Determine B
When a point is translated up, the result is:

Where h is the unit translated
y' is the new point and y is the previous;
So, we have



When a point is translated left, the result is:

Where h is the unit translated
x' is the new point and x is the previous;
So, we have



Hence, the coordinates of B is

Answer:
A

Answer:
x = 0.
Step-by-step explanation:
5x - 15 = 5(-4x - 3)

25x = 0
x = 0.
Answer:
For maximum area, all of the wire should be used to construct the square.
The minimum total area is obtained when length of the wire is 10m
Step-by-step explanation:
For maximum, we use the whole length
For minimum,
supposed the x length was used for the square,
the length of the side of the square = x/4m
Area =
For the equilateral triangle, the length of the side = 
Area = 
Total Area =
+ 

, therefore it is minimum


x = 10.00m
