Answer:
4
Step-by-step explanation:
-2x- 4 + 5x = 8
Collect like terms
-2x + 5x = 8 +4( when a variable crosses over equality sign it becomes either negative or positive depending on the sign)
3x = 12
Divide via by coefficient of x
X = 12/3
= 4
Answer:
r = 

Is this a live test question or a homework question?
Step-by-step explanation:
the radius is the distance between (3, 2) and (5, -2)
= 
= 
= 4 + 16 = 20
r = 
Equation of circle: 

The final result is: C) x(x - 8)(x + 8).
In a direct proportion, the equation can be set up as
y = kx
k = y/x
k = 6/20
k = 0.3
