x=4

y=3

Specific heat capacity does tell you how much energy a substance needs to increase their temperature and so substances with a low specific heat capacity (SHC) will increase in temperature more rapidly tha...

Firstly, let's rewrite each of these equations as the equation of a line i.e. in terms of y. So we have:

(1) y = 4x/3 - 11/3

(2) y = 2 - 3x/2

Draw line (1) on a graph. The (x,y) co-or...

The answer is: (4X1000)-(12X330)= 40, ao 40 ml more. You may wonder why 1 litre is 1000, as 1 litre of cola= 1000 ml of cola so we have to convert 1 L to 1000ml in the anwer. Rob buys more cola than Jodie...

I think the best way to show how to do this is with an example

"Factorise 6x² + 7x - 3"

Looking at that expression, we can't factorise it straight away, so we'll have to...
