This Blog exists for the collective benefit of all algebra students. While the posts are specific to Mr. Chamberlain's class, any and all "algebra-ticians" are welcome. The more specific your question (including your own attempts to answer it) the better.
I might be forgetting something or then I'm just being stupid.. How would you find the answer to |n|<6 1/4? I read through the sections but I couldn't find help :(
I don't understand the wording of #47..

ReplyDeleteHow would you simplify an expression like -3y+21?
ReplyDeleteFor |n|<6 1/4 ... use our alternative language!
ReplyDeleteThe distance that n is from zero is less than 6 1/4.... Where can 'n' live such that it is less than 6 1/4 units from zero?
Look up (IN YOUR NOTES, OF COURSE!) your definition for a simplified expression... and you'll see "mission accomplished!"
Can someone explain #47 in their own words?
ReplyDeleteoh for #47 I just showed both versions of the problem like n<61/4 and n>-61/4... Is that right?
ReplyDeleteyeah I think so
ReplyDeleteIs it -6 1/4<n<6 1/4
ReplyDelete???
And I like your dragon, Mr.C! ;)
An "AND" compound inequality can be written in either shorthand form:
ReplyDelete-6 1/4-61/4
Both are correct although 4 out of 5 algebra teachers surveyed prefer the shorthand method.
Please remember that "OR" compound inequalities must be written separately.
