Answer:
or x+3/x
Step-by-step explanation:
Using D.O.T.S (difference of two squares) formula :


Factorise the second bit:

Now write out this fraction:

Now we can cancel out repeated terms (x-3):

This is our final answer:

Answer:
a) The basic rate of pay is 6 sterling pounds per hour.
b) The higher rate of pay is 10 sterling pounds per hour.
Step-by-step explanation:
Both segments of the curve are first order polynomials, which means that each have constant slopes.
a) The basic rate of pay is the value of the slope (
), in sterling pounds per hour, of the line for the first 20 hours worked, that is:
(1)
Where:
- Change in hours worked, in hours.
- Change in pay, in sterling pounds.
If we know that
and
, then the basic rate is:



The basic rate of pay is 6 sterling pounds per hour.
b) By using (1), we calculate the higher rate of pay below. If we know that
and
, then the higher rate is:



The higher rate of pay is 10 sterling pounds per hour.
A perpendicular slope is equal to the negative reciprocal of the given slope, which is 3/4.
The reciprocal of 3/4 is 4/3. The negative of that is -4/3.
Final answer: B
