Answer: The rule (x,y)=(y,-x) describes the
transformation
Step-by-step explanation:.........bc
Answer:

Step-by-step explanation:
i)
C - 11 /9 = 9
Multiply both sides by 9
c - 11 = 81
add 11 to each side to isolate c
c = 81 + 11 = 92
Answer:
7 and 9 are alternate interior angles
Step-by-step explanation:
4 and 11 are corresponding angles
1 and 7 are vertical angles
Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
