Question

What are all of the ordered pair solutions for the system of equations shown below?

Answer 1

we know that; 3y^2=187-7x^2
and 3y^2-7x=47
187-7x^2-7x=47
can you continue??

Answer 2

i have no idea how to continue :( ha

Answer 3

why not just graph them and find those points of intersections

Answer 4

140-7x^2-7x=0
20-x^2-x=0
what are the values of x??

Answer 5

or better yet just sub your values and find out which ones are true in all equations

Answer 6

x=-5,4

Answer 7

what comes after that? @marsss

Answer 8

@precal i'll try that afterwards, thanks :)

Answer 9

right now you should plug those and find the values of y. ok??

Answer 10

one minute

Answer 11

when x=4 y=5,-5

Answer 12

when x=-5 y=2,-2

Answer 13

ok, you found :) answer is second one.

Answer 14

so which choice would that be in the multiple choice?

Answer 15

i said, second one.

Answer 16

ohhh i thought you meant the second equation i'm sorry

Answer 17

thanks so much :)
i have just one more problem i need help with, nobody could seem to figure it out ill post now

Answer 18

ok. sure.
