Like Carol said, when you graph the two lines, they intersect. You can go to this link and type in the equations to see their graphs:
https://www.desmos.com/calculator
For #1 the lines intersect at (-4,3) and for #2 the lines intersect at (6,2).
we got those answers, the book says there both wrong.... #1's answer is 3,6 and #2's answer is -5,1

ok... maybe I have just looked at way to much algebra for today, but now im totally confused!!! I don't even understand how to graph those two equations properly and get the answer they did. ??

does anyone want to help us figure out these 2 problems? the solutions manual doesn't have them worked out! if I plug in the answers they make sense, but we have no idea how they got the answers. we have spent all day reviewing all of chapter 7 in Jacobs geometry ed. 3 (and we have the Callahan dvd's and rewatched chap 7 as well). both dd and I are seriously missing something!
graph the following pairs of simultaneous equations and tell what you can about the solutions ...
(the solutions manual has the problem graphed and the answer to x and y
1. y=x+7
y= -1/2x +1
2. x+2y=10
2x-3y=6

my dd for 10th is going to have several co op classes that are good classes, but wont equal quarter credits. what do I do with them? lol! I hate to just see them count as nothing at all, but her schedule is pretty tight, so teaching more to each of them to bring it to quarter credits probably wont happen. for example she has a 6 hour cpr/first aid/aed certification and a 10 hour logic class on the art of argument. any ideas or thoughts? thanks!

short background, dd is starting 10th grade in the fall and is signed up at the university for English 101 as dual enrollment. she is VERY interested in talking dual enrollment classes although she is sticking rather firmly at the moment to not wanting to attend college after 12th grade (that's a whole different subject lol). so what she wants to do is take dual classes that can transfer over to cover different degrees if she changes her mind. she says if she does attend college after 12th grade, she almost certainly wont want a 4 year degree, so im back to looking at a 2 year specialized degree. ive researched a few different degrees and besides 2 English courses and 1 math course, nothing else on them is "generic". so I don't know what else for her to take that would actually be useful towards that? can any give some advice or suggestions? im new to the dual enrollment idea, since we only found a loop hole 2 weeks ago where a 10th grader could even attend and she jumped on it ;) thanks so much!

I just recently heard about this :) dd is starting dual enrollment in the fall for 10th grade for English and a few people have suddenly suggested that she not take any math classes for dual so she can try to test out for credit in math. can someone explain to me what this means?? lol!!! dd was only thinking of a getting a 2 year degree in something particular, so my assumption was to get her core classes out of the way with dual, but now im so confused!!! help! thanks so much :)

has anyone done the online dual enrollment program? I would love the hear anything at all about it! dd will be in 10th grade this coming fall and our dual enrollment in our state doesn't start till 11th, but I was told by our evaluator last week that this is a popular option by some local homeschoolers to take a few classes in 10th grade as dual enrollment online with them at a reduced rate to get ahead. thanks so much!

I just purchased Jacobs algebra with dr callahans dvds for dd and she is devouring them! I wanted to start searching for geometry to have ready at a good price, but im a bit confused. if we use dr callahans dvds for it, then we need to use the 3rd edition of the student book? is that correct? in searching back previous threads it seems most like the 2nd edition better. is the 3rd edition not good or somehow very different? thanks so much for any input :)
-
ok.... so everything I ordered came in and it looks amazing!!! I have the dvds from ask dr calahan, the text, solutions manual and a test booklet from Jacobs (and then theres also the tests that came with dr calahans.
how much of each lesson in the text should I have dd do?? it looks like ALOT of practice problems. can anyone chime in with what they do??? thanks!!!!!
-
just throwing it out there, but my dd likes the books you listed as well and she did a whole literature study last year on the original fairy tales especially Arabian nights being a favorite :) not sure if this counts as literature or not, but theres also the divergent series that's similar to hunger games.
-
she is thinking of this one:

a friend of hers got one for Christmas and hasn't had any problems with it, so she thought she would give it a try :)

dd , 15, is using her money to buy a VERY inexpensive tablet for herself :) basicly just to play around on, nothing fancy at all. since its her money and its only $60 for the tablet, does she need case for it?? im not thinking she would be taking it anywhere, except maybe to the library once in a blue moon. also, does she need some kind of screen skin protector for it? again, I don't want her to throw extra money out if its just being used in her room to play games and Skype lol! thanks for any help!

what do I actually need for dd to take elementary algebra? is there anywhere to see samples of it? best place to purchase? thanks so much!!
-
Two options. One, not to be dumb, but what are you posting from, your phone? I wish they could get their online stuff ready. I think they're talking about a streamed version. If you have a computer and it doesn't have a disk drive, you can get a disk drive for $30 from Best Buy.
Two, use the textbook from your TT level.
yep, my phone :) we don't have a computer at all at this point. I surpose I could look into a I pad style and add on the dvd drive ? but I know nothing at all about those lol!!!
we don't currently have the textbook, but im thinking she really needs the lecture parts on some of them to understand the concepts. that was what was helping her....

dd was using life of fred for math and doing very well at it when I suddenly realized she wasn't retaining much. she had gotten through algebra 1 in life of fred. so I panicked and had her do a placement test in teaching textbooks and decided it was best for her to do a quick review of prealgebra and then move back into algebra 1. well, today our computer crashed!!!! we so do not have the money to purchase another one right now, so now I have no idea what on earth to do with her math!!!! she was only at lesson 35 in algebra 1..... but she was struggling some. if I put her back to something offline or non computer based, I have no clue what to use!!! any help at all?? she hated MUS by the way, so that's out. she doesn't need anything rigourous, just math that covers what she needs to know and needs no help from me. any input would be great! thank you!
-
that there not using for this fall semester?? theres a course dd is dying to take, but we just cant afford the cost of it and I have heard good reviews from them. thanks!
-
the iliad would be first ;) and if only reading one I would say the odyssey!
-
agree with the others and dd just started it and is so far enjoying it :)
-
I agree with the others, I wouldn't skip it. if anything, test out of the few chapters at the beginning of prealgebra as said above. dd was able to skip to chapter 5 that way ;) hope that helps!
-
omgosh! how did I miss all that??? LOL!! thank you so much!!! does the actual writing of the report sound well written?
-
well, I think I would say its a book report retelling the tale of his return home to peneolpe :) she wanted to spin it differently than a usual old book report, so I let her have free reign on how to steer that part of it ;)

yes this is what we got for answers, the solutions manual has different answers though (see other post).... :)
