Answer:
hi there the correct answer is b
Step-by-step explanation:
A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs.
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A.
Part C: If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values.
Will mark Brainlist!!!
Answers
Answer: PART A.
y= remaining height of candle
x= rate the candle burns down in inches per hour
8= original height of candle
the function would be y=8- 0.5x because the candle starts at a height of 8 feet and loses half an inch per hour.
You can use this function to create ordered pairs by putting in number at x which indicates the time:
x=1
y=8- (.5×1)= 7.5
(1, 7.5)
you can then do this for other numbers and get:
(2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)
PART B.
This equation is a function because all of the x-values had different y-values as seen in the coordinates (1, 7.5) (2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)
PART C.
If the rate was 0.4 inches an hour, it would still be a function because the rate is the only thing that changed making the new function y= 8- 0.4x.This equation would make coordinates of (0,8) (1, 7.6) (2, 7.2) (3, 6.8) and so on with each x value creating a different y value.

Is it possible to write a polynomial of degree 3 with zeros at 5, 3 and 8i? Explain your reasoning.
Answers
Answer:
No
Step-by-step explanation:
Because if 8i is a zero then -8i is also a zero. That means you now have four zeros, so the function is at least a fourth degree (quartic) function.
It is not possible to write a polynomial of degree 3 with zeros 5, 3 and 8i.
What is degree of polynomial?
A polynomial’s degree is the highest or the greatest power of a variable in a polynomial equation.
The degree of a polynomial is equal to the real zeros of the polynomial. Real zeros of the polynomial are 5 and 3 only. 8i is a complex number. Thus degree of the polynomial is 2.

Lin spends $3 on 7 markers and a $1 pen
Answers
Answer: Choice C and Choice D
========================================================
Explanation:
Choice A doesn't work because it the $1 should be $7 instead.Choice B doesn't work because it should be Elena spending $7 total on 3 notebooks and a $1 pen. The x is the amount per notebook.Choice C does work. If x is the number of grapes Noah gives each friend, then 3x is the total amount Noah gives over. Then 3x+1 is the number of grapes total. That +1 at the end is the grape Noah eats. We end up with 3x+1 = 7 because Noah starts off with 7 grapes.Choice D works also. The x is the number of hours for math, science and history each. So 3x is the combined time of those three classes. Add on 1 to get 3x+1 to represent all 7 hours, ie 3x+1 = 7.Choice E does not work. If it was her spending $7 on 3 markers and a $1 pen, then it would work.Answer:
[] Noah shares 7 grapes with 3 friends. He eats 1 and gives each friend the same number of grapes.
[] Andre studies 7 hours this week for end-of-year exams. He spends 1 hour on English and an equal number of hours each on math, science, and history.
Reasoning:
[✗] The first story, with Diego, does not work because the whole is $1 in the problem and $7 in the diagram.
[✗] The second story, with Elena, does not work because the 7 is ignored entirely and the x becomes a known value, 57.
[✓] The third story, with Noah, does work because he splits seven grapes equally among three friends (the x's) and eats one.
[✓] The fourth story, with Andre, does work because 7 hours were spent studying. One on English and the rest (three subjects) split evenly (x).
[✗] The fifth story, with Lin, does not work because the total is $3 when it should be 7.
