Answer: 35.3
Explanation: (-3-2-1+0+1+2+....27)/30 = 35.3
        
             
        
        
        
225 miles / 45 miles/hr = 5hr
        
             
        
        
        
Answer:
d = 56x + 412
Step-by-step explanation:
To find the total number of miles traveled on Monday and Tuesday, use a linear equation to write the function.
y = mx+b where m is the speed or rate of change and b is the starting point.
The starting point on Tuesday is 412 miles. This is b. 
The number of miles traveled on Tuesday is found by calculating 56 miles times the number of hours traveled.  This is the slope or m.
So the equation is d = 56h + 412.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
hg(x) means you multiply h(x) times g(x) and then we will set it equal to  .
. 
hg(x) =  which simplifies to
 which simplifies to

Answer:

Step-by-step explanation:
To find slope using two points you need to find the difference in x and y. You use 
So, 2-0=2 and 5-(-4)=9. Therefore the slope is 2/9x
