Jan needed to empty 18 gallons of water from a tub into jugs that hold 0.5 gallons of water. how many jugs did jan need?

divide 18 by 0.5

18/0.5 = 36

36 jugs are needed

no, because the sides are not congruent

  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.
