In 1995 town A had 500,000 people but this number had decreased to 425,000 by 2005. Town B had 320,000 people in 1995 and had grown to 380,000 by 2005. Assuming that both towns continue to grow at the same rate find linear models for both towns A and B.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
In 1995 town A had 500,000 people but this number had decreased to 425,000 by 2005. Town B had 320,000 people in 1995 and had grown to 380,000 by 2005. Assuming that both towns continue to grow at the same rate find linear models for both towns A and B.
Given
The population of town A
In 1995 - 500,000
in 2005 - 425,000
The population of town B
In 1995 - 320,000
In 2005 - 380,000
Also given to assume that the two towns continue to grow at the same rate
Then find a linear model for the two towns
