Ok let’s take this example:5 tins of soup have a total weight of 1750 grams. 4 tins of soup and 3 packets of soup have a total weight of 1490 grams. Work out the total weight of 3 tins of soup and 2 packe...
L1 -> y = 3x – 2L2 -> 3y – 9x + 5 = 0L2 3y = 9x − 5 L1 3y = 9x -6Gradient is the same therefore lines are parallel.
In this equation we have two variables (meaning a symbol - usually denoted by a letter - which represents varying values) ‘m’, and ’t’. The question is asking us to make m the subject of this equation whi...
Every straight line can be written in the form y=mx+c.(If they seem completely unfamiliar with concept):M is known as the gradient of the line, which says how steep the line is. The bigge...
By the sine rule, sin-1(5/13)=22.6 degrees.Equally, by the cos-1(12/13)=tan1(5/12)=22.6 degrees.
