Which of the following planes are parallel? Are any of them identical?
P1: 4x - 2y - 6z = 3
P2: 4x - 2y - 2z = 6
P3: -6x + 3y -9z = 5
P4: z = 2x - y - 3
please explain each step in detail
a) Planes P1 & P2 Intersect. If you subtract P1 from P2 you will get 4z = 9. This means they have a point of intersection at Z = 2.25 and hence not ...
