Using transformation rules, it is found that the correct option is:
No, A'C'B' is located at A(-1,1), C'(-3,4) and B'(-5,1).
--------------------
- The transformation rule for a reflection over the x-axis is
- The transformation rule for a rotation of 180º is
- After the reflection over the x-axis:
- Taking the reflection, and rotating:
.
- Not the same rule, that is,
, so it would not map figure onto itself.
- A(1,1) would be mapped to A(-1,1), for example, thus, the correct option is:
No, A'C'B' is located at A(-1,1), C'(-3,4) and B'(-5,1).

Dana can type 90 words per minute.
Since, 1 minute = hours
Therefore, number of words she can type =
= 90×60
= 5400 words per hour
If she types words in 'x' hours.
Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time
=
Therefore,
hours
Therefore, Dana types words in 48.15 hours.
