If x ∝ y² and y = 2a when x = a; x and y let us find the relation between x and y.

Let us write whether the following statements are true or false :

i. If non-zero constant.

ii. If x ∝ z and y ∝ z then y ∝ z

Let us fill in the blanks :

i. If and then x∝ _______

ii. If x ∝ y, xⁿ∝ ________

iii. If x ∝ y and x ∝ z, then (y + z)∝ ________

If x ∝ y, y ∝ z and z ∝ x, let us find the product of three non zero constants.

If and let us find if there be any relation of direct or inverse variation between x and z.
