Question

vector help!!! PLZ

Answer 1

suppose u = 3i - 4j, v= 4i -3j and w = i + j

represent 1/2(u+v) - 1/4w in standard form

Answer 2

coeff of i add together and the same for coeff of j

Answer 3

can you repeat that sorry

Answer 4

i keep getting 27/4 i and -29/4j and that is not correct

Answer 5

i get 13/4 for i

Answer 6

ok let me see your adding your i's and j's and plugging them into the equation? what do you plug in for w

Answer 7

3/2 + 4/2 - 1/4

Answer 8

how did you get that?!?!?!

Answer 9

1/2 (3i - 4j) +1/2 (4i -3j) -1/4 (i + j)

Answer 10

ok

Answer 11

clear?

Answer 12

im not sure yet...

Answer 13

jus separate coefficients of i and j from what i wrote
