If y is inversely proportional to the cube of x, what percent does y change if x decreases by by 25%?
\n" ); document.write( "
\"matrix%281%2C3%2C+y%2C+%22=%22%2C+k%2Fx%5E3%29\" ----- y inversely proportional to cube of x\r\n" );
document.write( "\"matrix%281%2C3%2C+y%5B2%5D%2C+%22=%22%2C+k%2F%28.75%5E3x%29%29\" ----- Substituting .75 for x, since after a 25% reduction, 75% (.75) remains \r\n" );
document.write( "\r\n" );
document.write( "Comparing y and y2, we see a CHANGE from \"matrix%281%2C3%2C+1%2F1%2C+to%2C+1%2F.75%5E3%29\"\r\n" );
document.write( "Therefore, change in y after 25% reduction in x =
