Algebra.Com's Answer #813099 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! p=ks where k is the constant of proportionality. P is directly proportional to s. This problem. \n" ); document.write( "p=k/s, P is inversely proportional to s, so if s rises P falls.\r \n" ); document.write( "\n" ); document.write( "What models this relationship is p=2s \n" ); document.write( "numbers 2 and 4 don't work, and while p is equal to s+3, that is not proportional, for 2s should equal 12 in the problem above, but 2s+3 would be 9. \n" ); document.write( " |
