Question 184415
</pre><font size=4><b>
{{{x+2y<=3}}}, EQN 1
{{{x+2y<=4}}}, EQN 2
In EQN 1, we get
{{{2y<=3-x}}}----->{{{cross(2)y/cross(2)=(3-x)/2}}}
{{{y=(3/2)-(1/2)x}}}, EQN 1.1
We see the graph:
{{{drawing(300,300,-6,6,-6,6,graph(300,300,-6,6,-6,6,(3/2)-(1/2)x),green(line(0,1.5,0,6)),green(line(0,1.5,3,0)),green(line(3,0,6,0)))}}}
*NOTE: Values of (x,y) SHOULD TOUCH THE GREEN LINE (or ABOVE or RIGH)to satisfy the equation.
.
Also in EQN 2:
{{{2y<=4-x}}}-----> {{{cross(2)y/cross(2)=(4-x)/2}}}
{{{y=(4/2)-(1/2)x}}}
{{{y=2-(1/2)x}}}, EQN 2.2
We see the graph:
{{{drawing(300,300,-6,6,-6,6,graph(300,300,-6,6,-6,6,2-(1/2)x),green(line(0,2,0,6)),green(line(0,2,4,0)),green(line(4,0,6,0)))}}} *NOTE: Values of (x,y) SHOULD TOUCH THE GREEN LINE (OR ABOVE OR RIGHT) to satisfy the equation.
Thank you,
