Answers:
<h2>(7, 9), (13, 0), & (15, -4)</h2>
Step-by-step explanation:
1st Pair
X 2 + 5 = 7
Y -3 - -12 = 9
<em>First transformation new coordinates: (7, 9)</em>
2nd Pair
X 8 + 5 = 13
Y -12 - -12 = 0
<em>Second transformation new coordinates: (13, 0)</em>
3rd Pair
X 10 + 5 = 15
Y -16 - -12 = -4
<em>Third transformation new coordinates: (15, -4)</em>

Answer:
The answer is c = 25.13 a =50.27
The answer to this question is extremely simple. Think of it this way. When you have 2 apples and you eat one how many do you have left? Well we can use the Pythagorean theorem, a^2 + b^2 = c^2, so 2^2 -1^2 = ?. Well how do you find exponents?
Good. What is the Pythagorean theorem? The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent). Very simple. So you would have one apple remaining.

The formula for the growth rate is given by
Now when b is greater than 1 , then it is increasing function
and when b is less than 1 , then it is decreasing function.
Now in the function
here value of b is 0.88 , which is less than 1 , so it is decreasing function
And decay rate is given by
1-r = 0.88
Subtract 1 from both sides
-r = 0.88-1
-r = -0.12
r = 0.12
or r= 12%
It means it is decreasing at a rate of 12%
Hence Option C is correct
C.The price of the boat decreases by 12% every year.
