 Linear-equations/520429: Please help me graph the inequality in a coordinate plane for the two items below. 1) 10x is > or equal to 10/3 2) y> -4 -x 1 solutions Answer 346050 by solver91311(20879)   on 2011-10-24 19:03:01 (Show Source): You can put this solution on YOUR website! Step 1: Change the relationship symbol to "=". Graph the resulting line. If the original relationship symbol was or , do it with a dashed or broken line. If your symbol was or , graph the equation with a solid line. Step 2: Pick any point on the coordinate plane that does not lie on the line you just graphed. If the line does not pass through the origin, then the origin is an excellent choice for this step. If the line does pass through the origin, select a point other than the origin -- I recommend a point that has small integer coordinates. Step 3: Substitute the values of the coordinates of the point chosen in Step 2 for the corresponding variables in the inequality you started with in Step 1. Step 4: Do the appropriate arithmetic to determine whether the substitution created a true statement or not. If you created a true statement, shade in the side of the line containing the point selected in Step 2. If you created a false statement, shade in the side of the line that does not contain the selected point. John My calculator said it, I believe it, that settles it

I'm presuming you mean "squares." I don't know what a "squar" is. Lots of ways. 4 by 100, 2 by 200, 1 by 400. Even 20 by 20 (just because something is a square doesn't make it any less a rectangle) John My calculator said it, I believe it, that settles it
 Quadratic_Equations/520390: A rectangular field is fenced in by using a river as one side. If 1800m of fencing are used for the 385,000m^2 field, find its dimensions. 1 solutions Answer 346040 by solver91311(20879)   on 2011-10-24 18:35:47 (Show Source): You can put this solution on YOUR website!

Same idea as saying 6 apples plus 5 apples -- just that instead of apples, you are counting some number of 's. Just remember that if is an apple, then is a banana, and or any other letter is something else entirely. Furthermore, in math, no fair saying "Oh, look, fruit salad" -- you have to keep the like things together and the different things apart. John My calculator said it, I believe it, that settles it
