Determine if the following system of equations is independent, dependent, or inconsistent: \n" ); document.write( "–7x – 5y = –4 \n" ); document.write( "–35x – 25y = 13 \n" ); document.write( "If you multiply thru the 1st equation by 5 you get: \n" ); document.write( "-35x -25y = -20 \n" ); document.write( "---------------- \n" ); document.write( "Do you see how \"inconsistent\" that is with the 2nd equation?? \n" ); document.write( "How could the same expression equal 13 and also equal -20 ?? \n" ); document.write( "The system is inconsistent. \n" ); document.write( "A) Independent \n" ); document.write( "B) Dependent \n" ); document.write( "C) Inconsistent \n" ); document.write( "----------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
