Answer:
R (1/3 ,1)
S = (2,4/3)
T= (4/3,2/3)
Step-by-step explanation:
RST becomes R'S'T' by multiplying by 3
To get back to RST we need to divide by 3
R =(1/3, 3/3) = (1/3 ,1)
S =(6/3,4/3) = (2,4/3)
R(1/3, 1), S(2, 4/3), T(4/3, 2/3)
Dilation by a factor of 3 about the origin multiplies each coordinate by 3. To find what was multiplied by 3 to get the given coordinates, we divide the given coordinates by 3.
It's the 2nd one
Step-by-step explanation
answer is 20
6/3=2
2×3²=18
18+2=20
9
1 = 32
the total is 180 so 180 - 148 = 32
