explanation:

Step 1 of 3

It is given that y is inversely proportional to x.

⇒ y ∝ 1/x

⇒ y = k/x . . . . . (1)

where k = proportional constant.

Step 2 of 3

For $x=9$ and $y=8$,

Substitute the values 9 for x and 8 for y in the equation (1) as follows:

⇒ 8 = k/9

⇒ 8 × 9 =k

⇒ k = 72

Step 3 of 3

Find the value of $y$ when x = 6.

Substitute the values 6 for x and 72 for k in the equation (1) as follows:

⇒ y = 72/6

⇒ y = 12

Therefore, for x = 6, the value of $y$ is 12.
