What is the difference between google and a subject directory like yahoo directory or infomine? (site 1)

To begin with, google is a wide platform where a wide range of information can be found. This can range from common questions, to job postings, the weather, biographis, directions<nd the like. Meanwhile, using a source like Yahoo Directory or Infomine is more subject specific and used for smaller scale searches where the information options doesn't need to be as long. In other words, Google is the properly source for general search.

self-monitoring is in other words holding back your emotions for the better good. usually, people who can't hold their excitement, temper, or any other emotions, need to self-monitor themselves.   lol

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
