The formula R = 0.075t + 3.85 can be used to predict the world record in the 1500 meter run, t years after 1930.
\n" ); document.write( " Determine an inequality that identifies the years in which the world record will be less than 3.7 minutes.
\n" ); document.write( "Solve for t
\n" ); document.write( ":
\n" ); document.write( "The way this is written makes no sense. R = -0.075t + 3.85 would makes some sense
\n" ); document.write( "From this we can surmise:
\n" ); document.write( "1 yr after 1930: R = 3.85 - .075 = 3.775 min which is what you would expect
\n" ); document.write( ":
\n" ); document.write( "Using that
\n" ); document.write( "-0.075t + 3.85 < 3.7
\n" ); document.write( ":
\n" ); document.write( "Subtract 3.85 from both sides
\n" ); document.write( "-0.075t < 3.7 - 3.85
\n" ); document.write( ":
\n" ); document.write( "-0.075t < -.15
\n" ); document.write( "t has to be positive, Multiply both sides by -1, this reverses the inequality sign
\n" ); document.write( "0.075t > .15
\n" ); document.write( "t > \".15%2F.075\"
\n" ); document.write( "t > 2 yrs, More than two years after 1930 (1932) the record would be < 3.7 min
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Did this make sense to you now? \n" ); document.write( "
\n" );
