(using Pythagoras' theorem) 6.5² = x²+ 1.5² x²= 6.5²- 1.5² x²= 42.25 - 2.25 x² = 40 x = sqrt(40) x ...

There are different rules when it comes to indices. First of all we will look at the example of multiplying two expressions . For example, y² x y⁴ . Here we need to do the addition r...

5th Term is a+18b=442nd term is a+ 6b=8subtract the two equations from eachother to get 12b=36 rearrange so that b=36/12=3 substitute b=3 into any of the above equations to get a; a=8-(6x3) = -10 so a=-10...

First we need to list what we know from the text. Bob's speed : 13,48 mph and 6hour a day. The distance is 392,5 miles. How do we get the number of hours? Distance/Speed = 392,5/13,48 = 29,1172~ 29,12hour...

step 1: re-arrange the function in a nicer wayx = (y + 4)/44x = y + 4y = 4x - 4step 2: draw the graphthis is a stright line going through y axis at -4 and x axis at 1, with gradient of 4
