Answer:
acute
Step-by-step explanation:q
There are infinitely many solutions.
Algebraically, we can eliminate
and try to solve for
:

Then



which is the equation of an ellipse.
Answer:
6/1 · 11/4 = 66/4 = 16 1/2
-10/3 · (-17/5) = 170/15 = 11 1/3
-9/2 · 26/3 = -234/6 = -39
11/6 · (-9/1) = -99/6 = -16 1/2
Divide 84.87 by 1.15, and you get 73.8
Then you can check your work by multiplying 73.8 by 1.15 and you get 84.87
