If δabc is dilated by a scale factor of 2 with a dilation center of a, what will be the coordinates of point b'?

additional info:
a(0,0) b(0,3) c(2,0)

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
