Well what is the problem ?
Answer:
May be b is the answer...
Answer:
the first selection (see below)
Step-by-step explanation:
The average rate of change (m) on the interval [x1, x2] is given by ...
... m = (g(x2) -g(x1))/(x2 -x1)
For g(x) = -x²-4x and (x1, x2) = (6, 8), the expression is the one attached.
-1/5 * n ≤ 17
n ≥ -17/5 is the answer
The answer is A) 45°. This is because angles 1 and 5 are vertical angles. Vertical angles are congruent.
