Answer:
a.ABCD is reflected over both axes.
Step-by-step explanation:
Reflection over x-axis transforms point (x, y) into (x, -y)
Reflection over y-axis transforms point (x, y) into (-x, y)
Then, reflection over both axes transforms point (x, y) into (-x, -y). Applying this rule to figure ABCD:
A (-2, 2) -> (2, -2) which corresponds to point A'
B (-1, 2) -> (1, -2) which corresponds to point B'
C (-1, 1) -> (1, -1) which corresponds to point C'
D (-3, 1) -> (3, -1) which corresponds to point D'
Answer:
The answer is B - 1/2.
Step-by-step explanation:
I got it right
A)
If 100 increase to 116
so (101×116)/100 = 117.16
answer is £117.16
B)
If 100 decrease to 79
so (36×79)/100 = 28.44
answer is £28.44
