Answer:
True.
Step-by-step explanation:
The explicit form for an arithmetic sequence is:

where
is the first term and
is the common difference.
The common difference here is 2 because the y's are going up by 2 while the x's are going up by 1.
Yes, the common difference is the slope.
So we have d=2.
The first term is 9.5 because that is what happens when x=1.
x is n.
y is
.
So the answer is true.

You can also verify by plugging in numbers for n and see if you get the outputs mentioned in the pairs given:
Let n=1:




Let n=2:




Let n=3:




Let n=4:




Let n=5:




Let n=6:




We have confirmed that we get all 6 of the mentioned points using the equation they gave.
Answer: yes

Add subtraction multiplication and division
Answer:
I think it is G
Step-by-step explanation:
So ya see, it really does peak at the given times.
2+(-3) = -1
2- 3 = -1
-1=-1
The question is why though ?
It is because you keep the negative exponent which is with the biggest number. So this is how its look like +2 -3, so 3 is bigger then 2 so for that reason you keep the negative sign.
I hope that's help:)
