Algebra.Com's Answer #168059 by drj(1380)![]() ![]() You can put this solution on YOUR website! Solve the system of equations by graphing. Then classify\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "6x + y = 46 \n" ); document.write( "7x + 8y = 40\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 1. Graph the two lines from above as shown below\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 2. Based on the graph the intersection point is (8,-2) or x=8 and y=-2.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 3. Check if the solution (8,2) satisfies the above linear system of equations\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "6x + y = 46 or 6*8+-2=46 or 46=46 which is a true statement \n" ); document.write( "7x + 8y = 40 or 7*8+8*(-2)=40 or 40=40 which is another true statement\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 4. ANSWER: The solution is (8,2). The equations are independent and consistent providing a unique solution.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "I hope the above explanation was useful.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "And good luck in your studies!\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For free Step-By-Step Videos on Introduction to Algebra, please visit \r \n" ); document.write( "\n" ); document.write( "http://www.FreedomUniversity.TV/courses/IntroAlgebra or for Trigonometry visit \r \n" ); document.write( "\n" ); document.write( "http://www.FreedomUniversity.TV/courses/Trigonometry.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Respectfully, \n" ); document.write( "Dr J\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
