find the equation of the line that passes through the point of intersection of the lines x-3y=4 and 3x+y=2 and is perpendicular to the line 3x+4y=0. Give your final answer in the form ax+by+c=0 where a,b and c are integers to be determined.\n \nfirst we find the point of intersection\n\nx-3y=4,3x+y=2\n\n>>>>x=1,y= -1\n\ntherefore, point of intersection of two lines\nis(1,-1)\n\n3x+4y=0\ny=(-3/4)x\n\nthe gradient of line perpendicular to this line\n= -1/gradient\n\nperpendicular line passes through (1,-1) and \nhas a gradient of 4/3\n\nequation of perpendicular is\n\ny=4/3x+c  say\n\nsubstitute values at point(1,-1)\n\n-1= 4/3+c\n\n>>>>>c= -7/3\n\nequation of line is y=4/3x-7/3\n\n>>>>>3y-4x+7=0 \n\ntherefore, the equation of the line that passes through the point of intersection of the lines x-3y=4 and 3x+y=2 and is perpendicular \nto the line 3x+4y=0 is\n\n3y-4x+7=0\n\nwhen doing these problems,it helps to draw \na rough graph of the situation\n\nanother answer could be\n\n4x-3y-7=0 or 300y-400x+700=0\n\ni hope that this helps

You should probably go see your tutor at school for help.  You never know what kind of answer someone is going to give you...or if they are just messing with you.

first make sure you have the basic math skills down, then do problems...do problems and then do more problems...lots of practice can make anything easier...unfortunately there is no way to get around this...

Dont say you cant do it. You can as long as you make up your mind. You know if you work in a group, for example,  get your friends, and do group studies.I know that they will be willing to go an extra mile to build you up on your weakest points in mathematics. I  tell you this, because it happened to my son, and he was successful when he tried this. Good luck

Well we are not going to do your homework for you. But we will help you along. why not start out by writing down everything you know. they writing down what you need to find. Then look at your equations and find one that uses what you know to find one of the values you need to find.\n\nSo write it up and put it on here and we will help you along.

I see by your previous questions that you are literally writing in all of your homework questions.  \n\nMy advice to you:  They teach it for a reason, it may be a pain in the butt to learn, but it's worth it.  \n\nDon't sell yourself short by getting someone else to do your work.  \n\nBesides, it is pr oven that solving math problems keeps your brain from getting lazy and keeps you younger in the long run.\n\nGo grab a pencil and get to work.

learn lots of tricks.  They help you to do computations faster.  \n\nFor eg., like this question:\n\n379x231+391x1269\n\nYou would probably go, OMG, this is impossible.  \n\nBut if you take the 391 out from both sides you get \n\n391(231+1269)\n\nwhich = 391x1500\n\nSuddenly it's not so hard.  \n\nHere are some good sites:\n\nhttp://www.angelfire.com/me/marmalade/mathtips.html\n\nhttp://www.curiousmath.com/\n\n\nGood Luck!

Your computer has a calculator built in.  Failing that, try long division.  You're gonna have to learn how to do it anyway.\n\nSheesh.

Someone might help you do your homework but you will find it hard to find someone to do your homework. Give it a shot and then ask for someone to look it over.

you need to do a bunch of problems to get comfortable with formulas and with the math.  just do all the problems in the back of the book and you'll be fine.  if you're still having problems go see your professor or TA

you've posted this question about six times! Are you not intending to do your own homework at any point of the day or do you insist on never learning how to do it by getting the rest of the world to do it?!\n\nDo your own homework and learn something!

Anything you do not do is a zero, anything you do even not so well is some points. Do all of it if you can.\nFind which assignments carry the most weight or points. do those, then look at all the ones you can do easily and attack those. then find some help for the ones you find more difficult.\ntake breaks after certian amounts of time and then go right back. You made a mess but you can dig out of it. Good luck.\nsites that may help: wikipedia, enchanted learning, sosmath, math.com, world fact book\ngood luck

Based on number of questions you are asking, it looks like you're trying to get the answers for your whole homework assignment.  Since most of these are fairly easy problems, I'd suggest you spend some time working them and making sure you know how to differentiate.  Trust me, you'll do better in your class if you work some of these on your own.

you need to do a lot of exercises, ask your teacher a lot of questions, and work on your math every day... \ngood luck!!!!!!
