(1) 5(3x - 2y) = 14 -2ax 15x - 10y = 14 - 2ax (2) 15x +2ax -10y = 14 15x + 2ax = 10y + 14(3) x(15 + 2a) = 10y + 14 x = (10y + 14) / (15 + 2a)To asking us to make x the subject of a fo...
From first equation: 3xy = 1 => x = 1/(3y)Substitute expression for x into second equation: y = 12x + 3 => y = 12(1/3y) + 3 = 4/y +3Multiply through by y: y2 = 4 + 3y => y2Answered by Hallam M. • Further Mathematics tutor2012 Views
(a) let A be (x1,y1) and B be (x2,y2), Gradient = m = (y2-y1)/(x2-x1) m = (4- -5)/(-1-2) = 9/(-3) = -3 Gradient = -3(b) equation of a straight line line: y = mx + c => y1 = ...
