How many real solutions does this system of equations have? x2+y2=363x−y+1=0 A. 0 B. 3 C. 2 D. 1

Correct option: C -> 2

Step-by-step explanation:

The first equation is:

And the second equation is:

From the second equation, we have:

Using this value of y in the first equation, we have:

Calculating the discriminant Delta, we have:

We have , so we have two real values for x, therefore we have two solutions for this system.

Correct option: C.

(If the system of equation is actually:

We would have:

We also have , so we have two solutions for this system.

Correct option: C.)

the correct answer is 5 6 and 7

open side up . . 1/50 . . 2%

closed side up . . 5/50 . . 10%
