Final answer:
In the expression 5x – 8(3y + 13) – 1: 5 is the coefficient of the first term, (3y+13) is a binomial, and –1 is the constant term.
Explanation:
The expression provided is 5x– 8(3y + 13) – 1, and we need to identify the roles of specific parts of each term:
In the first term, 5 is a coefficient; it is the numerical factor that multiplies the variable x.In the second term, (3y+ 13) is a binomial being multiplied by –8, which is a negative coefficient.In the third term, –1 is a constant term because it does not contain any variables and is a fixed value.In the first term, 5 is a coefficient.
In the second term, (3y+13) is a binomial.
In the third term, -1 is a constant.
To complete the statements for the given expression 5x – 8(3y + 13) – 1, we need to identify the components of each term:
1. In the first term:
Here, 5 is a coefficient because it is the numerical factor that multiplies the variable x. Coefficients indicate the quantity by which a variable is multiplied.
2. In the second term:
In this term, (3y+13) is enclosed within parentheses, making it a binomial. A binomial is an algebraic expression consisting of two terms separated by either a plus or a minus sign.
3. In the third term:
This term is a constant because it is a fixed numerical value that does not change. Constants can exist independently and do not involve any variables.
Complete question:
Use the given expression to complete the statements.
5x– 8(3y + 13) – 1
In the first term, 5 is a ____.
In the second term, (3y+ 13) is a ___.

The redwood national park is home to some of the largest trees in the world. Hyperion is the tallest tree in the park, with a height of approximately 379 feet. Tom wants to find the height of the tree in yards
Final answer:
To find the height of the tree in yards, divide the height in feet by 3, the conversion factor from feet to yards.
Explanation:
The Redwood National Park is home to some of the largest trees in the world, including Hyperion, the tallest tree in the park at approximately 379 feet. To find the height of the tree in yards, we can convert the height from feet to yards by using the conversion factor of 1 yard = 3 feet.
Height in yards = Height in feet / Conversion factor
Height in yards = 379 feet / 3 feet/yard
Height in yards = 126.33 yards
Therefore, the height of Hyperion is approximately 126.33 yards.

there are 56 fish in a tank and each fish is yellow blue or black.
There are six more yellow fish than blue fish, and 4 fewer blackfish than blue fish.
How many blue fish are in the tank.
A) 18
B) 22
C) 20
D) 27
Answer:
c?
Step-by-step explanation:
To find the number of blue fish, we set up an equation based on the given information, solving which indicates there are 18 blue fish in the tank (option A).
Explanation:The question is a word problem asking to find out the number of blue fish in a tank given the total number of fish and the relationships between the counts of different colored fish. We can set up algebraic expressions to solve for the number of blue fish. Let the number of blue fish be represented by x. According to the problem, there are six more yellow fish than blue, which we can express as x + 6. There are four fewer black fish than blue, which we can say is x - 4. The total number of fish is given as 56.
So, the equation we can set up is:
x + (x + 6) + (x - 4) = 56
Simplifying the equation, we get:
3x + 2 = 56
Solving for x, we subtract 2 from both sides to get:
3x = 54
And then divide by 3:
x = 18
Thus, there are 18 blue fish in the tank, which corresponds to option A.

1. A supermarket display consists of boxes of soda. The bottom row has 38 boxes. Each row has four fewer boxes than the row below it. The display has eight rows.
a) Write and use the function to determine how many boxes are in the top row. Show your work.
b) Use the appropriate formula to determine the number of boxes in the entire display. Show your work.
Answer:
10 boxes in the top row.
192 boxes in entire display.
Step-by-step explanation:
Let n be the number of rows.
Given:
Total number of rows = 8
Boxes in bottom row = 38
And each row has four fewer boxes than the row below it.
Solution:
Part A:
We know that the bottom row has 38 boxes and each row has four fewer boxes than the row below it.
Using below function for determining the number of boxes in each rows.
[tex]f(n)=38-(8-n)4[/tex]
Where:
n = Number of row.
We need to find the boxes in the first row.
So, substitute n = 1 in above function.
[tex]f(1)=38-(8-1)4[/tex]
[tex]f(1)=38-7\times 4[/tex]
[tex]f(1)=38-28[/tex]
[tex]f(1)=10[/tex]
Therefore, 10 boxes in the top row.
Part B:
Total boxes in the entire display.
Using formula as given below to determine the sum of the boxes in entire display.
[tex]S_{n} = \frac{n}{2}(f(1)+f(n))[/tex]
Substitute n = 8, f(1) = 10 and f(8) = 38 in the above equation.
[tex]S_{8} = \frac{8}{2}(10+38)[/tex]
[tex]S_{8} = 4(48)[/tex]
[tex]S_{8} = 4\times 48[/tex]
[tex]S_{8} = 192\ boxes[/tex]
Therefore, 192 boxes in the entire display.

Answer: [tex]average\ rate\ of\ change\approx-3[/tex]
Step-by-step explanation:
For this exercise you need to use the following formula:
[tex]average\ rate\ of\ change=\frac{f(b)-f(a)}{b-a}[/tex]
You need to find the average rate of change of the given function g(x) over the following interval:
[tex][-1,2][/tex]
So, you can see in the table that the point whose x-coordinate is -1, is:
[tex](-1,5)[/tex]
And the point whose x-coordinate is 2, is:
[tex](2,-3)[/tex]
Knowing this, let be:
[tex]a=-1\\f(a)=5\\\\b=2\\f(b)=-3[/tex]
Now you can substitute values into the formula:
[tex]average\ rate\ of\ change=\frac{-3-5}{2-(-1)}[/tex]
Finally, evaluating, you get that the average rate of change over the interval indicated in the exercise, is:
[tex]average\ rate\ of\ change=\frac{-8}{3}\\\\average\ rate\ of\ change=-2.66\\\\average\ rate\ of\ change\approx-3[/tex]

81 is 18% of what number?
Answer:
n = 450
Step-by-step explanation:
18%·n = 81
18·n/100 = 81
18n = 8100
n = 8100 : 18
n = 450
Answer:
81 is 18% of 450.
Step-by-step explanation:
81 ÷ 18 = 4.5
4.5 x 100 = 450
450 - 18% = 369
450 - 369 = 81
So, 18% of 450 is 81 and 81 is 18% of 450.

Identify the formula for finding the nth term of an arithmetic sequence, where A(n) is the nth term of an arithmetic sequence, a is the first term,n is the term number and d is the common difference.
Option D: A(n) = a + (n – 1) d
Solution:
To identify the formula for finding the nth term of an arithmetic sequence.
Let a be the first term.
d be the common difference of the each term.
n be the term of the number.
A(n) be the nth term of the arithmetic sequence.
Arithmetic formula:
A(n) = a + (n – 1) d
Example: 1, 4, 7, 10, 13, 16, 19, ...
This is a arithmetic sequence.
a = 1, d = 4 – 1 = 3.
To find the 5th term:
Substitute this in the above formula, we get
A(n) = a + (n – 1) d
A(5) = 1 + (5 – 1) 3
= 1 + 4(3)
= 1 + 12
A(5) = 13
In the given sequence 5th term is 13.
Hence Option D is the correct answer.
A(n) = a + (n – 1) d
Answer:
A(n) = a + (n - 1)d
