Answer:
(x, y) = (3, -1)
Step-by-step explanation:
The solution to the system of equations is the point where the lines intersect.
(x, y) = (3, -1)
Yes they do form a proportion since they both simplify to 6/11
Answer:
C. 
Step-by-step explanation:
The polynomial form that reveals most quickly the zeroes is the form of a product of binomials. That is:

Where
is the product function and
is the i-th root of the polynomial.
Hence,
resembles a form that is close to the form described above. The right option is C.
