Answer:
See below
Step-by-step explanation:
1. First (x+10,y), -> (x,-y)
You add +10 to the x of each point moving the triangle horizontally and then you reflect it across the x-axys.
2.
a) Original point (5,3) -> (x+5,-y )
(5+5, 3(-1)) = (10, -3)
b) Original point (-2,7) -> (x+5, -y)
(-2+5, 7(-1)) = (3, -7)
3. The rule for counterclockwise rotation 90° is (x,y) -> (-y,x )
P = (1, -1) -> (1, 1)
Q = (3, -2) -> (2, 3)
R = (3, -4) -> (4, 3)

The number of possible arrangements of n elements is given by:
In how many different ways can the teams be chosen so that the number of employees on each project are as follows: 9, 4, 2?
This is:
Arrangement of 9 elements, followed by an arrangement of 4 elements followed by an arrangement of 2 elements. So
