Algebra.Com's Answer #837725 by mananth(16946)![]() ![]() You can put this solution on YOUR website! From day 1 to day 6, Tim did 10 lunges on the first day and added 4 more lunges each day. So, on day x \r \n" ); document.write( "\n" ); document.write( "y = 4(x-1) + 10\r \n" ); document.write( "\n" ); document.write( "Simplifying this equation, we get:\r \n" ); document.write( "\n" ); document.write( "y = 4x + 6\r \n" ); document.write( "\n" ); document.write( "day 7, y would be 0.\r \n" ); document.write( "\n" ); document.write( " the equation for the number of lunges Tim did for 7 days will be\r \n" ); document.write( "\n" ); document.write( "y = 4x + 6(x-1)(x<7) + 0 (Day 7 0)\r \n" ); document.write( "\n" ); document.write( "Simplify\r \n" ); document.write( "\n" ); document.write( "y = 4x - 18 (x<7) \n" ); document.write( "y = 4x(x-7) - 18 \n" ); document.write( " |
