The dependent variable is y, that represents the years
The common ratio is divide by 10 each time
Answer:
z=50
Step-by-step explanation:
Additive inverses are two numbers that have a sum of zero. Additive inverses can be represented on horizontal or vertical number lines by using arrows of equal length pointing in opposite directions.
Hopefully this helps!
If we substitute z = 2 - x - y in the last 2 equations it simplifies to 2 equations in x and y:=
x^2 + y^2 + xy - 2x - 2y = 5 and
-x^2 - y^2 - xy + 2x + 2y = -5
if we add these we get 0 = 0 so there are infinite solutions
