Taking test need ! tom had $56. he bought a soda for $2 and 2 cookies for $3. which expression correctly shows the total money tom has left? (1 point) a $56 + (−$2) + (−$3) b $56 + (−$2) − (−$3) c $56 − (−$2) − (−$3) d $56 − (−$2) + (−$3)

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:

the answer is 45 i just did it on oddesy ware
