Algebra.Com's Answer #653205 by Othel(27)![]() ![]() ![]() You can put this solution on YOUR website! We are told that X is inversely proportional to the square of Y. So... \n" ); document.write( " \n" ); document.write( "Let us use the first of the two options. \n" ); document.write( "If x=8, then \n" ); document.write( "And... \n" ); document.write( " \n" ); document.write( "Now we will raise our value of Y by 200%... \n" ); document.write( " \n" ); document.write( "Now just a little algebra... \n" ); document.write( " \n" ); document.write( "Then.. \n" ); document.write( " \n" ); document.write( "After raising Y by 200%, the value of X is... \n" ); document.write( " \n" ); document.write( "And comparing this to our first value of x, we find that when X=8, and then Y is raised by 200%, X is DECREASED by Approximately 82.3 %. \n" ); document.write( " \n" ); document.write( "Check your answer! \n" ); document.write( "I hope this helps!
