Given the vectors m==(-2, 3) and n=(-8, 9), find 7m and m+n.Write your answers in component form.7m =Х6?m + n =

Sagot :

Answer:

7m= (-14, 21) and m+n = (-10, 12)

Explanation:

Given the following vectors

m =(-2, 3) and n=(-8, 9)

7m = 7(-2, 3)

7m = [7(-2), 7(3)]

7m = (-14, 21)

m+n = (-2, 3) + (-8, 9)

m+n = (-2-8, 3+9)

m+n = (-10, 12)

Hence the vector form of 7m and m+n are (-14, 21) and (-10, 12) respectively
