Thank you!

I have never been taught how to solve a problem like this and am not familiar with Cramer's rule. The only thing I have done so far is adding up the two equations to make one.

Hello. I could use some help with this problem, number 12. Thanks!

Hey guys, I really need help with number 10! I am utterly confused!

I would really appreciate some help with this problem, number 45. The answer is at least seven. How? Thanks!

Thank you both so much! Cheers!

Hey guys. In my Algebra class we have been doing probability. I understand the fundamental ideas, but I have a specific question. I have attached a photo of the problem, number 37. The answer is .5, but I really would appreciate someone walking me through it. Thanks!

No idea how that happened. What I meant to type was: (x^2)/65025 - (y^2)/184975=1

Alright, I think I actually just solved it. I got (x^2)/65025 - Y=(y^2)/184975=1. If someone could confirm, that'd be great!

Hey, guys. I was doing my homework a few nights ago and ran into a tough problem. I still have not been able to figure it out. Any help would be greatly appreciated! Thanks a lot! The problem: An explosion is heard by two people who are 1000 meters apart. One person heard the explosion 1.5...

Yeah, we got it resolved in class. My teacher gave too much information on the problem.

10 is a given length though.

Ok, that makes sense. I think that the problem doesn't work out. It was made by my teacher and a lot of them can't be solved.

Hey guys, I was doing my Geometry homework and I ran into a problem that just does not seem to work. I used the Power of a Point theorem as well as trig functions. I have done each method multiple times and keep getting the same two different answers, one for each method. When I use Power of a...

Awesome, thank you!

Ok, everything makes sense except this. When P, the perimeter, is simplified, it equals 6x+4, derived from 2(x+1)+2(2x+1). So for that to be defined, wouldn't the x values have to be greater than -2/3? If you plug in -2/3 you get zero. Any higher number results in a positive corresponding y-value.

Ok, for 42 part b, I got all real numbers above -2/3 for P, all reals above -1/2 for A, and all reals above -1/2 for R. For 43 part b, I got all reals above zero for all three. And one quick question. For number 42, when it is asking for what values of x define P, or 6x+4, the numerator, do I...

That's all defined means? Haha, thanks.

Hey guys. I was doing my math homework and ran into some trouble with numbers 42 and 43, both are attached in a picture. I could find the rational functions just fine, but I did not quite understand part b. What does it mean for a function to be defined? The answer for part b of number 43 was...

Thank you sir!
