I hope so because you all have help me and my friends a lot.If you are not excepting anymore e-mails from this site,could you please let me know,because I was considering sending a donation for all the help you have given me.

Sometimes problems get ignored for no apparent reason. \n" ); document.write( "Sometimes they aren't answered because they are very long problems that will take too long \n" ); document.write( "to explain. \n" ); document.write( "Sometimes the problem is not stated. Only a textbook is referenced and most tutors don't have \n" ); document.write( "a library of all the textbooks that people refer to. Therefore, the tutors don't know what \n" ); document.write( "the problem really is. \n" ); document.write( "Sometimes the problem is typed out in such a way that it can't be easily understood \n" ); document.write( "so tutors won't bother taking time to unscramble and interpret it or won't work it the three \n" ); document.write( "or four ways that it might be interpreted. \n" ); document.write( ". \n" ); document.write( "And sometimes tutors just need a break to so they drop off line for a while. This may \n" ); document.write( "be one of those times when all the tutors are just taking it a little easy ... working \n" ); document.write( "on income taxes, getting involved in politics, and other distractions. Most tutors are \n" ); document.write( "volunteers who provide this free service for fun, just to stay in practice, or just because \n" ); document.write( "it is something that contributes something to others in need and it makes them feel good \n" ); document.write( "to do so. On the other hand, most have jobs and other responsibilities such as families, that \n" ); document.write( "require their attention too. \n" ); document.write( ". \n" ); document.write( "Your problem was written as: \n" ); document.write( ". \n" ); document.write( "4(3y-2)>=992y+5) \n" ); document.write( ". \n" ); document.write( "I think you meant it to be: \n" ); document.write( ". \n" ); document.write( "4(3y-2)>=9(2y+5) \n" ); document.write( ". \n" ); document.write( "You can work this inequality just as you would an equation with one exception ... if you \n" ); document.write( "ever have to divide or multiply both sides by a negative quantity, when you do the division \n" ); document.write( "or multiplication by that negative quantity, you reverse the direction of the inequality sign \n" ); document.write( "at the same time. \n" ); document.write( ". \n" ); document.write( "Let's follow the rules of equation solving in working this problem. First let's do the \n" ); document.write( "distributed multiplication on both sides ... on the left side multiply the 4 by both terms \n" ); document.write( "in that set of parentheses and on the right side multiply the 9 by both terms in that set of \n" ); document.write( "parentheses. These multiplications expand the inequality to: \n" ); document.write( ". \n" ); document.write( "12y - 8 >= 18y + 45 \n" ); document.write( ". \n" ); document.write( "Get rid of the 18y on the right side by subtracting 18y from both sides to get: \n" ); document.write( ". \n" ); document.write( "-6y - 8 >= + 45 \n" ); document.write( ". \n" ); document.write( "Now get rid of the -8 on the left side by adding + 8 to both sides and you have: \n" ); document.write( ". \n" ); document.write( "-6y >= 53 \n" ); document.write( ". \n" ); document.write( "Finally, solve for y by dividing both sides by the -6 that multiplies the y. And don't \n" ); document.write( "forget that since you are dividing by a minus quantity you must also reverse the direction \n" ); document.write( "of the inequality arrow. When you divide both sides by a minus 6 the inequality becomes: \n" ); document.write( ". \n" ); document.write( "y <= -53/6 \n" ); document.write( ". \n" ); document.write( "And thats the answer to your problem ... y must be equal to or lie to the left of -53/6 \n" ); document.write( "on the number line. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand how to do inequalities such as these. \n" ); document.write( ". \n" ); document.write( " |
