'Intersection of Two Planes' lesson under vectors. Please help me. I have posted answers too. I don't know how they got it tho.
a. -' m A system of two equations in three unknowns has been manipulated, and, after correctly using elementary operations, a student arrives at the following equivalent system of equations: xy+z=1 x+y+z=3 1ln'll'hat does this equivalent system mean? A system of two equations in three unknowns has been manipulated, and, after correctly using elementary operations, a student arrives at the following equivalent system of equations: 2xy+22=1 x+y+z= 1F.I"1.I']1at does this equivalent system mean? A system of two equations in three unknowns has been manipulated, and, after correctly using elementary operations, a student arrives at the following equivalent system of equations: xy+z=1 x+y+22=4 1ln'll'hat does this equivalent system mean? 1. a. The two equations represent planes that are parallel and not coincident. b. Answers may vary. For example: x-y+z=l,x-y+z=-2 2. a. X= + s - Ly = S, Z = 1; 2 s, fER; the two planes are coincident. b. Answers may vary. For example: x-ytz=-1, 2x - 2y + 2z = -2 3. a. x = 1 + s,y = s,z= -2, sER; the two planes intersect in a line
