Math Is Fun Forum

Given the coordinates (2, 10) and (5, 60) Write the exponential equation whose graph contains these points.
y=km^x
so i substituted
10=k(m^2)   and
60=k(m^5)
im thinking m^2=10/k   and   m^5=60/k

and going forth like that

name is jonathan, i joined this cuz i love math as much as i like playing my alto sax(which i do like to play a lot). im a sophomore in high school but i learn fast and am fast on solutions within the extenet of my knowledge. i joined mathcounts in middle school and was the ranked 3 within our school. now in high school im really lazy about workin cuz no challenges. i recently found out about how i works like normal numbers, and that kept me entertained for a bit. but what i wanna know and this is the reason i joined, is how matrixs work. like

2x+y+z=4
3x+2y-4z=2
x-y+3z=6

i dunno if thats possible just made up numbers, but i learned to solve it with algebra. but when i asked my teacher how to solve it with a matrix he said he wouldn't tell me cuz u learn it in a higher level math course called linear algebra. i looked it up and found so many different things on it but none i could understand.

so wussup everybody?:D:D
