Divide -4 on both sides then change the greater then sign to less then so it looks like....-x < -3
3.5(c-8)+c = 12.5
⇒ 3.5c- 3.5*8+ c= 12.5 (distributive property)
⇒ (3.5c+ c) -28= 12.5
⇒ 4.5c= 12.5+ 28
⇒ 4.5c= 40.5
⇒ c= 40.5/ 4.5
⇒ c= 9
The correct answer is 9~

Step-by-step explanation:
Part A If the polygon is above the line, the rotation angle is 180+a.
If the polygon is below the line, the rotation is a.
Part B Rotations may be clockwise or counterclockwise. When working in the coordinate plane: assume the center of rotation to be the origin unless told otherwise. assume a positive angle of rotation turns the figure counterclockwise, and a negative angle turns the figure
