Jack has c pieces of candy. he gives away 10 of the pieces. choose the expression that shows the number of pieces of candy jack has left.

C - 10 = x

Step-by-step explanation:

Jack starts off with c pieces of candy. He gives away 10 pieces of candy. This immediately becomes a subtraction problem. So far we have "c - 10". We are trying to find the number of pieces of candy Jack has left, so we need another variable. Let's use x:

c - 10 = x

Hope this helps,

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:

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
