Question

3] y propto x,y=2 when x = 6 find x when y = 5​

Answer 1

Step-by-step explanation:

x 36 12 9 3

y 2 6 8 24

Given proportionality is x∝

y

1

∴x=k

y

1

(where k is a constant of variation)

∴k=xy ...(1)

Substituting x=36 and y=2 in equation (1),

k=36×2=72

(a) When x=12, k=72, y=?

y=

x

k

=

12

72

=6

(b) When y=8, k=72, x=?

x=

y

k

=

8

72

=9

(c) When y=24, k=72, x=?

⇒x=

y

k

=

24

72

=3....

bhai it's ur 2nd I'd na
