Answer:
Substitute in the values of both given coordinates & form 2 equations:
Find the value of B from the equation 2A - B = 1:
Substitute in the B-value to the other equation:
Find the B-value using the equation from before:
Therefore the equation Ax + By = 1 would equal:
percent of increase for a population that changed from 25,000 to 30,000
Increase in population = 30,000 - 25,000 = 5000
So, the increase in population is 5000
To find percent of increase , we divide the increase in population by initial population.
So percent of increase = * 100
= 0.2 * 100
= 20 %
20% of increase for a population that changed from 25,000 to 30,000.
