Answer:
y ≤ +
.
Step-by-step explanation:
Given : Graph .
To find : Which linear inequality is represented by the graph.
Solution : We have given graph with shaded down and solid line
It has solid line it mean inequality has equal to sign.
It is shaded down it mean inequality y has less than or equal to sign.
Slope = .
Slope = .
Slope = .
Y intercept = 0.2 = .
y intercept = .
Equation of line y = mx + b
Where m = slope , b = y intercept .
Plug the values of slope and y intercept .
y ≤ +
.
Therefore, y ≤ +

Answer:
At the start of 2014, the population was growing at 8.34 million people per year.
At the start of 2015, the population was growing at 8.39 million people per year.
Step-by-step explanation:
To find how fast was the population growing at the start of 2014 and at the start of 2015 we need to take the derivative of the function with respect to t.
The derivative shows by how much the function (the population, in this case) is changing when the variable you're deriving with respect to (time) increases one unit (one year).
We know that the population, P(t), of China, in billions, can be approximated by
To find the derivative you need to:
To find the population growing at the start of 2014 we say t = 0
To find the population growing at the start of 2015 we say t = 1
To convert billion to million you multiple by 1000
