Answer: The sequence rule is division. 80 divided by 2 = 40 divided by 2 = 20 divided by 2 = 10 and 10 / 2 equals 5.
Step-by-step explanation:
The sequence is divided by 2 because when you divided 80 by 2, it equals the second pattern in the sequence, 40.
I worked it out by dividing every number by 2 and getting the same numbers in the pattern, I checked by doing the opposite, 40 x 2 = 80.
Hope this helps!

Answers:
- C) Factored form
- C) Standard form
- D) The y intercept is -8
- B) Two solutions: x = -5 or x = 5
- B) Apply square root to both sides
=========================================
Explanations:
- For problems 1 and 2, there's not much to say other than you'll just have to memorize those terms. Standard form is ax^2+bx+c in general. The exponents count down 2,1,0. Factored form is where we have two or more factors multiplying with each other. Think of something like 21 = 7*3 showing that 7 and 3 are factors of 21.
- For problem 3, the y intercept is the last value. It's the constant value. Plug in x = 0 and you'll get y = -8 as a result. The y intercept always occurs when x = 0.
- In problem 4, we apply the square root to both sides to get x = -5 or x = 5. The plus or minus is needed. This is because (-5)^2 = 25.
- In problem 5, we apply the square root to both sides to undo the squaring operation.
3X+9X=180

That's your answer.
Answer:
Step-by-step explanation:
On a grid,
go to the middle, aka 0,0
move left 4 times, but stay on the same line. Then draw that line up and down on the -4 of x.
