Answer 4

go to desmos

Answer 5

ok

Answer 6

type desmos.com

Answer 7

graph it, and ull see

Answer 8

"by hand, find the solution set for the following system"???

Answer 9

oh. try subtracting the two equations

Answer 10

ok so thats 4.

Answer 11

u get 0=4, which is incorrect, so there is no answer

Answer 12

OHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHhh

Answer 13

can u help me

Answer 14

i can try. :o

Answer 15

question above urs

Answer 16

@Plasmataco it says on my study guide that the answer is +-sqrt5 and -+2

Answer 17

what if i told u it was wrong?

Answer 18

yes

Answer 19

it should be undefined

Answer 20

these are two concentric circles.

Answer 21

right, i see that. but how do i come about the answer?

Answer 30

okay so how do i go about getting the answer

Answer 31

already you have shown the work.
it is good.

Answer 32

\[\left( -\sqrt{5} \right)^2=5,~and~\left( \sqrt{5} \right)^2=5\]

Answer 33

how did you get that from the equations????
