Given that △XYZ is mapped to △X'Y'Z' using the rules (x, y)→(x+5, y−3) followed by (x, y)→(−x, −y) .
We know that (x,y) => (x+h,y+k) type operation represents translation so rule (x, y)→(x+5, y−3) will cause translation.
We know that (x,y) => (-x,-y) type operation represents rotation about origin so rule (x, y)→(−x, −y) will cause rotation.
So combining both results and comparing with given choices. we find that only 1st choice "△XYZ is congruent to △X'Y'Z' because the rules represent a translation followed by a rotation, which is a sequence of rigid motions."
is correct.
Answer:
12
Step-by-step explanation:
The average of 3 numbers is their total divided by 3.
(150 +205 +178)/3 ≈ 178.67

Step-by-step explanation:
87 degrees minus 10 degrees would give you 77 (which is the lowest temperature). then 77 degrees plus 17 degrees is 94 degrees. the difference between the highest temp and lowest (94-77) would be 17.
