Answer:
28.3
Step-by-step explanation:
Use the Pythagorean Theorem to solve for the answer. 10^2 + x^2 = 30^2
The major axis of the eclipse is 12 units long
The given parameters can be represented as:


See attachment for illustration
To solve this question, we make use of the following theorem
The distance between a point and the foci sums up to the major axis
This translates to:



Answer:
True. It could. Sorry my answer just has to be 20 characters long
To solve for y, isolate the variable to one side.
9x+3y=4
-9x -9x
~~~~~~~~
3y= -9x+4
~~~~~~~~
3y= -9x+4 (Divide both sides by 3)
y=-3x+4
