Simplify the numerical expression. 2)^2

i dont know

step-by-step explanation:

why didnt you study

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= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

i think this is a open ended question but i agree with other guy who said you should ask it at english section
