(please help)How many real solutions exist for this system of equations? y = x2 + 4 y = 4x A.

zero

B.

one

C.

two

D.

infinite

B

Step-by-step explanation:

y=x^(2)+4

y=4x

lets solve by substitution

4x=x^2+4

0=x^2-4x+4

0=(x-2)(x-2)

x=2 or x=2

y=4x

y=4*2

y=8

same for the other answer

(2,8)

this system has only one solution: (2,8)

Thus, the correct answer is B (one solution)

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
