Answer the following Calculate discounts in multiples of 5% on amounts of money
If 5% of £30 is £1.5 what is:
40% £
15% £
75% £
55% £
30% £

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
