Algebra.Com's Answer #645674 by Theo(13342)![]() ![]() You can put this solution on YOUR website! your equation is 13 - (2c+2) >= 2(c+2) + 3c\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "i think you have to solve it first.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you will get c <= 1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "in interval notation that would be c = (- infinity, 1]\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "that means that minus infinity is smaller than c which is smaller than or equal to 1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the symbol ( on the left means c is greater than minus infinity.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the symbol ] on the right means that c is less than or equal to 1.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "here's some references.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the first is on interval notation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "http://www.coolmath.com/algebra/07-solving-inequalities/03-interval-notation-01\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the second is on set builder notation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "http://www.coolmath.com/algebra/07-solving-inequalities/02-set-builder-notation-01\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "in set builder notation, your answer would look like this:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "{ c | c <= 1 }\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "this means the set of all c's such that c <= 1 \n" ); document.write( " |
