Answer:</h2><h2>
The population of the city after 7 years = 569,859</h2>
Step-by-step explanation:
The population of the city of Miami = 463,300
The rate of increase in population every year = 3%
The population of the city after 7 years = ?
By formula, 
Pn is the population after 7 years
P is the current population = 463,300
r = 3 %, n = 7

= 463300 (1.23)
= 569859
The population of the city after 7 years = 569,859
1. 5/y=2/3x +3
2. y= 7/1-4
3. y=2/5x8
4. y=-3/4 +1 I could be wrong but I think this is right
