X2 + y2 = 13
x2 - y2 = 5
check all of the following that are solutions to the system shown.

a. (3, 2)
b. (3, -2)
c. (-3, 2)
d. (-3, -2)

(3,2),(3,-2),(-3,2),(-3,-2)

Step-by-step explanation:

The given system of equations is

Add equations (i) and (ii) is

Solve the equation for x. For this divide both sides by 2

Take square root both sides

For x = 3, -3

Therefore, the solutions are

(3,2),(3,-2),(-3,2),(-3,-2)

Therefore, all the points are the solutions of the system of equations.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
