Answer:
(x, y) ⇒ (x -m, y -n)
Step-by-step explanation:
Reverse the arrow and solve for the x and y on the left:
(x +m, y +n) ⇒ (x, y)
This resolves to two relations:
x + m ⇒ x
x ⇒ x - m . . . . . subtract m
and
y + n ⇒ y
y ⇒ y - n . . . . . . subtract n
Putting these back together, we have ...
(x, y) ⇒ (x -m, y -n) . . . . . maps P'Q' to PQ
_____
The original translation was right m and up n. The reverse translation is left m and down n. That is what the rule shows.
Answer:
C. 1:27
Step-by-step explanation:
a²/b²=1/9 => a=1 and b=3

Step-by-step explanation:
so first you graph the triangle
count how many units one point is from the other point
and if it's hard to count the units (maybe bc the line is diagonal) use the distance formula or the Pythagorean theorem
Answer:
257142857143 / 100000000000.
Step-by-step explanation:
2.57142857143
= 2 + 57142857143 / 100,000,000,000
= 200,000,000,000 + 57142857143 / 100,000,000,000
= 257142857143 / 100000000000.
