D. If you ask the amount of projects completed using the computer lab you are asking a statistical question. Hope this helps!
Sin(θ - 180)
sin(θ)cos(180) - cos(θ)sin(180)
sin(θ)[-1] - cos(θ)[0]
-sin(θ) - 0
-sin(θ)
Answer:
5
Step-by-step explanation:
(4+11)/3 = 15/3 = 5
To be a function each different x value would have a different Y value.
First one is a function, there are no repeated Y values.
The second one is a function.
Third one is not a function because it has two identical Y values with different x values.
The fourth one is a function.
The equation would be 2x+3 so when you plug it in it's 2(-2)+3 which simplify to -4+3 which is -1
