Perpendicular = opposite sign and reciprocal slope 
Slope 2 turns into -1/2
Y = -1/2x + b
Plug in the point
-5 = -1/2(2) + b, b = -4
Solution: y = -1/2x - 4
        
             
        
        
        
Answer: 0.10d + 0.05n
Note: this value expression is in dollars (not cents)
If you want the expression in cents instead of dollars, then it would be 10d+5n
--------------------------------------------------------------------------------
The value of just the dimes only is 0.10d dollars
The value of just the nickels only is 0.05n dollars
Combined the total value is 0.10d+0.05n dollars
        
             
        
        
        
Answer:
1:10 pm 
Step-by-step explanation:
<em>60 minutes in an hour</em>, so 
8:50am + <u>4 hours</u> = 12:50pm 
12:50pm + <u>20 minutes</u> = 1:10pm
 
        
             
        
        
        
Answer:
The answer is A (Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate)
Step-by-step explanation:
Because the proportional relation is defined by k = 
. If ratio is 
 then it is a rate. Unit rate means per 1 unit such as 
 or 
 thus the correct answer is A.
