. 2x-2y=8 (answer)
There should be one more equation. Anyways 2y = 2x - 8 y = x - 4 This is a straight line equation with slope = 1 and y intercept = -4 :)

In other word how many ways 2 men can be chosend from a group of 8 and and 4 women from a group of 16 8P2 x 16P4 = 8 factorial / (8-2)factorial x 16factorial/(16-4)factorial => 8x7x6x5x4x3x2x1/6x5x4x3x2x1 ...
9P3 = 9 factorial/(9-3) factorial = (9x8x7x6x5x4x3x2x1)/(6x5x4x3x2x1) = 9x8x7 = 504 :)
8C2 = 8 factorial/((8-2)factorial x 2factorial) = 8x7x6x5x4x3x2x1/(6x5x4x3x2x1)(2x1) = 56/2 = 28 :)

Wave speed = frequecy x wavelength Frequency = wave speed/wavelength 1. In an open tube antinodes are located at the ends of open tube. Minimum number of waves that can fit in an open tube with minimum number of nodes and antinodes is λ/2. Next higher number of wavelengths...
y= (2x-5)2 - 3(2x-5) -4 => 4x2 +25 - 20x - 6x + 15 -4 = 4x2 -26x + 36 => 4x2 -18x -8x +36 = 2x(2x-9) -4(2x-9) = (2x-4)(2x-9) :)

Start with a right angled triangle. Adjacent side = 12, opposite side = 1 is given to you. 1.5 meters given to you is opposite side. Adjacent side you can calculate. Since the slope must be same 1/12 = 1.5/x x = 12 times 1.5 = 18 That means...
Rate of change of deaths = change of deaths/chnage of time = (33963-43510)/(2009-2005) = -9547/4 => -2386.75 deaths/yr :)
