Re: Solve this equation for me
How about learn some 7th grade math?

Re: Solve this equation for me
You're 17 and you can't understand that?
Not sure exactly what you're asking for (both of the functions' equations?), but those are basic linear functions, bro. You should have been able to do that since junior high at least.
ps m is slope, the rise divided by the run, change in y divided by change in x. b is the y intercept, the x value where the line crosses the y axis.

Re: Solve this equation for me
Wait, wait I just got it.
y= -2x+3
That right?Comment

Re: Solve this equation for me
I don't even know what you're asking for.
The equation you gave appears to be correct for the blue line. Not sure what relation the red line is supposed to be or what the "solution" to this "equation" is. Isn't the "answer" to a system of functions usually the point of intersection?Comment

Re: Solve this equation for me
You have two lines in that graph and you asked for only one equation... Which one did you mean?
..and shouldn't this be in Critical Thinking forum?
then again this doesn't even require any critical thinking (for an 11th grader) so not wrong forum i guess
You got one of the lines correct.Last edited by leonid; 10-13-2009, 11:45 AM.Comment

Re: Solve this equation for me
Are you serious son
Blue line is clearly y = -2x + 3 and the red line is clearly y = x - 6Comment

Re: Solve this equation for me
Hey thanks for the help instead of laughing at my thread some of you actually decided to do something about this.
Yes, the last one is y = x-6 my teacher just told me but thanks for trying it out Marcus you're a good fellow.
Thread over.
Peace.

Re: Solve this equation for me
lmao
How about some problems that are actually trickier to solve:
1. A stick of length one is split into two sticks at a random point that is uniformly distributed -- say X is the shorter stick and Y is the longer one. Find E(X) and Var(X), then find E(Y-X)^2
2. Leonid and Rubix are alternating rolling a pair of dice, stopping either when Leonid rolls the sum of 9 or when Rubix rolls the sum of 6. Assuming that Leonid rolls first, find the probability that Leonid has the final roll.
3. Easier one for ya -- you can buy a lottery ticket for $1. If you win, you get $5 back. You're determined to win twice at any cost. Each ticket has p = .125 of winning. What is the probability you get your second winning ticket on the sixth purchase? What's your expected profit or loss from this lottery in general?Comment

Re: Solve this equation for me
Here's a hard one I doubt anyone here will get -- from one of my homeworks:
You have a system of N components. Each component will function, independently, with probability p. The total system of components will work if at least half of them are functioning. For what value of p is a 5-component system more likely to operate than a 3-component system? How about a (2k+1) component system over a (2k-1) component system?Comment
