Question 177847: please grahph these
[>] means equal or greater than..
() means ablsoule value.. thanks for helping


y>x-5
3x+y[<]-2

y[<]x+2
y>(x-3)+1

You can put this solution on YOUR website!
please graph these
[>] means equal or greater than..
() means absolute value.. thanks for helping
-------------------
Note: You cannot DIRECTLY graph an inequality. You need to
first graph the EQUALITY that forms its boundary.
-------------------
y>= x-5
1st: Graph the line y = x-5 as a dashed line
2nd: Shade the halfplane Above the line because you want the "greater than".

---------------------------------------
3x+y[<]-2
3x + y <= -2
y <= -3x -2
1st: Graph the line y = -3x -2 as a solid line
2nd: Shade the halfplane below the boundary line because you want "less than".
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C-3x-2%29
----------------------------------------
y[<]x+2
y <= x + 2
1st: Graph the line y = x + 2 as a solid line.
2nd: Shade the halfplane below the boundary line.
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cx%2B2%29
----------------------------------------
y>(x-3)+1
y > |x-3| + 1
1st: Graph the |x-3|+1 as a dashed line.
2nd: Graph the sector above the boundary.
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cabs%28x-3%29%2B1%29
==================================================
Note: This site cannot accept the shading I described.
