Best ResponseYou've already chosen the best response.1Do you have an equation for the meteor's path? You're missing some information here.

Best ResponseYou've already chosen the best response.0No, it didn't give me it.. let me double check

Best ResponseYou've already chosen the best response.1I know that y=4x+1 is your equation from the last problem, but you're going to need to post all the problem info. This is the first I've heard of a meteor, lol.

Best ResponseYou've already chosen the best response.1Post the whole problem. This is not a standalone problem. There is missing info.

Best ResponseYou've already chosen the best response.0I think what its asking me is if I had that info what would I do to solve where they would cross since I have my linear equation

Best ResponseYou've already chosen the best response.0It could be simply asking where y=4x + 1 intercepts the xaxis.

Best ResponseYou've already chosen the best response.0Heres the question: If the linear equation of the meteor’s path is known, describe to the captain how to solve where your equation from question 1 and the meteor’s path will cross. Explain any possible methods used in discovering a solution.

Best ResponseYou've already chosen the best response.1Ah, ok. Just DESCRIBE how to FIND the solution.

Best ResponseYou've already chosen the best response.0It just wants to know how would I solve to find out where the would cross..

Best ResponseYou've already chosen the best response.1What do you think? You would have 2 equations... you want to find a point that is on the graph of BOTH equations. how do you do that?

Best ResponseYou've already chosen the best response.1Oh, and it helps that you are told that the meteor's path is modeled by a LINEAR equation. So both are lines.

Best ResponseYou've already chosen the best response.0I don't remember how to do that.

Best ResponseYou've already chosen the best response.0Id do it all in my calculator if i could..

Best ResponseYou've already chosen the best response.0butt im assuming that i would make the x and y chart and graph my lines.. am i correct?

Best ResponseYou've already chosen the best response.1Don't remember? isn't this topic being covered in your class? No, don't resort to your calculator all the time. It's a useful tool, but it doesn't teach you the CONCEPT.

Best ResponseYou've already chosen the best response.1Graphing is one possible method, although it's not very precise.

Best ResponseYou've already chosen the best response.0Mm im doing credit recovery.. so im trying to understand it. i failed algebra 2 because i wasn't paying attention in school and now im a senior and struggling.

Best ResponseYou've already chosen the best response.0Well ok, i want the most precise way. Would that be solving the liner equation? Im not sure...

Best ResponseYou've already chosen the best response.1If you have two equations, say: y=4x+1 y=3x+5 and you want to find a point that is on BOTH of the lines, then you are looking for an (x,y) pair that satisfies BOTH equations. This is called a "system of 2 linear equations in 2 unknowns".

Best ResponseYou've already chosen the best response.0Ok.. sounds sorta familiar how do i find the pair?

Best ResponseYou've already chosen the best response.1Now, I conveniently wrote both of these in the form y={some stuff}... but that's OK, because you can ALWAYS transform a linear equation into that form (so long as it isn't a VERTICAL line, that's the only time you can't). So since y={some stuff} and y={some other stuff}.... the easiest thing in this case is probably to set the "stuffs" equal to one another. That is, they are both =y, so they are both = each other, see that?

Best ResponseYou've already chosen the best response.1That's called "substitution", because I have one equation (actually both in this case, but one is enough) solved for ONE variable, and then I'm PLUGGING THAT IN ("substituting") in the other equation where I see that variable.

Best ResponseYou've already chosen the best response.0I know of substitution.. but i don't remember how to do it. ive done it before though, quite a few times.

Best ResponseYou've already chosen the best response.1So, in my madeup example, I would have: 4x+1=3x+5 And now I would solve THAT for x, just by moving the terms around (add 3x to both sides, subtract 1 from both, and then divide by the coefficient on the x term)

Best ResponseYou've already chosen the best response.1OK, that's fine... that's why I'm walking you through it. :) You should know how to do this, so it's good that you are going back to relearn it now.

Best ResponseYou've already chosen the best response.1Now, once I solve that equation, I'll have a VALUE, a number, for x. That's my x for my solution. Now I just need y. Well, I have two equations, and again  remember what this solution must be: an (x,y) pair that satisfies BOTH equations. So NOW I'm going to take that x I just found, and plug it into either equation, and solve for y. Check the solution (plug both x and y into both equations, and they should be true). After you confirm that it works, THAT is your solution to the system.
