Consider the linear system a1x + b1y + c1z = d1 a2x + b2y + c2z = d2 a3x + b3y + c3z = d3 of three equations in three unknowns to represent three planes p1, p2, and p3 in xyz-space. describe the solution set of the system in each of the following cases. a) the three planes are parallel and distinct b) the three planes coincide (p1=p2=p3) c) p1 and p2 coincide and are parallel to p3 d) p1 and p2 intersect in a line l that is parallel to p3 e) p1 and p2 intersect in a line l that lies in p3 f) p1 and p2 intersect in a line l that intersects p3 in a single point.

i think it might be a but you might want a second opinion

step-by-step explanation: the first one means to spread the product throughout the marketplace such that a large number of people can buy it.  

the second means the process of making a product or service available for the consumer or business user that needs it.

mark this brainliest and i will be glad to .

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
