Question 146870
1.{{{-y<=36}}}
{{{y>=-36}}}
Remember when you multiply an inequality by negative number, -1, in this case, the signs flips (greater than becomes less than and vice versa).
Let check the answer. 
We'll pick y=0, since 0>-36.
{{{-y<=36}}}
{{{0<=36}}}
True, good answer.
2. {{{5/14>=-2e/7}}} 
{{{(5/14)(-7/2)<=e}}}Multiply both sides by (-7/2), signs flip.
{{{e>=-5/4}}}
Let check the answer. 
We'll pick e=0,since 0>-5/4.
{{{5/14>=-2e/7}}} 
{{{5/14>=0}}}
True, good answer.
