Question

PLEASE my school years almost over I NEED THIS GRADE and I have no idea where to start id be okay with someone showing me how to do it

A triangular pyramid is defined by the points .The pyramid is then reflected over the xz-plane. The reflected image is then translated 3 units back, 2 units left, and 4 units up.
Write the general rule you use for the reflection.
Show the results of your calculations for the reflection.
Write the general rule you use for the translation. (Hint: Begin with the result of the rule for the reflection.)
Show the results of your calculations for the translation.

Answer 1

The rule for the reflection of the xz-plane:
(x, y, z) --> (x, -y, z)
(x, y, z) --> (x – 3, -y – 2, z + 4)


b. P (0, 5,4) --> P’ (-3, -7, 8)
Y (-2, 7, 4) --> Y’ (-5, -9, 8)
R (0, 7, 4) --> R’ (-3, -9, 8)
A (0, 7, 6) --> A’ (-3, -9, 10)


c. The rule for the translation of the xz-plane :
(x, y, z) --> (x – 3, y – 2, z + 4)


d. P (0, 5, 4) --> P’ (-3, 3, 8)
Y (-2, 7, 4) --> Y’ (-5, 5, 8)
R (0, 7, 4) --> R’ (-3, 5, 8)
A (0, 7, 6) --> A’ (-3, 5, 10)
 Hope this helps!!!!! :DD
