Algebra.Com's Answer #714861 by Theo(13342)![]() ![]() You can put this solution on YOUR website! to prove the statements false, all you have to do is find an example where the statements are not true.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "i started with a > b + c and assumed a was 10. \n" ); document.write( "then b + c had to be smaller than 10. \n" ); document.write( "i assigned 5 to b and 4 to c. \n" ); document.write( "a = 10 \n" ); document.write( "b = 5 \n" ); document.write( "c = 4 \n" ); document.write( "a > b + c becomes 10 > 5 + 4 which becomes 10 > 9 which it true.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "i then started with d > b + a. \n" ); document.write( "b = 5 and a = 10 from the previous inequality. \n" ); document.write( "this became d > 5 + 10 which meant that d > 15. \n" ); document.write( "i chose d = 16.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "i now have: \n" ); document.write( "a = 10 \n" ); document.write( "b = 5 \n" ); document.write( "c = 4 \n" ); document.write( "d = 16\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "then i went through the selections.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "A. a>d not true because 10 not greater than 16 \n" ); document.write( "B. b>a+d not true because 5 not greater than 26 \n" ); document.write( "C. c>a-b not true because 4 not greater than 5 \n" ); document.write( "D. d>c true because 16 > 4\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
