Answer:
3 students
Step-by-step explanation:
If everyone in the class has either a pierced nose or ear, we just simply have to add up the total number of hands raised and minus the number of students in the class.
35+8=43
43-40=3
3 students have both a pierced nose and pierced ear.

18 ÷ 2 = 9
Answer:
2) Vertical translation of 10 units
Step-by-step explanation:
Given
H and H'
Required
Which maps H to H'
First, we pick the coordinate of any point on H

First, we pick a corresponding coordinate on H'

The above coordinates show that H and H' are not a reflection of one another because neither of the x or y coordinates negate one another.
By looking at the coordinates of H and H, we have:
H:
and H':
--- The same x coordinates
H:
and H':
--- Different y coordinates
The difference between the y coordinates is:





Hence,
<em>2) Vertical translation of 10 units
</em> is correct.
