Answer:
The answers are:
(x,y,z)=
(5,1,-2)
(1,-2,5)
(-2,5,1)
(5,-2,1)
(-2,1,5)
(1,5,-2)
Step-by-step explanation:
In order to determine the answer, we have to express the final number into a addition.
The number 700070.07 may be written by:
700000+70+0.07
Then, we can express every number into a scientific notation,that is, at the form:
700000
a=7
b=5
70
a=7
b=1
0.07
a=7
b=-2
So, in this case, we have three numbers: 5, 1, -2. The set of values are the combination of these numbers, in total 6 set of numbers.
Finally, the possible set of values for x, y, z are:
(5,1,-2)
(1,-2,5)
(-2,5,1)
(5,-2,1)
(-2,1,5)
(1,5,-2)

Answer:
Hyperbola.
Step-by-step explanation:
We start from the function:
We may get the traces if we cut the surface in planes x=k. This is equivalent to replace x for k:
The last equation is the equation of an hyperbola, which varies its characteristics depending on K (the plane cut).
