Its C.
Triangle A is straight up and down and then when you rotate it 90 degrees at point C,It becomes point B.
To solve this, you basically just look at what point it is rotated at, then figure out how far it is rotated.
Hope this helps :)
Answer:
(-11, - 9)
Step-by-step explanation:
Given the 2 equations
a - 3b = 16 → (1)
a = b - 2 → (2)
Substitute a = b - 2 into (1)
b - 2 - 3b = 16
- 2b - 2 = 16 ( add 2 to both sides )
- 2b = 18 ( divide both sides by - 2 )
b = - 9
Substitute b = - 9 into (2) for the corresponding value of a
a = - 9 - 2 = - 11
Solution is (- 11, - 9)
