- Solve for X in the Equation, given A=-401-532 and B=12-2144 a 3X+2A=B b 2A5B=3X c X-3A+2B=0 d 6X4A-3B=0arrow_forwardFind the answer to the following subtraction problems by using vectors on the number line in conjunction with the missing addend approach. Draw an arrow from the subtrahend to the minuend as shown in the examples on pages 28&29. Before drawing the missing addend representing the answer to the problem, label and mark your number line with at least 0 and one point on each side of zero. Then, draw the vector that represents the answer to each problem and label the vector with that number. Then take a picture of your work and upload it. 3 −- 7 -1 −- 4 9 −- -6 -2 −- -5 8 −- -8 4 −- 4arrow_forwardDetermine which of the following vectors are orthogonal to each other: 12 2 X = -5 3 X2 = |1 X3 = |-3 3arrow_forward

- This is a linear algebra problem from section 1.3 "Homogenous Equations". All step work is greaty appreciated!arrow_forwardPlease solvearrow_forwardLet A = - - 3 [1] [2] and b = 3 9 b2 Show that the equation Ax = b does not have a solution for some choices of b, and describe the set of all b for which Ax=b does have a solution. How can it be shown that the equation Ax=b does not have a solution for some choices of b? A. Find a vector x for which Ax=b is the identity vector. B. Row reduce the augmented matrix [ A b] to demonstrate that A b has a pivot position in every row. C. Find a vector b for which the solution to Ax=b is the identity vector. D. Row reduce the matrix A to demonstrate that A does not have a pivot position in every row. E. Row reduce the matrix A to demonstrate that A has a pivot position in every row.arrow_forward
