Solve and answer in interval notation:
\n" ); document.write( "-3x - 12 < -9 and 2(x+7) ≥ -50
\n" ); document.write( "**
\n" ); document.write( "-3x - 12 < -9
\n" ); document.write( "-3x<-9+12
\n" ); document.write( "-3x<3
\n" ); document.write( "Divide both sides by -3 and reverse inequality sign
\n" ); document.write( "x>-1
\n" ); document.write( "..
\n" ); document.write( "2(x+7) ≥ -50
\n" ); document.write( "2x+14≥-50
\n" ); document.write( "2x≥-50-14
\n" ); document.write( "2x≥-64
\n" ); document.write( "x≥-32
\n" ); document.write( "..
\n" ); document.write( "ans
\n" ); document.write( "(-1, ∞) (since this is a \"and\" inequality, functions must intersect or overlap) \n" ); document.write( "
\n" );
