Given the rule write 1 if the input is odd; write 0 if the input is even; give the output for the following inputs: -3,-2. -1, 0, 1, 2, 3. *

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

the answer is b.)

< 1=< 2

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
