Question

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

Answer 1

Answer:

The graph in the attached figure

Step-by-step 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

The graph in the attached figure
