Asked by Alice
Is this correct if not could you explain how to make it correct?
find (a)2v+u, (b)u-3v), and (c)5u-v.
u=i-j v=6i+9i
a. 2v+u
u=i-j, v=6i+9i
=(12i+18j) + (i-j)
=13i+ 17j
b. u-3v
(i-j)-(18i+27i)
-17i - -26j
c. 5u-v
(5i-5j)-(30i+54j)
-25i - -59j

a) ok
b) (i-j)-(18i+27i)
= -17i - 28j
c)
(5i-5j)-(30i+54j) --> you did 5u - 5v instead of 5u-v
b) (i-j)-(18i+27i)
= -17i - 28j
c)
(5i-5j)-(30i+54j) --> you did 5u - 5v instead of 5u-v
