Answer:
x= (4,-7)
y= (6,-10)
z= (7,-4)
Step-by-step explanation:
1. By the chain rule,
I'm going to switch up the notation to save space, so for example, is shorthand for .
We have
Similarly,
where
To capture all the partial derivatives of , compute its gradient:
2. The problem is asking for and . But is already a function of , so the chain rule isn't needed here. I suspect it's supposed to say "find and " instead.
If that's the case, then
as the hint suggests. We have
Putting everything together, we get

Done
Answer:
z = 0
Step-by-step explanation:
3 (z + 7) = 21
3z + 21 = 21
3z = 0
z = 0
