Answer:

The world population at the beginning of 2019 will be of 7.45 billion people.
Step-by-step explanation:
The world population can be modeled by the following equation.

In which Q(t) is the population in t years after 1980, in billions, Q(0) is the initial population and r is the growth rate.
The world population at the beginning of 1980 was 4.5 billion. Assuming that the population continued to grow at the rate of approximately 1.3%/year.
This means that 
So


What will the world population be at the beginning of 2019 ?
2019 - 1980 = 39. So this is Q(39).


The world population at the beginning of 2019 will be of 7.45 billion people.
Why are you asking me for help
The answer would be if you were solving for y. Y= 1/2x+3/8
You can add 14 to the 9 to get pith of the problem so you'd be left with |2x+1| = 23 then it comes it quite obvious that X=11 because 2 times 11 plus 1 equals 23
