Hello! I would love to help!
Let's start by decreasing 32 pages to 28. How many pages does it take to get from 28 to 32? Let's subtract to find out!
32-28=4
Okay, now we know 28 pages is 4 less than 32.
Now, what percentage did it decrease by? Let's find out by dividing!
4/32=0.125
Let's make that decimal into a percentage by multiplying it by 100.
0.125*100=12.5
So, we now know the answer is...
decreased by 12.5%
Hope this helped! Comment if you have questions!
Answer:
x=0
Step-by-step explanation:
20=-5(4x-4)
-20/5 =4x-4
-4=4x-4
0=4x
0=x

3(y-2) + 2(y-2) = 5(y-2)
Both terms have the base (y-2), so they can be added together.
3 + 2 = 5
F(-4)= 9*3^(-4)=9/(3^4)=1/9
Given:
Population of a colony in 2000 = 250
Population of a colony in 2004 = 400
To find:
The average rate of change.
Solution:
Let y be the population of the colony at x year.
The population of a colony grows from 250 in the year 2000 to 400 in the year 2004. So, the two points are (2000,250) and (2004,400).
Formula for slope or average rate of change is
Therefore, the average rate of change of population is 37.5.
