Jackie already owns 19 necklaces, and additional necklaces are priced at 1 for a dollar. How
much money does Jackie need to spend on new necklaces in order to own a total of 32
necklaces?

13 dollars

Step-by-step explanation: if she already has 19, you just need to subtract that from 32.

55

step-by-step explanation:

  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.
