Answer:
Point A:
(3, -5)
Point B:
(6, -2)
Point C:
(5, -7)
Step-by-step explanation:
Background:
Moving to the right means adding to the x.
Moving to the left means subtracting from the x.
Moving up means adding to the y.
Moving down means subtracting from the y.
So take each point and add 3 to the x, and subtract 4 from they y.
Point B:
(3, 2) → (6, -2)
Point A:
(0, -1) → (3, -5)
Point C:
(2, -3) → (5, -7)
First equation is: x - y = 12
x = 12 + y
Now, substitute this in 2nd equation,
2x - 3y = 27
2(12+y) - 3y = 27
24 + 2y - 3y = 27
-y = 27 - 24
y = -3
In short, Your Answer would be -3
Hope this helps!

Answer:
$141,557.76
Step-by-step explanation:
Chao bought a boat for 160,000
The value of the boat reduces by 4% every year
Therefore the value of the most at the end of three years can be calculated as follows
= 100%- 4%
= 96%
= 160,000 × 96/100^3
= 160,000 × 0.96^3
= 160,000 × 0.884736
= 141,557.76
Hence the price of the boat after 3 years is 141,557.76
