Hey guys i need help with these two questions (they from cambridge 3u) Q1. Consider the equations 12x^2 - 4xy + 11y^2 = 64 and 16x^2 - 9xy + 11y^2=78 (a) by letting y = mx show that 7m^2 + 12m - 4 = 0 (b) hence, or otherwise, solve the two equations simultaneously Q2. (a) Find x...

Hi a new maths game ^^ Rules: Answer a question and then ask a question, anywhere from 2unit prelim to 3unit. Have fun guys. I'll post the first question, If, x + y=1 and x^3 + y^3=19 find the value of x^2 + y^2

Preliminary Physics Queation, The captain of a yacht wished to find the distance between the trough and crest of the waves that pass him to aid him during a race. He knows that the velocity of the wave is 42.3m/s and that 6 waves pass him in 3.6s. He predicts his desired distance to be 13m...

hey guys at the request of h3ll h0und i started this thread. any general discussion of dota. discuss strategies, paying each other out about their noobness etc. will be accepted.

i need help with this question thanx in advance sory for my failing... two roots of x^3 + mx^2 + 15x - 7 = 0 are equal and rational. Find m. ok ive done this so far let the roots of the equation be a, a and b. 2a + b = -m a^2 + 2ab = 15 a^2b = 7 so when i rearrange the...
