The resale value r) of a machine decreases at a rate proportional to the difference betweern the current price and the scrap value s. write a differential equation for r. if the machine sells new for $14,000, is worth $8000 in 4 years and has a scrap value of $1000, find an equation for the resale value at any time. r= 1000+13,000.(7/13)"4 or r=1000 +1 3000e-q155,

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
