Answer:
-1ab^2 + 5b + 8
Step-by-step explanation:
3a^2+9ab+5-4a^2-4ab+3
3a^2-4ab^2=-1ab^2
9ab-4ab=5ab
5+3=8
-1ab^2+5ab+8
Only 25 and 28 are functions.
A function must have only one y value per x value. For 26, the y value of 0 and multiple others have two different y values. For 27, all x values less than 0 have multiple y values.
I don’t know the rest, but I think the 1st and 3rd ones are true! I hope this helps some, I’m sorry if it’s incorrect!
Answer:
0.321 (Answer D)
Step-by-step explanation:
Note that the event "A and Y" happens 9 times. That's 9 times out of (6+9+8+5) outcomes, or 28 outcomes.
Hence, P(A and Y) = 9/28, or 0.321 (Answer D)
