Write three statements that are true about this situation. Use function notation. Function “F” gives the distance of a dog from a post, in feet, as a function of time, “t”, in seconds, since its owner left.

Use the = sign in at least one statement and the < sign in another statement.

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
