Question

HELP PLEASE!!!! QUICK AND CORRECT ANSWERS WILL GET MEDAL AND FAN!!!!!

Answer 1

You may use counter examples and eliminate options

Answer 2

i think the answer is b

Answer 3

For example if you let \(j=1\) and \(k=-1\) then\[(j,j)=(1,1) \]\[(k,k)=(-1,-1)\]and these are not in the same quadrant

Answer 4

For 'b' what if I say let \(j=-1\) and \(k=-1\)

Answer 5

ohhhh

Answer 6

(-1,-1 )

Answer 7

and

Answer 8

umm

Answer 9

idk

Answer 10

... sorry...

Answer 11

there is nothing to be sorry about

Answer 12

\((jk,jk)=(1,1)\) because \((-1)(-1)=1\) so also 'b' cannot be the answer

Answer 13

right?

Answer 14

because when you add 2 negatives it equals a a positive

Answer 15

emm.. when you multiply two negatives actually ;)

Answer 16

ohh right

Answer 17

so here is the point, If we want two points be lie in the same quadrant their x's must have the same sign and their y's must have the same sign

see for example (2, -4) and (13, -35) lie in the same quadrant (4th quadrant)

Answer 18

What do you think about two other options?

Answer 19

so its either c or d

Answer 20

umm

Answer 21

i think the answer would be c

Answer 22

and remember that if you multiply a number by a positive number its sign doesn't change

Answer 23

ok so i think its d

Answer 24

very good, answer is 'd'

Answer 25

Can you tell me a counter example for 'c'?

Answer 26

no.. math is not my strong point

Answer 27

ok, no problem :)

Answer 28

so just to double check the answer is d
