Choose the expression that is equivalent to both −xy and x−y. xy
−(−xy)
−1(xy)
−x−y

-1(xy) exact value = -xy  

rewrite -1(xy) as -(xy)

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.

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
