Algebra.Com's Answer #563059 by Techpriest(29)![]() ![]() ![]() You can put this solution on YOUR website! In order to find the small number and large number, we must express it as an algebraic expression.\r \n" ); document.write( "\n" ); document.write( "One positive number is 6 more than twice another of a number can be expressed as: \n" ); document.write( " \n" ); document.write( "If their product is 308: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Through the expression shown above we can substitute y from the first equation to the second equation.\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( " \n" ); document.write( " \n" ); document.write( "So, x = 11 or -14. \n" ); document.write( "In order to find y, we substitute the x-value in the first equation for ALL solutions. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "AND \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So, y = 28 or -22. \n" ); document.write( "So, a solution of {11,28} or {-14,-22} can be plotted on a graph. \n" ); document.write( "HOWEVER, the problem tells you that y is a positive number. \n" ); document.write( "Since {11, 28} is positive. The small number assuming that it is x will be 11 and the large number assuming that it is y will be 28. \n" ); document.write( " |
