Tony and Ricky spend a certain amount of money from their accounts each week at a pet shelter.

The table shows the relationship between the amount of money (y) remaining in Tony's account and the number of weeks (x):

Function 1:


Number of Weeks
(x) Amount Remaining (dollars)
(y)
1 30
2 24
3 18
4 12


The equation shows the relationship between the amount of money, y, remaining in Ricky's account and the number of weeks, x:

Function 2:

y = –7x + 30

Which statement states and explains which function shows a greater rate of change?
Function 1, because Tony spends $6 each week and Ricky spends –$7 each week
Function 2, because Ricky spends $7 each week and Tony spends $6 each week
Function 1, because Tony spends $18 each week and Ricky spends $23 each week
Function 2, because Ricky spends $30 each week and Tony spends $18 each week

Answers

Answer 1

Answer:

Function 2, because Ricky spends $7 each week and Tony spends $6 each week

Step-by-step explanation:

You find the rate of weekly rate of change by calculating the difference of the amount changing each week:

24 - 30 = - 6

18 - 24  = - 6

12 - 18 = - 6

As you see the rate of change is constant: - 6 dollars per week. This means that Tony is spending 6 dollars every week

Function 2: y = –7x + 30  

The rate of change is the slope (m) of the linear function, and this is the coefficient of the independent variable, x.

This equation is written in slope intercept form (y= mx+b)

Then the rate of change is - 7 dollar per week. This means Ricky spends 7 dollars every week.

Now you know that the two rates are constant and that the second function shows a steeper decreasing.

Answer:

Step-by-step explanation:

the leading degree(the biggest power in the function) x^4 and the leading coefficient is the number next to the highest power which is -5

so the answer should be

-5,4,x -> infinity, f(x) -> -infinity ; x -> -infinity, f(x) -> -infinity    

when you get asked questions like this look for the biggest power and the number next to it. if the power is even x will always be positive if its odd x can be either positive or negative it depends on restrictions.

for instance in this example -5 * x^4 will always give you negative because -5 will multiply with a positive number x (the power is even so its always positive)

Tonis cat weighs 2,240 grams. How many kilograms does her cat weigh? Use 100 grams = 1 kilograms to convert the rates.

Answers

Answer: 2.24

Step-by-step explanation:

Firstly, one kilo is 1000 grams, not 100. 2240/1000=2.24

Toni's cat weighs 22.4 kilograms.

To convert grams to kilograms, we divide the weight in grams by the conversion rate of 100 grams per 1 kilogram.

For Toni's cat weighing 2,240 grams, we divide 2,240 by 100 to get the weight in kilograms.

2,240 grams / 100 grams per kilogram = 22.4 kilograms.

Therefore, Toni's cat weighs 22.4 kilograms.

The conversion rate of 100 grams to 1 kilogram allows us to easily convert weights from smaller units (grams) to larger units (kilograms). In this case, dividing the weight in grams by 100 gives us the weight in kilograms, providing a simple way to convert between the two units.

Answers

Answer:

The answer is 100.

Step-by-step explanation:

I started with solving 4 divided by 5. It was 0.8. I then started going thru 1 to 10 to 20 to 50 to 100. I was comparing big numbers. I then realized 100+0.8 times 100 = 180!

Answer: [tex]x=100[/tex]

If the equation is [tex]x+\frac45 x = 180[/tex] we add on the LHS: [tex]x(1+\frac45) = 180 \rightarrow x(\frac55+\frac45)= 180\\\frac95 x = 180[/tex]

At this point we divide both sides by 9 and multiply by 5:

[tex]x=\frac 59 (180) = \frac59 (2\times 9 \times 10) = 100[/tex]
