Algebra.Com's Answer #117374 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! 45,000 means that y = 45, since y = 1,000's of cars. \n" ); document.write( "45 = 4x+5 Subtract 5 from both sides. \n" ); document.write( "40 = 4x Divide both sides by 4. \n" ); document.write( "x = 10 Now add 10 to 1996 to get 2006. \n" ); document.write( "So, in 2006 45,000 cars will be sold, then in 2007 the number of cars sold will exceed 45,000, so the answer is 2007 and later. \n" ); document.write( " \n" ); document.write( " |
