In 2007, approximately 50% of the world's population lived in rural (defined as non-urban) areas. From 2005 to 2013, the percent of the world's population living in rural areas decreased
by about 0.5 percentage points per year. If t represents years since 2005, which of the following
equations best models the percent of the world's population living in rural areas, r, from 2005 to
2013?

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
