The error in the process is we have to add the coordinates john subtracts the coordinates.
The transformation coordinates are (8, 12).
Given that
John says the transformation rule (x, y) Right-arrow (x 4, y 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2).
We have to determine
What was his error?
According to the question
A preimage or an inverse image is the 2D shape that we used to denote before any transformation.
Image is the figure that we get after transformation.
The coordinates of preimages are (4, 5).
Then,
After transformation the co-ordinates are as follows;
Hence, the transformation coordinates are (8, 12).

Answer:
f(x) = 5(4)^x
Step-by-step explanation:
Answer:
a) 10
b) The $40+5 dollars for every ticket
c) See below
Step-by-step explanation:
a)
1. Let t=number of tickets
2. Writing an equation
Breaking even means that you earn the same amount of money for both.
40 +5t=70+2t
3. Solving the equation
40 +5t=70+2t
5t-2t=70-40
3t=30
t=10
So the answer to a) is 10.
b)
1. Using an equation
We already know that there are 2 equations for this problem. (40+5t, 70+2t)
So, we will substitute 20 for t.
40+5*20=40+100=140
70+2t=70+2*20=110
2. Comparing equations
140>110, so the first offer is better
C)
The owner lets you choose how you get paid because one option will be better for you, as some days you might not sell many tickets (so you will go with the $70+2 tickets), or some days you might sell many tickets (you will choose the $40+5 dollars/ticket).
Answer:
£1290
Step-by-step explanation:
35%+40%= 75%
£600=25% £600÷20=30 25%of till = 30 notes 100%=120 notes
40% of 120 =48notes 48x10=£480
90notes-48notes=42notes
42x£5=£210
£600+£480+£210=£1290
