Answer: G = 2E + 3
<u>Step-by-step explanation:</u>
Let E represent Elena's age.
Then Gary(G) is two times Elena(E) plus 3 --> G = 2E + 3
 
        
             
        
        
        
Answer:
100 
Step-by-step explanation:
The population is changing linearly. This means that the population is increasing by a particular value n every year.
From 2009 to 2017, there are 8 increases and so, the population increases by 8n.
The population increased from 1700 to 2500. Therefore, the population increase is:
2500 - 1700 = 800
This implies that:
8n = 800
=> n = 800/8 = 100 
The average population growth per year is 100.
 
        
             
        
        
        
Answer: 4.5
<u>Step-by-step explanation:</u>
First, find the points of intersection by solving the system.
y = x² + 2x + 4
y = x + 6
Solve by substitution:
x² + 2x + 4 = x + 6   ⇒   x² + x - 2 = 0   ⇒   (x + 2)(x - 1) = 0   ⇒   x = -2, x = 1
Now, integrate from x = -2 to x = 1
 <em>the bottom of the integral is -2 </em>
    <em>the bottom of the integral is -2 </em>
=  
 
=  
  
= 
= 
= 
= 
= -3 + 1.5 + 6
= 4.5
