Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
 
        
                    
             
        
        
        
He will never reach the full foot, this is because if he travels 1/2 of the distance of the previous jump each time there will always be a fraction that is unaccounted for.
        
                    
             
        
        
        
Answer:
<em>The actual width of the hair is 20 / 150 = 0.13 mm</em>
Step-by-step explanation:
<u>Scaling</u>
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling in several applications of real-life.
The human hair is magnified 150 times by a micro-phtograph. This is the scale factor.
The hair can be seen 2 cm wide in the photograph.
Converting to millimeters, 2 cm = 2*10 = 20 millimeters.
The actual width of the hair is 20 / 150 = 0.13 mm
 
        
             
        
        
        
There’s no slope through (5,-4)
        
             
        
        
        
f(x) + g(x) = 5x - 3 - 2x + 7
                = 3x + 4
