One stick is 9cm longer than the other 2/5 of the longer stick is equal to 1/2 of the shorter stick. Find the length of the longer stick

Length of the longer stick = 45 cm

Step-by-step explanation:

Let the length of shorter stick be x cm

Therefore, length of longer stick = (x + 9) cm

According to the given information:

Length of the longer stick = 45 cm

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
