Answer:
x=2,y=−1
Step-by-step explanation:
Solve for y in the first equation.
y=−9x/11+7/11
0=−2y+10−6x
Replace all occurrences of y with −9x/11+7/11 in each equation.
0=−48(x−2)11
y=−9x11+711
Solve for x in the first equation.
x=2
y=−9x/11+7/11
Replace all occurrences of x with 2 in each equation.
y=−1
x=2
The solution to the system is the complete set of ordered pairs that are valid solutions.

Answer:
g(2) = 27 is the answer.
Step-by-step explanation:
If the function is g(x) = (5 - x)³
By expanding (5 - x)³ = 5³-3.5²x + 15x² -x³
g(x) = 125 - 75x + 15x² - x³
Now g(2) = 125 - 75×2 + 15×(2)² - 2³
g(2) = 125 - 150 + 60 - 8
= -25 + 60 - 8
= 35 - 8 = 27
Or directly putting the value x = 2 in g(x) we get
g(2) = (5 - 2)³ = 3³ = 27
Therefore g(2) = 27 is the answer.

determinant: 
(a) 
D<0 means there are no real roots. there are two complex roots with imaginary components.
(b) D=16+20=36>0
D>0 means there are two real roots
(c) D = 20^2-4*4*25 = 0
D=0 means there is one real root with multiplicity 2
