Answer:
So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:
Step-by-step explanation:
First we have a first discount of 40% so then using this condition and assuming that 
represent the initial price, the price after the first discount 
is given by:
That means 60% of the original value.
Now we have another discount of 45% for the 60% reamining after a 2 discount so let's 
represent the price after the second disccount we can can express this price in terms of or liek this:
So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:
The composition of the transformation is (b) A rotation of 90° and then a translation left 2, up 4.
<h3>How to determine the transformation?</h3>
The transformation rule is given as:
r (90, 0) T(−2,4)
The r(90,0) represents a rotation of 90 degrees.
The other part of the transformation rule can be rewritten as:
T(-2,4) => (x - 2,y + 4)
This means a translation right by 2 units and up by 4 units
Hence, the composition of the transformation is (b)

Given:
A straight-line graph has gradient 4 and crosses the y axis at (0, −3).
To find:
The equation of the given graph.
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope of the line and b is the y-intercept.
A straight-line graph has gradient 4. It means the slope of the line is 4.
Line crosses the y axis at (0, −3). So, y-intercept is -3.
Putting m=4 and b=-3 in (i), we get
Therefore, the equation of the given line graph is .
