The equation of the line L1 is y = 3x – 2 The equation of the line L2 is 3y – 9x + 5 = 0 Show that these two lines are parallel

L1 -> y = 3x – 2L2 -> 3y – 9x + 5 = 0 L2 3y = 9x − 5 L1 3y = 9x -6 Gradient is the same therefore lines are parallel.

Given f(x) = (x^(2)+(3*x)+1)/(x^(2)+(5*x)+8), find f'(x) and simplify your answer.

Taking: f(x) = (x^(2)+(3 x)+1)/(x^(2)+(5 x)+8) An application of the quotient rule of differentiation is required. This rule is given as: Where g(x) = u(x)/v(x), g'(x) = ((u'(x) v(x))-(v'(x) u(x)))/(v(x)^(2)...
