To differentiate the quotient of two functions f(x)/g(x) you can use the quotient rule, the formula of which is: (f'(x)*g(x)-f(x)*g'(x))/g²(x)

it is important to remember which...

x = 4.5 

Rearrange the equation, so that like terms are on the same side:

5x - 3x = 2 +7

2x = 9

Then to find x, divide 9 by 2

x = 4...

This is the minimum amount of energy reacting particles must have to undergo a chemical reaction.

It can lead to an increase in the population size of strains of antibiotic-resistant bacteria, such as MRSA
