Help please!!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. (5 points)

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

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. (3 points)

Answer: x ≤ 5 or x > 7

Step-by-step explanation:

First, we will write an equation for the left side. It's a closed dot going to the left (less than) of 5.

x ≤ 5

Next, we will write the right side. It's an open dot going to the right (greater than) of 7.

x > 7

Lastly, we will combine these to create our compound inequality.

x ≤ 5 or x > 7

Answer:

-infinity less than or equal to 5 and 7 less than infinity

Tickets to a play cost $5 for adults and $2 for children. If 1,750 tickets were sold for a total of $7,100, how many children’s tickets were sold?Can someone explain me how to make this one step by step?

Answers

okay so you have 1750 tickets and 7100 dollars so you gotta do
7100 divided by 5 wich gives you the amount of adult tickets which is 1420 you then have to take 1420 away from 1750 which leaves you with 330

Label adults ticket x and child's ticket y
And then use simultaneous equations

Write 6y = x + 5 in standard form using integers. A. –x + 6y = 5
B. –6x + 6y = 30
C. -6x - 6y = 30
D. 6x - 6y = 30

Answers

I hope this helps you

-x+6y=5

Standard form is Ax+By=C, so with that knowledge, we can work with the problem to get it how we want it!

Our first step is to get x and y on the same side of the equals sign. To do that, we can subtract an x from both sides, turning 6y = x + 5 into -x +6y = 5. Lucky for us, this brings us straight to the answer, which is A) -x +6y = 5!
