Answer:
13.5
Explanation:
The equation to find the slope (another word for the rate of change) of the line is (y2-y1)/(x2-x1) when the given points are (x1,y1) and (x2,y2).
When we plug in the given points, (3,-7) and (5,20) we can start solving.
(y2-y1)/(x2-x1)
(20-(-7))/(5-3)
Two negatives make a positive
= (20+7)/(5-3)
= 27/2
= 13.5
I hope this helps!
Answer:
Step-by-step explanation:
Let the amount of the job is x.
You can do 1/2x in an hour.
Your friend can do 1/3x in an hour.
<u>Together you can do:</u>
- 1/2x + 1/3x = 5/6x of a job in an hour
<u>You need time to finish the job:</u>
- x ÷ 5/6x = 6/5 = 1.2 hours

Answer: 4
Step-by-step explanation:
The given function :
The average rate of change in a function g(x) from x=a to x=b is given by :-
Then, the average rate of change of the given function from x = 1 to x = 3 will be :-
x = 1 to x = 3 is 4
Answer:
9
Step-by-step explanation:
It saying 3 times to the power of 2
or
3 squared
so basically it's saying
3^3=9
