Algebra.Com's Answer #40815 by praseena(37) ![]() You can put this solution on YOUR website! you can solve this problem numerically like this,\r \n" ); document.write( "\n" ); document.write( "y=2x+1 \n" ); document.write( "when x=7, substitute the x value=7 in the given rule. \n" ); document.write( " y=2*7+1 \n" ); document.write( " =14+1 \n" ); document.write( " =15 \n" ); document.write( "That is when the input is 7, the output is 15.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "To predict the output when input is 31/2, \n" ); document.write( "for that, you just put the value x=31/2 in the given rule \n" ); document.write( "that is, y = 2 * 31/2 +1 \n" ); document.write( " = 31 + 1= 32 \n" ); document.write( "That is when the inputis 31/2, the out put is 32\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
