Answer 2

Step-by-step explanation:

the question means to say that which values of x and y when put together result in the same answer

so first equation y= -x²+2x+4

and second y=4-x ( rewrite the equation making x the subject)

so when u choose B

when x is 0 y is 4 ( check by putting in value of x)

and when x is 3 y is 1

this satisfies equation for both equations so B is correct
