Make x the subject of the following formula: 5(3x -2y) = 14 - 2ax

(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 formula, the question re...

Solve these simultaneous equations: 3xy = 1, and y = 12x + 3

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: y 2 = 4 + 3y => y 2 - 3y - 4 = 0Factorise: ...

A is the point (2,-5), B is the point (-1,4). (a) What is the gradient of the line passing through points A and B? (b) Does the point (-100,301) lie on the line passing through points A and B?

(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 = m(x1) + c -5 = -3(2) + c c = -...

I don't quite understand when to use the perfect tense vs the imperfect, could you help me please? (making the assumption they understand the conjugation rules already)
