Question

Which of the following graphs represents the solution(s) of the following system x^2+y=7 x^2+y^2=49​

UPDATE : its B

Answer 1

they're right, its b

Explanation:

Answer 2

The graph in the attached figure

Explanation:

we have

`x^(2) +y=7`

`y=-x^(2)+7` ----> equation A

This is the equation of a vertical parabola open downward

The vertex is the point (0,7)

`x^(2) +y^(2)=49`

`x^(2) +y^(2)=7^(2)` ----> equation B

This is the equation of a circle with center at (0,0) and radius equal to 7 units

The y-intercepts of the circle are the points (0,7) and (0,-7)

therefore
