The population of the world in 1987 was 5 billion and the Growth Rate per Decade was estimated at 21 percent per decade. Assuming that the world population follows an exponential growth model, find the projected world population in 1991.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m
