Step 1. Pick one of the equations and move all of the x values to one side of the equal and move all others to the other side e.g X = 2y + 3Step 2. Make sure the X value is not times by a number e.g 2...
First you need to remember the equation area of a circle = πr2 with r being the radius. Therefore as we are given the area of the cicle we need to rearrange the equation to give us the radius. ...
First gather all x terms on left hand side,7x2-13x-2=0.Since 7 is a prime number we can begin factorisation,(7x+/-?)(x+/-?)=0.We know there must be a +/-2 and +/-1 in place of the q...
To answer this question, you should make use of the general equation of a straight line: y=mx+c.For two lines to be parallel, they must have the same gradient (i.e. the same coefficient of x- which in the...
All three are types of averages that we can calculate.1, 1, 4, 6, 8, 12, 17We can calculate the mode by looking at which number is the most frequently occurring number, for example, with the above d...
