Find the percent one number is of another ? 1.) what percent of 84 is 14 ? 2.) what percent of 64 is 24 ? 3.) 12 is what percent of 15 ?

Step-by-step explanation:

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:

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
