Answer:5
Step-by-step explanation:
<h3><u>(8 + 2)</u> <u>sum of values  </u>    =    <u>10</u>  =  5</h3><h3>    2    number of values        2</h3><h3 />
There is equal spacing between the mean and the extremes
8 - 5 = 3
5 - 2 = 3
 
        
             
        
        
        
X = 7
y = 10
x + y = 700
7x + 10y = 6400
 10x + 10y = 7000
(-) 7x + 10y = 6400
 ______________
 3x = 600
 x = 200
200 + y = 700
y = 500
        
             
        
        
        
21-3= 18 and 18 divided by 6 equals 3 so v=3
        
             
        
        
        
x = -1
y = 1
To find this, input the equation into a graphing calculator, whether online or an actual one, and you have two options:
1 - Search for the points in which the line crosses the x and or y axis.
2 - Hit 2nd Graph to access the table and find when x and y equal zero.
Hope this helps!
