the aim of finsing the inverse is making x the subject. To start we need to multiply both sides by: (x-1), giving us:y(x-1) = 2x+1now we need to expand the brackets:yx - y = 2x+1now gather all the x compo...

To find the inverse we're wanting to make x the subject. First start by multiplying both sides by (x-1), this gives us y(x-1) = 2x+1. Expand the brackets giving yx - y = 2x+1. Gather all the x components ...

The alternating current creates an alternating magnetic field across the transformer. A magnetic field develops in the iron core of the transformer. This causes a potential difference to be induced acr...

Red blood cells have a biconcave disk shape, meaning that it increases their surface area and allows for more rapid diffusion of oxygen into and out of the cell.

Red blood ...
