Please answer it please

b) $0.50, it represents the price per mile to drive the rental van.

Step-by-step explanation:

Find the slope by taking 2 points from the graph: (20, 40) and (40, 50)

Use the formula to find the slope: y2 - y1/ x2 -x1

Substitute the values into the formula above:-

50 - 40 / 40 - 20

=> 10/20

Simplify

=> 1/2

=> 1/2 = 0.50

The slope is $0.50

hope this helps and is right. p.s. i really need brainliest :)

ok

step-by-step explanation:

hope it you

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
