Mathematics

B. (0,-4) and (2,0)

Step-by-step explanation:

The given system of equations is:

y=2x-4

y=x^2-4

Equate both equations and solve for x.

x^2-4=2x-4

x^2-4-2x+4=0

x^2-2x=0

Factor;

x(x-2)=0

x=0,x-2=0

x=0,x=2

When x=0, y=2(0)-4=-4

Hence (0,-4) is one solution

When x=2, y=2(2)-4=0

Hence (2,0) is another solution

The correct choice is B.
