We have the following transformations:
y = f (x + c): moves the graph c units to the left.
y = 10 (x + 2) -10
y = 10x + 20-10
y = 10x + 10
y = f (x) - c: move the graph c units down.
g (x) = 10x + 10 - 12
g (x) = 10x - 2
Answer:
the function g (x) is given by:
g (x) = 10x - 2
If a person bought 8 items and each item was priced at $4, that means the total amount spent was $32.

The person received 8 dollars in change. This means that the person payed 8 dollars more than what they spent. Well, we just found out how much they spent, so we can find out how much money the person gave the vendor.
Let p = amount of money paid by the person.


The person gave the vendor $40.
I guess its 40 meters since
Area of a square is (Length)^2
and The area is 100, so square root that and you get your length which is 10 meters.
and since perimeter is the sum of lengths of sides, and a square has 4 sides, your perimeter is 40 meters! :)
