Question1: A piston moves up and down in a cylinder. In this simulation, it takes 3 seconds for the
piston to complete one cycle. If the low position of the piston is y = 2 cm and the high
position of the piston is y = 22 cm. Which function would be used to model this situation?
a, y = 10 sin42 + 12
C. y = 12 sine + 10
b. y 10 sint + 12
d. y = 12 sin + 10

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14
