Answer:
x > -12
Step-by-step explanation:
To "solve" this inequality (not question), we subtract 3 from both sides of 3+x>-9, obtaining
 x > -9 - 3, or x > -12.
 
        
             
        
        
        
It would take 36 minutes. If you use unit rate, you would take 20min/5people and see how many minutes does it take to paint one wall. Which would be represented by 4min/1person. To find how many minutes it would take for 9 walls, you get 4min/1person to become 9 people for the denominator. Then, whatever you do to the denominator you do to the numerator. So, 4 times 9 is 36. Therefore, making the answer 36minutes/9people.

2x² - 3x + 2 is the answer
        
                    
             
        
        
        
amplitude: 2
period: 2pi 
The equation for a sin function is:

a = the amplitude 
b = the period 
c = the horizontal shift
d = the vertical shift 
the equation to find the period of a sin function is:

note: the amplitude is always a positive number, if there is a negative sign in front of it then that means it reflects over the x-axis.
