Find the common ratio for the following sequence. 27, 9, 3, 1, ... = 1/3 Find the common ratio for the following sequence. 1/2, -1/4, 1/8, -1/16, ... = -1/2 Find the common ratio for the following sequence. 1/2, -1/4, 1/8, -1/16, ...
= -1/2
The lines y = 2x - 1 and y = -2x + 3 intersect at exactly one point which means this system has exactly one solution. so the system is consistent and independent
