Answer:
For 13: 13/30
Step-by-step explanation:
First simplify!
9x - 25 + 21x - 35 + 12 = 0
then simplify some more
9x + 21x = 30x
(-25) + (-35) + 21 + 12 = -13
30x - 13 = 0
now add 13 to both sides, 13 and -13 cancel each other out and it becomes
30x = 13
then you divide by 30 to get x by itself. 30 cancels itself out and you are left with 13/30 which doesn't simplify so that shod be your answer! I couldn't figure out 14 but I hope this helps!!!

Answer:
(-2, 1) and (6, 1)
Step-by-step explanation:
The standard form equations for a hyperbola are ...

The first form opens horizontally; the second opens vertically. Further, the center-focus distance 'c' is given by ...

The attached figure illustrates the relation between the various parameters and the features of the hyperbola.
__
<h3>7.</h3>
Using the above information and the information in the first attachment, we find ...
(h, k) = (2, 1)
a = 4, b = 2
The vertices are (h±a, k), so are (2±4, 1) = (-2, 1) and (6, 1).
