Answer:

Step-by-step explanation:
Give that:
the surface equation is 
from the family of traces in x = n given that
, the equation can be represented as :


This represents a family of hyperbola for all values of n expects that n = ± 1
So, if n = ± 1,
Then

(y-z) (y+z) = 0
y = ± z
So, for n = ± 1, it is a pair of line for y = z, y = -z
Answer:
77,540
Step-by-step explanation:
Since 3 is less than 4, we round down a ten. This comes out to 77,540.
113.1
(If it needs to be rounded)
Answer:
Y=3x+1
Step-by-step explanation:
1-7/0-2=-6//-2=3
y=3x
3x x 2 = 6-7= -1
y=3x-(-1)
