Question

Find -6W - 3(2u - v) if u = i + 2j, v = -3j, and w=combination of unit vectors.:-). Express your answer as a linear

Answer 1

ok

u = i + 2j

v = -3j

w = -1/3i - 7/3j

$\begin{gathered} \text{ -6(}\frac{-1}{3}i\text{ - }\frac{7}{3}j)\text{ - 3(2(i + 2j)- (-3j))} \\ \frac{6}{3}i\text{ + }\frac{42}{3}j\text{ - 6i - 6j + 3j} \\ 2i\text{ + 14j - 6i - 6j + 3j} \\ -4i\text{ + 11j} \end{gathered}$

Result - 4i + 11j
