Ruben put an empty cup underneath a leaking faucet. After 1 hours, Ruben had collected cup of water. What is the 2

rate, in cups per hour, at which the water is leaking from the faucet?

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:

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

m∠a is 90°

m∠b is 40°
