Calculate 4u 6w and state the answer in two forms a as a li

Calculate 4u - 6w and state the answer in two forms, (a) as a linear combination of i and j and (b) in component form. u = 5i + j and w = i-8j State your answer as a linear combination of i and j. 4u-6w= i+ j State your answer in component form. 4u-6w=lang, rang

u=5i+j , w=i -8j

4u -6w = 4(5i+j) -6(i-8j)= 20i + 4j -6i +48 j
