Algebra.Com's Answer #279283 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! If y = 0 (mod 2) then y + 1 = 0 + 1 = 1 (mod 2), \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4y = 4(0) = 0 (mod 2)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4y + 1 = 4(0) + 1 = 1 (mod 2)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(d) makes no sense, it is already not an integer. Since (b) is the only integer 0 mod 2, it is the only number divisible by 2 and therefore, the only even integer. \n" ); document.write( " |
