Select the correct answer. tony is taking inventory in a warehouse. he's counting tennis shoes. there are 43 pairs of women's tennis shoes and 39 pairs of men's tennis shoes. how many pairs of tennis shoes are there in all? a. 72 pairs b. 76 pairs c. 80 pairs d. 82 pairs

D. 82 Pairs

43+39= 82. therefore your answer is 82.

:)

D. is the answer.

There are 43 pairs of women's tennis shoes and 39 pairs of men's tennis shoes.

43 + 39 = 82

Therefore there are 82 pairs of tennis shoes in all

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 mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
