The average rate of change between 1991 and 1996 is 40 million
<h3>How to determine the average rate of change between 1991 and 1996?</h3>
The given parameters are:
Population in 1991 = 1.5 billion
Population in 1996 = 1.7 billion
The average rate of change between 1991 and 1996 is calculated as:
Rate = (1.7 billion -1.5 billion)/(1996 - 1991)
Evaluate
Rate = 40 million
Hence, the average rate of change between 1991 and 1996 is 40 million

Answer:
4 x 20 - X
Step-by-step explanation:
4 times 20 - X
x is the unknown variable
Unknown variable = what you are trying to find.
You multiply 5 times 10, which gives you 50. This is the length of one side. Since it's a square, all sides are the same length.
Answer: 50cm x 50cm
The value of the function f(x) = x² + 6x - 9 when x = -5 is -14.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Given that:
f(x) = x² + 6x - 9
When x = -5:
f(-5) = (-5)² + 6(-5) - 9 = -14
The value of the function f(x) = x² + 6x - 9 when x = -5 is -14.
