ANSWER
(3, 11) and (−3, −7)
EXPLANATION
The given system of equations are:

and

or

We equate the two equations to obtain,

We rewrite in standard quadratic form to obtain,

This simplifies to

We solve for x to obtain,




When


When x=-3,

Therefore the solution for the system is (3, 11) and (−3, −7).
It would be more than one because 3/5 + 3/4 equals 1 7/20
It is nonlinear because X is being raised to the second power
Answer:
-2
Step-by-step explanation:
Coefficient is usually the number in front of the variable so, in this case it would be -2.
