Question 1011829: "The lines l1 and l2 have equations r=2i+k+s(i-j+2k) and r=3i+8j+t(i+2j-3k) respectively, where s and t are parameters.
The plane p contains l1 and has no common point with l2. Find an equation of p in scalar product form."
I know that if p has no common point with l2, it means l2 is parallel to p. I have read the solution, and it says we need to cross product (i-j+2k) x (i+2j-3k). But how can we cross product (i-j+2k) x (i+2j-3k) ? Doesn't two parallel vector cannot be crossed ? I need your help and further explanation please.
Thank you very much.

Question 1019647: This diophantine equation seems impossible for me..
"A dealer spent $10000 buying cattle, some at $410 each and the rest at $530 each. How many of each sort did she buy?"
I made a diophantine equation for this..

simplifies to:

i seem to have most trouble when the c is the biggest number in the equation in ax+by=c

I tried using euclid's algorithm but it doesnt seem to work for me, i think im using it wrong..
Any help to the question would be helpful.

Question 1020098: Find the distance between the point (-3,1) and the line y = -x+4.
I know first I must find the equation of the perpendicular line, and I get y = -x-2. Then, I must find the point of intersection. In order to do this I know I must set both equations equal to one another as shown here: -x+4 = -x-2. This is where I get stuck. Could you please help me?
