1 At the end of 2016 the population of a city was 200 000. At the end of 2018 the
population was 264 500.
a Assuming that these end of year figures
follow a geometric sequence, find the
population at the end of 2017.
b Calculate the population at the end of
2020.
c Comment on whether this increase
will continue. Give a reason for your
answer.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
