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:
x= 1.5
Step-by-step explanation:
5 -2x+12 = 14
Combine like terms
17 -2x = 14
Subtract 17 from each side
17-17 -2x = 14 -17
-2x = -3
Divide by -2
-2x/-2 = -3/-2
x = 3/2
x= 1.5
