Question

Find the values of the variables.

[-12, -w^2, 2f, 3] = [2k, -81, -14, 3]

Answer 1

@jim_thompson5910 im sorry i keep bugging haha. but this one's bugging me

Answer 2

use this:
if (x,y)=(a,b)
then x=a and y=b.

Answer 3

freckles has the right idea

Answer 4

just equate corresponding components

Answer 5

Thank you (:

Answer 6

-12 = 2k ----> k = ???

etc etc

Answer 7

@freckles would -12 = 2k , k=-6?

Answer 8

correct

Answer 9

YES. Okay so now, the next step would be -w^2 = -81?

Answer 10

good

Answer 11

would it be 0.012 or 0.0123?

Answer 12

-w^2 = -81. Multiply by -1:
w^2 = 81
w = sqrt(81) = 9

Answer 13

i was waay off, thank you!

Answer 14

you are welcome.

Answer 15

and what about 2f = -14. ??

Answer 16

keep in mind that if w^2 = 81, then w = 9 or w =-9

since those two values make w^2 = 81 true

Answer 17

try to undo that multiplication of 2 by dividing both sides by ?

Answer 18

right, thanks for that. i fixed it @jim_thompson5910

divide both sides by -14?
