if f(x) = 7x-1 and g(x) = 4/(x-2), solve fg(x) = x

fg(x) = 7(4/x-2) -1 = x 28/(x-2) - 1 = x 28/(x-2) = x +1 28 = (x+1)(x-2) 28 = x 2 - x - 2 0 = x 2 - x - 30 0 = (x-6)(x+5) x=6 x=-5

I want to buy 1 litre of milk. My options are to either buy 250ml bottles for £1 each or 500ml bottles for £1.50 each. Which is the cheapest way for me to buy 1 litre of milk?

If you were to buy 250ml bottles you would need four meaning - 250 x 4 = £1 x 4 = £4. If you were to buy 500ml bottles you would need two meaning - 500 x 2 = £1.50 x 2 = £3. Therefore it is cheaper to buy tw...

Three forces (4i + 7j)N, (pi +5j)N and (-8i+qj) N act on a particle of mass 5 kg to produce an acceleration of (2i - j) m s 2 . No other forces act on the particle. Find the resultant force acting on the particle in terms of p and q. THEN find p and Q

Three forces : (4 i + 7 j )N , (p i +5 j) N , (-8 i +q j ) N Mass = 5 kg acceleration = (2 i - j ) A.Collect like terms (4+p-8) i +(7+5+q) j = (-4+p) i + (12+q) j B. Recal_ f=ma therefore: 5(2i-j)=(-4+p) i +...
