Answer:
Step-by-step explanation:
Given is a triangle RST and another triangle R'S'T' tranformed from RST
Vertices of RST are (0, 0), (negative 2, 3), (negative 3, 1).
Vertices of R'S'T' are (2, 0), (0, negative 3), (negative 1, negative 1).
Comparing the corresponding vertices we find that x coordinate increased by 2 while y coordinate got the different sign.
This indicates that there is both reflection and transformation horizontally to the right by 2 units
So first shifted right by 2 units so that vertices became
(2,0) (0,3) (-1,1)
Now reflected on the line y=0 i.e. x axis
New vertices are
(2,0) (0,-3) (-1,-1)
Answer:
2,4,5
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Use the formula for calculate the distance between two points:
Calculate the distance AB. Substitute the coordinates into the formula. Then:
Calculate the distance A'B'. Substitute the coordinates into the formula. Then:
As you can see, the distance A'B' is the distance AB multiplied by 1/2. Therefore, this is the scale factor.
Answer:
84: 7 would reduce to 12:1 or 12
Step-by-step explanation:
See, if you divide 84 by 7, you'd get 12. (Hope this help, I guess :>)
