Answer:
51.6 was the average speed
Step-by-step explanation:
speed= distance/time
it 7{-2}= 9/1 and it equals to=9
Step-by-step explanation: 7{-2)= 9/1=9
The answer is 3x - 1
f’(x) = x -2/7
Let f(x)= y
Thus;
y = x + 2/7
x = y-2/7
So the inverse f’(x) = x - 2/7
57
0; one real roots
* the answer is C
