nvm i got it yesterday lol thanx anyways

Homework Statement I'm completely stuck on this question I'll write the whole thing down Consider the circle x² + y² = 25 and the line y = x + k. where k is any real number. Determine the values of k for which the line will intersect the circle in one, two or no points. PLEEEASE help me...

XD right sry i feel stupid now um thanks alot

oh yeah right... didnt see that how do u deal with the root properly then lol

thats why it doesn't work out its not quadratic anyways there's no x squared

Im only 14...

the square root of -1 is called i its always called i

well u change it into sqr(25) x sqr(-x^2) then u sqroot the 25 to 5 and the sqr root of -x^2 is sqr(-1) x sqr(x^2) so its 5ix i = sqr(-1)

well if u set the y values to equal each other 3/4x + 35/4 = sqr root of (25 - x^2) you get 0 = -3/4x + 5ix + 35/4

so wait this function 0 = -3/4x + 5ix + 35/4 has no real solutions because there is a complex number right?

now i just need to show that the circle and the line don't intersect algrebraecally or however you spell it.

well i graphed it and it showed no intersection

i kno but i gor to 0 = -3/4x + 5ix + 35/4 and i don't really kno how to solve that

ah can someone do this for me please, I'm stuck

oh sry didnt see that
