To find the amount of solutions, you must find the discriminant. The discriminant is b^2 - 4ac. Number 6 has 2 solutions and number 7 has 1 solution.
Answer:
B
Step-by-step explanation:


Positive sine, negative tangent, means we have a negative cosine. We're talking about the second quadrant.



We know it's negative,

Answer: -(1/3)√5
Answer:

Step-by-step explanation:
The equation of a hyperbola centered at the origin with vertices on the y-axis is given by: 
The vertices of the hyperbola are the y-intercepts (0,12) and (0,-12)
This implies that:



The asymptote equation of a hyperbola is given by:

The given hyperbola has asymptote: 
By comparison; 


The required equation is:
