2:1 because it decreases my half which is the same as saying 2/1

Answer: C) 60</h3>
Explanation:
There are n = 6 sides in a regular hexagon, so each exterior angle is E = 360/n = 360/6 = 60
The rule E = 360/n only works for regular polygons with n sides, which means the polygons must have all sides the same length and all angles the same value.
Answer: x = -8
Step-by-step explanation:
Move all terms that don't contain x to the right side and then solve
Answer:
x = 9
Step-by-step explanation:
10x - 8 = 82
+ 8 + 8
10x = 90
/ 10 / 10
x = 9
Answer:
The inverse of the function is ±sqrt( (x+4)/2
Step-by-step explanation:
Set the function equal to y
y = 2x^2 -4
Exchange x and y
x = 2y^2 -4
Solve for y
Add 4 to each side
x+4 = 2y^2 -4+4
x+4 = 2y^2
Divide each side by 2
(x+4)/2 = 2/2y^2
(x+4)/2 = y^2
Take the square root of each side
±sqrt( (x+4)/2 )= sqrt(y^2)
±sqrt( (x+4)/2 )= y
The inverse of the function is ±sqrt( (x+4)/2
