Question

Help me! Medal will be given!

What are the solution(s) to the following system of equations?
y = x2
y = –x

Anwser:
(–1, 1) and (1, 1)

(0, 0)

(0, 0) and (–1, 0)

(0, 0) and (–1, 1)

Answer 1

Just plug the points in

Answer 2

I'm still confused...

Answer 3

(-1,1) and (1,1)

y = x2 1=(-1)^2 true
y = –x 1=-(-1) true

y = x2 1=(1)^2 true
y = –x 1 = -1 false first set doesn't work

Answer 4

Refer to the Mathematica attachment.

Answer 5

(0,0)
y = x2 0 = 0^2 true
y = –x 0 = -0 true

Answer 6

(0, 0) and (–1, 0)
y = x2 0 = 0^2 true
y = –x 0 = -0 true

y = x2 0 = -1^2 false this set doesn't work
y = –x

Answer 7

So it would be (0,0). Right?

Answer 8

From Oliveeeuuuh attachment...look where the lines intersect. That represents your solution

Answer 9

heyyyyyyy

Answer 10

(0,0) is only one of the solutions.
