Answer:
The 1st table represents a function
Step-by-step explanation:
Just trust me on this I took the quiz on edge 202 and got it right
the graph is
x     |     Y
--------------
-5   |  -22
--------------
0    |  -2
------------
3    |  10
 
        
             
        
        
        
Answer:
 $108
Step-by-step explanation:
1 box = $12
18 boxes = 12×18 = $216
Total = 18×65 = 1170 pens
Cost price, Cp = $216
3 = $1
378 = 378/3 = $126
1170-378= 792 pens remaining
4 = $1
792 = 792/4 = $198
Total selling price, sp = 126+198 = $324
Profit = Sp - Cp = 324 - 216 = $108
 
        
             
        
        
        
Answer:
The numbers are 39 and 14.
Step-by-step explanation:
Equation 1, sum of the numbers:
  
x  +  y   =  53
  
Equation 2, difference of the numbers:
  
x  -  y  = 25
  
System of equations:
  
x  +  y  =  53
x  -  y   =  25
----------------
2x = 78
  
x = 39
  
Solve for y:
  
39  +  y  = 53
  
y  =  14
  
The numbers are 39 and 14.

Answer:
-13
Step-by-step explanation:
Given that:
Average temperature for a period of 4 days = - 8
Average temperature for a 5 day period = - 9
Temperature on the 5th day:
(total temp for the 4 days + 5th day temperature) / 5 = - 9
Let 5th day temperature = x
Total temperature for the 4 days = 4 * - 8 = - 32
(-32 + x) / 5 = - 9
-32 + x = - 45
x = - 45 + 32 
x = - 13
