3.angleB is congruent to angle F 
4. The slope is -3 and the yintercept is 4
        
             
        
        
        
You are asked to find the missing value in
... 40 + ? = 70
given that it is also the solution to 
... ? + 5 = 35
Either way, you subtract the constant that is on the same side of the equation as the unknown.
... 40 + ? - 40 = 70 - 40
... ? = 30 . . . . the missing value
_____
You can check to see if this also satisfies the equation
... 30 + 5 = 35 . . . . . . . true
 
        
             
        
        
        
8,-2. place the x as 8 and y as -2.
 
        
        
        
Answer:
Distance = 5 
Step-by-step explanation:
D= sqrt (x1-x2)^2 + (y1-y2)^2
(5-2)^2 + (8-4)^2=3^2 + 4 ^2 = 9 +16 = 25
Sqrt of 25 = 5
Distance = 5 
Hope this helps
