Algebra.Com's Answer #827474 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Graphically determine the solution to the systems\r \n" ); document.write( "\n" ); document.write( "1. y=2x^2-12x+19,y=2x-1 \n" ); document.write( "---- \n" ); document.write( "For the parabola y = 2x^2-12x+19, pick values for x and find y. \n" ); document.write( "Plot the points and draw the curve thru them. \n" ); document.write( "y = 2x-1 is a straight line, so 2 points are needed \n" ); document.write( "The intersections are the solutions. \n" ); document.write( "================ \n" ); document.write( "There are several FREE graph softwares online. \n" ); document.write( "I use www.padowan.dk \n" ); document.write( "================= \n" ); document.write( "2. y=x^2-2x+8,y=x-7 \n" ); document.write( "Same as #1 \n" ); document.write( "--------------- \n" ); document.write( "3. y=x^2+5x-7, y=2x^2=2x+3 \n" ); document.write( "If you meant x^2+5x-7, y=2x^2-2x+3 it's 2 parabolas. \n" ); document.write( " \n" ); document.write( " |
