The rental rate for a power washer has a one time fee of $60 plus $20 for each day of the rental. The graph shows the points representing the total cost of the rental. 150 (4,140) 125 Total Cost 100 (2,100) 75 50 25 1 2 3 Days Write an equation, in slope-intercept formly = mx + b) that models the total cost of the rental over time.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

answer: you need to organize this better it does not make sense.
