We will begin by eliminating fractions in the equation. To do this, the equation will be multiplied by 4 and (x+2), as these are the denominators of the two fractions.
Multiplying by 4 gives:x - (8x/...

It relates back to what we actually mean why we say dy/dx. Simply put, dy/dx means the rate of change of y with respect to the rate of change in x over a infinitely small space of time. Therefore, when we...

We approach this question using algebra.Lets say the price of teas=x, and the price of coffees = ytherefore 2 equations can be written:3x+2y=7.805x+4y=14.20we now treat these equations as simultaneous equ...

The first step in figuring out this question is to first determine what the y=x³ looks like.If you are not already fimilar with this function, you can use some basic principles to find out wha...

laws of indices state that the denominator of the fraction is the root of the number or letter, and the numerator of the fraction is the power to raise the answer to. Therefore, first we...
