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: 88
Step-by-step explanation: The equation us .8x=352 and 352/.8 is 440, which is the total. Multiply 440 by .2 which gives you 88
No.
The reason it's no is because y-x^2=9 is does not go through the the the y axis with a straight line. Instead, it goes through cricked. You have to have a better line to be able to have the yes option, if it was going straight through then it would be the correct answer.
Ahemmmm what is 3/8 of 48? well, is just their product.
