Answer:
See below.
Step-by-step explanation:
It's been a long time but I can give you some help on this.
The first step would be to divide both sides by (x^2 - 9).
Then it is a first order linear differential equation which you might have to solve by using an integrating factor.
Sorry I can't help more.

Answer:
A. The first one
Step-by-step explanation:
Because it has a negative slope and if you follow the line you can tell it has a slope of -1/4.
You want to find each coordinate of each part of the arrow, so let's do the arrow's point,
It looks like the coordinates for each of those points (1,-3) for Figure S, and (2,-6) for Figure T.
As you may know, coordinates are (x,y), you can see that Figure S' x coordinate is 1, and Figure T's x is 2.
1 times "2" is 2!
Same for the y on each, -3, and -6,
-3 times "2" is -6!
So therefore, this figure is dilated by two. Your answer is A!
Answer:
1: 90º
2: 25º
Step-by-step explanation:
<em>Hey there!</em>
Well we know that all the middle angles are 90º right angles,
so we can conclude that angle 1 is 90º.
All the angles in a triangle add up to 180 so we can set up the following,
65 + 90 + x = 180
Combine like terms
155 + x = 180
-155 to both sides
x = 25º
So angle 2 is 25º.
