The derivative of

is positive for all real numbers, which means the function is increasing in its all domain and therefore there is only one intersection with the x-axis ⇒ one solution.
Answer:
The population growth rate is of 1.86%.
Step-by-step explanation:
Population growth rate:
Immigration plus births subtracted by emigration and deaths.
In this question, we have that:
Birth: 14.3 per 1000
Death: 11.8 per 1000
Immigrations: 21.6 per 1000
Emigrations: 5.5 per 1000
Rate:

As a percentage:
Multiply by 100%. So
0.0186*100% = 1.86%
The population growth rate is of 1.86%.
Answer:
linear equation for 2y+10x=60 is y=-5x+30 .. the other one is invalid
Step-by-step explanation:
Answer:
Option A is correct.
The missing justification is: Transitive property
Step-by-step explanation:
Given:
, 
Symmetric property of equality states the if for all real values of x , y
if x =y then, y =x.
Then, by symmetric property of equality:
we can write
as
Transitive property of equality states that if we have the two things that are equal to each other and the second thing is equal to a third thing.
i.e, if a =b and b =c
then a =c
By transitive property of equality:
if
and
then;
......[1]
Congruent angle states that the angles have exact the same measure
Therefore, by definition of congruent angles in [1] we have;

We are asked to find the slope of this graph; we are provided with two points:



- What we need in order to find the slope are two points and the slope formula.
Here's the formula:

Where
y2 and y1 are y-coordinates
x2 and x1 are x-coordinates
Substitute the values:

Simplify!
