Answer:
11
Step-by-step explanation:
11 + 10 = 21
Last one: Use employee identification numbers to randomly select 200 employees.
It's the most random.
(-3, -2) is the vertex.
You can find this by plugging into -b/2a to find the x value and using the x value to find the y value.
And another spot on the vertex would be (0, 16), which is the y intercept.
