Determine whether b can be written as a linear combination of a, and a2. In other words, determine whether weights X₁ and x₂ exist, such that x₁a₁ + x₂a2 = b. Determine the weights x₁ and x2 if possible. Let a₁ = 1 3 -6 a₂ = <-4 1 1 O A. x₁ = 3, x₂ = -5 OB. x₁ = 2, x₂ = -3 OC. x₁ = 2, x₂ = -4 OD. There is no solution. and b= 18 2 - 16

If P = (1, 1) and Q = (-4, –4), find the components of PQ PQ =

If a = (2.-1.9) and b (, 2.1). find the following. a x b = %3D b x a = %3D

p = the number of people in line ahead of Trudy and Mariaw = the length of time Trudy and Maria will need to wait Which of the variables is independent and which is dependent?
