U = { u1= (5,2;5) ; u2=( 2,1,3) ; u3=( 3,1,3) } V = { v1=(6,2,1) ; v2=( 7,2,1) ; v3=(-1,7,4) }
Chứng tỏ U V là cơ sở của R3

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

The answer is idk yo

The answe maybbe
