Answer: 4 5/6
Step-by-step explanation: 4 5/6+ 1 3/6(aka 1 1/2)= 6 2/6 (aka 6 1/3)
This works because she added the number to she if she got right
<span>The mixed number -4 1/5 can be written as the improper fraction -19/15
It's false
</span>- 4 1/5 = - (20/5 + 1/5) = -21/5
Hope it helps
Answer:
The second answer is the right one
Step-by-step explanation:
Let a be the average rate of change in the interval [0,4] for the function A
● a = (16-0)/(4-0) = 16/4 = 4
The average rate of change in [0,4] is 4 for the function A
Let b be the averagerate of change in [0,4] for the function B
● f(4) = 2×4-1 = 8-1 = 7
● f(0) = 2×0 -1 = -1
● b = (f(4)-f(0))/(4-0)= (7-(-1))/4 = 8/4 = 2
So the average rate of change in[0,4] is 2 for the function B
