Answer 2

Answer:

a) y = 5x

b) y = 60

Step-by-step explanation:

y is directly proportional to x

This means that

y ∝ x

We can replace the ∝ symbol by using a constant k.

The equation now is:

y = kx

When y is 30, x is 6

Putting these two values in the equation,

30 = k×6

k = 30/6

k = 5

The equation is y = 5x

Putting x's value as 12,

y = 5×12

y = 60
