Audrey’s mother bought a large rectangular cake for Audrey’s 13th birthday party. The cake was cut into 32 equal pieces to be shared among Audrey, her school friends, and her two younger brothers. Audrey ate 1/16 of the cake, her friends ate 3/4 of the cake, and her two brothers together ate 1/3 of the remaining pieces of the cake. How many pieces of cake did Audrey’s brothers have?

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

answer: true

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
