One yard of a ribbon costs 3 1/2 dollars. how much should one pay for 5/8 yards?

Multiply the cost per yard by the number of yards bought.

Change 3 1/2 to an improper fraction:

3 1/2 = 7/2

Now you have 7/2 x 5/8

Multiply the top numbers together and then the bottom numbers together:

(7 x 5) / (2 x 8) = 35/16

Now rewrite the improper fraction as a proper fraction:

2 3/16 which would be $2.19

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
