Q1. Find the equation of a circle whose diameter has end points (4,-1) and (-6,7).
\n" ); document.write( "-----------
\n" ); document.write( "Find the midpoint, that's the center.
\n" ); document.write( "The distance from the midpoint to either given point is the radius.
\n" ); document.write( "---
\n" ); document.write( " $\"%28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2\"$ is a circle with the center at (h,k) radius r
\n" ); document.write( "===================
\n" ); document.write( "Q2. Solve the inequality |5x+11|>7 and write the solution set in interval form.
\n" ); document.write( "|5x+11|>7
\n" ); document.write( "--------
\n" ); document.write( "5x+11 > 7
\n" ); document.write( "5x > -4
\n" ); document.write( "x > -4/5
\n" ); document.write( "==========
\n" ); document.write( "-(5x+11) > 7
\n" ); document.write( "5x+11 < -7
\n" ); document.write( "5x < -18
\n" ); document.write( "x < -18/5 \n" ); document.write( "

\n" );
