Answer:
-9/20 with the given information i believe this is the answer
Over 3 up 6, or better know as 3/6
Answer:
the correct answer is b (4,2)
Answer: -89
Step-by-step explanation:
So your equation is
- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)
You know that (a) (b) and (c) = -1
You also know that (x) and (y) = 7
So, when you put this into the equation, it will look like this:
- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)
When you work that out you will get left with your answer, which is -89.
HOPE THIS HELPS!!!
