Answer:
A. (−3,5)
Step-by-step explanation:
The rule for dilation by scale factor k is given by:

The given point is P(-3,5) and the scale factor is k=1
We substitute the point and the scale factor into the rule to get:

This gives us:

The correct answer is A

Answer:
x = 21.8°
Step-by-step explanation:
tan = opposite / adjacent
tan x = 8/20
tan^-1 = 21.8°
D = sqrt((0-18)^2 + (-5--10)^2)
D= sqrt ((-18)^2 + (5)^2)
D= sqrt( 324 + 25)
D= sqrt ( 349)
D = 18.7
