-9/1*4/3=-36/3
-36/3 is known as -12. The answer is -12.
(9x-2) - (5x+6) =
4x-8 , this is your profit function
BCD= 120 degrees. explanation: the 4 angles of a parallelogram must equal 360 degrees. so you add all 4 angles & get 6x. you then take that 6 & divide it from 360 (360/6) and get 60. therefore x=60. so then you just multiple BCD (2x) by 60 and you get 120 degrees
To make both sides of the equations equal and balanced.
The fixed amount is 6 because it's 6 dollars for 0 miles traveled.
