You would do: 9+18+20=47-10=37
So your answer is 37
Answer:
Step-by-step explanation:
As the center of dilation is A, it does not change.
As A is the origin, B is (12, 4)
So B' will be (12/4, 4/4) = (3, 1)
Or from A move 3 right and 1 up
As A is the origin, C is (8, - 8)
So C' will be (8/4, -8/4) = (2, -2)
Or from A move 2 right and 2 down.
X +y=13
1/2*x+y=10 |-1
x +y=13
-1/2*x-y=- 10 } +
x-1/2*x=13-10
1/2*x=3
x=3*2
x=6
6+y=13
y=13-6
y=7
The solution is : (6,7)
A+b=13
a-b=7
add the two equations using system of equations
2a=20
a=10
10+b=13
b=3
