Answer with explanation:
The Statement, When an image has a point of symmetry, then any line containing that point will be a line of symmetry, is false Statement.
This can be explained by taking a line segment of definite length.Draw perpendicular bisector of that segment.That will be line of Symmetry of that segment, because that line will divide that segment in two equal parts.
Now, Mark the point of intersection of segment,and it's perpendicular bisector as M.This is point of Symmetry of that segment.
As, you must be aware that, Through a Point , Infinite number of lines can pass,out of them , only one line which is perpendicular to segment is line of symmetry.
All other lines ,apart from perpendicular line ,is not line of symmetry passing through that point.

Answer:
--- Running cost
--- Monthly income
71 cars
R1775
Step-by-step explanation:
Given
Expenses
per car
Income
per car
Solving (a): Expression for the running cost
This is calculated as:
Where
y = Total running cost
x = number of cars
So:
Solving (b): Expression for monthly income
This is calculated as:
Where
y = Total income
x = number of cars
So:
Solving (c): Break even
To do this, we equate the expressions in (a) and (b)
Collect Like Terms
Solve for x
Solving (d): How much to break even
Substitute 71 for x in any of (a) or (b)
<em>Solving (e): There is no question to answer on the "graph"</em>
