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
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:
1: 0.625, 2: 1.05, 3: 2 13/20
Step-by-step explanation:
Use a calculator to determine the exact value of the fractions, or do it by hand.
Answer:
0.625 , 1.05, 2 13/20
Step-by-step explanation:
Well, this isn't that hard if you really think about it.
For Number 1: 5/8 as a decimal, first you want to divide
100 by 8, which equals to 12.5. Then multiply 12.5 by 5 which gets you 62.5
Move the decimal place 2 to the left, and you get 0.0625.
For Number 2: 1 and 1/20
100/20=5
So you have 1 and 5/100, convert 5 to percent so 5%
5%+100%=105%
105= 1.05
Number 3: 2.65
100/20=5
13x5=65
0.65+2= 2.65, 2 13/20.
0.1 x 0.01 x 0.001

(a) Show that f^-1(50) = 3
Answer:
hope it helps you.....
and I m feeling bad for my handwriting
The proof of the value of the inverse equation f^-1(50) = 3 is below
How to prove the value of the inverse equationFrom the question, we have the following parameters that can be used in our computation:
f(x) = 2x^3 - 4
To show that f^-1(50) = 3, we simply show that
f(3) = 50
substitute the known values in the above equation, so, we have the following representation
f(3) = 2 * 3^3 - 4
Evaluate
f(3) = 50
Hence, the proof of the value of the inverse equation is done

Sarah took a 20? Test and got 17 problems correct what percent did she get
Answer:
85%
Step-by-step explanation:
Divide the number of problems gotten right by the total number of problems.
Sarah got an 85%.
Use this method.
part/whole = %/100
So.
17/20 = x/100
Cross multiply.
17•100=1700
20•x=20x
Divide by 20
1700÷20=85
Therefore the answer is 85%

help me no link dummys jk A venue is preparing for a concert on the floor shown.The width of the red carpet is 1/6 of the width of the floor.What is the area of the red carpet
Answer:
The area of the red carpet is 1057 ft²
Step-by-step explanation:
The area of the red carpet is 112.35 ft².
Given that, the width of the stage =63 ft and the length of the stage =10 2/3 ft.
What is the area of a rectangle?The area of a rectangle is obtained by multiplying its length and width. Thus, the formula for the area, 'A' of a rectangle whose length and width are 'l' and 'w' respectively is the product "l × w".
Now, the width of the red carpet is 1/6 of the width of the floor = (1/6) × 63
=10.5 ft
Here, 10 2/3 can be written as 10.66 ≈ 10.7 ft
The area of the red carpet = length × width = 10.7 × 10.5
=112.35 ft²
Therefore, the area of the red carpet is 112.35 ft².

1. If a whole number is a multiple of two, then the whole number is even.
2. Rabbits are animals that eat carrots.
3.Two lines that intersect to form four 90 degree angles are perpendicular.
4. Mammals are warm blooded animals.
Answer: 1. not revisable
2. not revisable
3. Not reversible
4. not revisable
Step-by-step explanation: 1.Likewise, a number is a reversible multiple if the number formed by 2058 is not reversible because 8502/2058 = 4.131, which is not a whole number
2. When rabbits eat carrots you cannot form the carrot back to its original form so that's why its irreversible (not/non revisable)
3.If two perpendicular lines intersect, they form four 90* angles. ... whose sum measures to 90 degrees - The statement is not reversible
4. a few species of cold-blooded mammals exist but you cannot change a warm blooded animal into cold.

1. Optiond D is correct, Triangle proportionality theorem can be used to find a missing length in a right triangle.
2. Option D is correct, the value of x is 6.
1. The Triangle proportionality theorem can be used to find a missing length in a right triangle.
The triangle proportionality theorem states that if a line parallel to one side of a triangle intersects the other two sides at different points, then it divides the remaining two sides proportionally.
2. By triangle proportionality theorem:

Answer → x = 96° (degree)
Answer:

Step-by-step explanation:
If we look at the problem, we know that due to the fact that they are adjacent that they MUST be equal.
Here is the proof:
We'll assign each angle a letter as following
A B C D with A being the top left and D being the bottom right!
Now that we know that, first off, A has to be equal to 180-96 due to them being Supplementary Angles.
Therefore, A is 84 degrees.
Now to find x, we can use Supplementary Angles again.
x has to be 180-84 which is 96 degrees proving the theorum.
