Nellie has a new beaded necklace. 2 out of the 40 beads on the necklace are blue. What percentage of beads on Nellie's necklace are blue?

5%

Step-by-step explanation:

2/40 = 1/20

1/20 = 0.05

0.05 = 5%

  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.
