Answer:

Option C.

Step-by-step explanation:

System of the equation consists of two equations

2x + y - 4 = 0

2x + y - 4 + 4 = 0 + 4

2x + y = 4--------(1)

and 2x - y - 4 = 0

2x - y + 4 - 4 = 0 + 4

2x - y = 4------(2)

Now we will add these equations to eliminate y.

(2x + y) + (2x - y) = (4 + 4)

(2x + 2x) + (y - y) = 8

4x = 8

Therefore, resulting equation will be 4x = 8

Option C. will be the answer.

4x=8
This is because when you add the two expression together 2x+2x=4x the y values cancel and -4+-4=-8
4x-8=0 is equivalent to 4x=8

svetlana [45]

Answer:

The discriminant D=0

Step-by-step explanation:

For the duadratic polynomial ax^2+bx+c the discriminant is

D=b^2-4ac.

In your case, for the polynomial 4x^2-20x+25,

  • a=4;
  • b=-20;
  • c=25;
  • D=(-20)^2-4\cdot 4\cdot 25=400-400=0.
