Answer:</h3>
B. (0, 9)
<h3>
Step-by-step explanation:</h3>
Reflection across x=a is represented by the transformation ...
... (x, y) ⇒(2a-x, y)
Reflection across y=b is represented by the transformation ...
... (x, y) ⇒ (x, 2b-y)
The double reflection, across x=2, y=1 will result in the transformation ...
... (x, y) ⇒ (2·2-x, y) ⇒ (4-x, 2·1-y) ⇒ (4-x, 2-y)
For (x, y) = X(4, -7), the transformed point is ...
... X''(4-4, 2-(-7)) = X''(0, 9)
The two numbers in each column have to add to 23
So under 7 you write 16, above 4 you write 19, etc
The rule will say x + y = 23
Answer:
What? I think you forgot to attach the picture.
87 because 13.688 is way less than 87
Answer:
The formula for calculating speed is:
S (speed) = D (distance) *divided by* T (time)
or just simply without labels:
S=D/T
In the problem u'r doing 9/4 (hope i see it correct) represents D, 1/2 represents T, and 4.5 represents S
Hope this helps)
