Al has a roll of 4 feet (48 inches) of ribbon. How many 8-inch pieces can he cut from the roll? A2
B5
C6
D8

6

Step-by-step explanation:

From the question, we are informed that Al has a roll of 4 feet which is 48 inches of ribbon. To calculate the number of 8-inch pieces can he cut from the roll, we have to divide the total roll which is 48 inches divided by 8 inches. This will be:

= 48 inches/8 inches

= 6

Therefore, Al can cut 6 8-inch pieces from the roll.

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: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
