Which of the following represents the equation of the line that passes through the point (-2, 4) and is perpendicular to the line y = 2 3 x − 2?
A. 2x +3y = 8
B. 3x +2y = −2
C. 3x −2y = −14
D. 3x +2y = 2

Part A: Your composite function would be plugging in your s(w)=40w in for the s in f(s)=2s+30

Your expression would be

2(40w)+30

80w+30= your given expression

Part B: The units for the composite function in Part A would be:

number of flowers

Part C: You would plug 35 in for the w in our expression in part A

80*35+30

2,800+30

2,830
