Answer:
Step-by-step explanation:
For example, the atmosphere mixes down into the other spheres and releases precipitates; the hydrosphere overlaps onto land surfaces and water vapor rises up into the atmosphere; the biosphere reaches up into the atmosphere, down into soils and rock, and throughout the oceans, exchanging gases, water and nutrients
15/y+11-10/y+3=0
15/y-10/y=5/y 11+3=14
5/y+14=0
o-14=-14
5/y=-14
y=-5/14
What's the question? Also, grammar would be nice.

Answer:
The equation of hyperbola : 
Step-by-step explanation:
Given - This hyperbola is centered at the origin.
Foci: (0,-9) and (0,9) Vertices: (0,-7) and (0,7)
To find - Find its equation.
Solution -
We know that,
Equation of Hyperbola is represented by

Now,
Given that,
Foci : F(0, -9) and F'(0, 9)
So,
c = 9
And
Vertices : A(0,-7) and A'(0,7)
So,
a = 7
Also, we know that,
c² = a² + b²
⇒b² = c² - a²
⇒b² = 9² - 7²
⇒b² = 81 - 49
⇒b² = 32
So,
The equation of hyperbola becomes
