Answer:
10 miles per 1 minute
Step-by-step explanation:
100 miles / 10 minutes
100/10
10/1 
10 miles / 1 minute
 
        
                    
             
        
        
        
The answer should be $21,840.50
Explanation:
20000*1.045=a (first year)
a*1.045=b (second year)
b = 21840.5
        
             
        
        
        
Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values. 
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.
 
        
        
        
Answer:
10 mins
Explanation:
Because it takes 2 minutes to fill a 30 gal pool, and 150/30=5, 2 x 5 = 10 giving you the answer of 10 mins to fill a 150 gal pool.
 
        
             
        
        
        
Answer:
x = 20
Step-by-step explanation:
Solve for  x  by simplifying both sides of the equation, then isolating the variable.
