Write the vector u as a sum of two orthogonal vectors one of which is the vector projection of u onto v, projvu u=(-9,3), v=(-9,-3).

a. (-7.2,-2.4)+(-1.8,5.4)

b. (-6,-2)+(-3,9)

c. (-9,-3)+(0,6)

d. (3,1)+(-12,2)

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

answer: there are a lot of coordinates some are (3,0) or (0,1)
