Step-by-step explanation:
A. Reflection
When you reflect a point (x, y) across the x-axis, the x-coordinate remains the same, but the y-coordinate gets the opposite sign.
Thus, D (-3,-1) ⟶ D' (-3, 1)
B. Translation
When you translate a point horizontally, its x-coordinate changes, but the y-coordinate. remains unchanged.
You translated the point 3 units to the left.
D'(-3, 1) ⟶ D"(-6,1)
You know that 1 km=1000 m, then the length of the road km is
metres.
A group of 8 people are picking up litter along the road and each person is assigned an equal section of the road. The whole road has length 800 m, then for each person will be assigned 800:8=100 m of the road.
If you want to know the length of each part in km, then 1 m=0.001 km and 100 m =1 m·100=0.001 km ·100=0.1 km.
