Answer:
4
Step-by-step explanation:
a+16=20
a=20-16
a=4
Use the points to find the equations of both your lines.
By using the formula for finding slope where: m = (y2-y1) / (x2-x1)
Your first equation is y = -2x+4
Your second equation is y = -2x+7
Normally you want to set these equal to each other and see where they are equal... however, as you can clearly see, these two equations are parallel. Parallel equations don't intersect, which would mean your answer is A, no solutions.

Answer:
Step-by-step explanation:
a) if the population at the beginning of the year 2000 was 7500 people,
The 1-year percent change in the city's population would be
3.6/100 × 7500 = 270
b) The population after 1 year is
7500 - 270 = 7230
The percentage of the previous value of the population to its new value for each year is
7230/7500 × 100 = 96.4%
c) the 1-year growth factor for the population of the city would be
(1 - 0.036)^1 = 0.964
d) the function, g that determines the population of the city (in thousands of people) in terms of the number of years t since the beginning of 2000 would be
g = 7500(1 - 0.036)^t
g = 7500(0.964)^t
