On a straight line graph, the lines are formed by an equation in the form y=mx + c . The m value in this equation represents the gradient, and the c value is the y-intersect.If two lines are parallel, this m...

x = 5

To expand this we multiply the first term in each bracket together to get x 2 Then we do the first bracket's first term by the second bracket's second term to get -5x The we do the first bracket's second ter...

These equations are what we call 'simultaneous' which means they are solved together. To do this, we need to make one of the variables (x or y) the subject of either of the equations.Rearranging the first eq...

ax 2 + bx + c 1) First factorise the quadratic equationTwo numbers whose product is 'c' and sum is 'b'In this question, c= 6 and b= 76 x 1 = 6 and 6 + 1 = 7So your two numbers are 6 and 1--> x 2 + 7x + 6 ...
