Algebra.Com's Answer #450565 by Susan-math(40)![]() ![]() ![]() You can put this solution on YOUR website! 2x-3y=-6 gives \n" ); document.write( "\n" ); document.write( "so }}}x^2+y^2=25}}} becomes \n" ); document.write( "\n" ); document.write( "so \n" ); document.write( "\n" ); document.write( "and \n" ); document.write( "\n" ); document.write( "Using the quadratic formula with a=13/4, b=-9 c=-16\r \n" ); document.write( "\n" ); document.write( "Then (((y=(9 +-sqrt(81-4(13/4)(-16)))/2(13/4)=(9+-sqrt(289))/(13/2)=(9+-17)/(13/2)}}} which gives y=4 or y=-16/13\r \n" ); document.write( "\n" ); document.write( "substitute those into the linear equation to find x. \n" ); document.write( "y=4 gives \n" ); document.write( "y=-16/13 gives |
