Answer: 
Step-by-step explanation:
Given the following function:
You need to follow these steps in order to solve the exercise:
1. Substitute 
:
2. Now you need to apply the Quadratic formula. This is:
In this case, you can identify that:
Then, you can substitute these values into the formula:
3. Evaluating, you get:
4. You must choose the positive value. Then:
Standard Form looks like this:
Also, A cannot be negative and there are no fractions in Standard Form.
Now that we know the rules of Standard Form, let's get x and y on one side.
-2/3y = 2 + 8/15x
Subtract 8/15x from both sides.
-8/15x - 2/3y = 2
Multiply 2/3 by 5/5 to get a common denominator.
-8/15x - 10/15y = 2
Multiply everything by 15 to rid of the fractions.
-8x - 10y = 30
Multiply everything by -1 to make A positive.
8x + 10y = -30
8x + 10y = -30
-4x + 10y = -4
10y = 4x - 4
y = 2/5 x - 2/5 so slope = 2/5
-2 - 2x = 5y
5y = -2x - 2
y = -2/5 x - 2/5 so slope = -2/5
the slope is opposite so the lines are intersecting
answer is A.
Answer:
Step-by-step explanation: Substitute x-c for y in the ellipese equation. Then solve the resulting equation for x, with c as a remining unknown.
Pick the vaue of c that results in one value for x. That will correspond to the tangent-line situation.
hopefully this is right
