Question

Find the variables

[-12 -w2] [2k - 81]
[2f 3] = [-14 3]

Answer 1

the ones in \(\color{red}{red}\)
\[[-12 -\color{red}w^2] [2\color{red}k - 81] \]

Answer 2

Can you help walk me through this?

Answer 3

i can't really understand what it says, or what it is asking for

Answer 4

what are the brackets for?

Answer 5

Its a matrix. [-12 -w2] [2k - 81]
[2f 3] [-14 3]
Theyre equal to eachother

Answer 6

ooooh i see!

Answer 7

set each in one matrix equal to the corresponding entry in the other matrix
for example
\[-12=2k\]

Answer 8

that makes \(k=-6\)

Answer 9

clear?

Answer 10

Yes

Answer 11

ok you have to do it four times, (3 since i did the first one)
that is all

Answer 12

k= -6 w=40.5 and f=-7?

Answer 13

i think \(w\) is wrong

Answer 14

\[-w^2=-81\iff w=9, w=-9\]
