A light bulb consumes 3600 watts- hours per day. How many watt - hours does it consume in 5 days and 6 hours?

13500/3600= 3 days and 3/4 of a day

18,900 watt-hours for 5 days and 6 hours of use

10

step-by-step explanation:

7+3=10

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
