Algebra.Com's Answer #719928 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! a) 6n^-2 <4n^-1; this is 6/n^2 < 4/n. The one on the left is always positive, the one on the right always negative, so it can't be this.\r \n" ); document.write( "\n" ); document.write( "b) n/4 > -6n^-1. n/4 > - (6/n). The one on the left is always negative, the one on the right is always positive., so it can't be this.\r \n" ); document.write( "\n" ); document.write( "c) 6n^-1 < 4n^-1 6/n <4/n. Since n is negative, that is like saying 6 >4, and that is true. ANSWER.\r \n" ); document.write( "\n" ); document.write( "d) 4n^-1 > (6n)^-1 4/n > 1/(6n). This would be the same as 4 < (1/6), and that is not true. \n" ); document.write( " |
