Cole made 5 necklaces for his mom
with 12 seashells on
each. Then his sister
wanted one. How
many shells did he
use in all?

72

Step-by-step explanation:

His Mom got 5 necklaces with 12 shells each, so Cole used 5x12=60 shells on her necklaces. He then made one more for his sister, using another 12 shells. In total, he used 60 shells for his mom's necklaces and 12 for his sister's, equalling (60+12)=72.

  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.
