6 possible ways to order 3 couples in a row
Given,
We have three married couples. that is six persons in total.
a, b, c, d, e, f may taken as the six persons.
Considering the statement:
Elder partner on the left, assume a, c and e as elders.
Then we have, (a, b) ------ ( 1)
(c, d) ------ (2)
(e, f) ------ (3)
There is no change in position between the couples.
So, we get three persons in total.
Possible ways to order these three persons will be like this: 3! = 3×2×1
= 6

Answer:
1) The reflection image of figure 1 is figure 2
2) Figures 1 and 3
Step-by-step explanation:
* Lets explain some transformation
- In the reflection the line of reflection will lie directly in the middle
between the original figure and its image
- Corresponding parts of the figures are the same distance from the
line of reflection
- Reflection does not change size or shape
- Translation moves a shape up, down or from left to right or right to
left but it does not change its shape
* Lets solve the problem
1)
- The reflection image of figure 1 with respect to line m is figure 2
because the distance between each point on figure 1 and the line
m is equal the distance between each point on figure 2 and line m
∴ The reflection image of figure 1 is figure 2
2)
- Figure 3 is the image of figure 1 by translation because if figure 1
moves down by some units it will be coincide with figure 3
∴ The answer is ⇒ Figures 1 and 3
