Richard has 3 times as many music cds as benny does. if richard has y cds, the number of cds benny has is given by the expression

Benny would have 1/3y CDs.

Step-by-step explanation:

In order to find this, we know that Richard has 3 times the amount of CDs Benny does. Therefore, conversely, we must know that Benny has 1/3 of the CDs that Richard does. Knowing that Richard has y CDs allows us to model the amount for Benny as 1/3y.

Answer : The expression of the number of CDs Benny has,

Step-by-step explanation :

As we are given that the Richard has 'y' CD's. Now we have to determine expression of the number of CDs Benny.

Richard has number of CDs = y

As per question, Richard has 3 times as many music CDs as Benny. That means,

Let the Benny has number of CDs be, 'x'

So, the expression will be:

Thus, the expression of the number of CDs Benny has,

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
