If x+y+z=0 what is the value of

I don't think that there's a unique answer, because it depends on the numbers you choose: for example, if you pick , then you have

But for example, if you if you pick , then you have

Even if you wanted to use formula, you can at most solve one variable in terms of the other two:

and thus

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8
