Question 1059011
.
Hello,

if you are a novice in this site, you need/must to know it and to follow it:


<BLOCKQUOTE><TABLE BORDER=2>
  <TR>
  <TD>
 &nbsp;&nbsp;&nbsp;&nbsp;When posting formulas to this forum, use parentheses properly and systematically.&nbsp;&nbsp;&nbsp;&nbsp;


  </TD>
  </TR>

It is <U>THE RULE</U> of this site. 
It is necessary to make your formulas readable and unambiguous.


In other sources, like your textbook etc. the readability is achieved by using special typography means.
This site does not have such means, therefore the only way to make the formulas readable is using parentheses.


I hope that it is sufficient to say it once (one time), and you will follow this requirement.



For example, the way to write your first equation


Y = -2/3x+3


is this:


Y = (-2/3)x+3


(if it is what you want).


And we will know then that it is &nbsp;NEITHER &nbsp;&nbsp;Y = -2/(3x+3)   &nbsp;&nbsp;NOR&nbsp;&nbsp; &nbsp;Y=-2/(3x)+3.
