Step-by-step explanation: To understand how to combine like terms, let's look at an example.
9c + 2c
The two parts of this expression, +9c and +2c, are called terms. The numbers in front of the variables, +9 and +2, are called coefficients.
Since the variables, c and c, are identical, the two terms in this problem are called like terms.
Like terms can be added together by simply adding their coefficients.
So in this problem, since 9 + 2 = 11, 9c + 2c is simply 11c.

Why does the slope formula not work for vertical lines?
17 − 2v = 41 solve v
Final answer:
To solve the equation 17 - 2v = 41, subtract 17 from both sides to get -2v = 24. Then divide both sides by -2 which gives v = -12.
Explanation:
To solve the equation 17 - 2v = 41 for v, first we need to isolate v on one side of the equation. We can start by subtracting 17 from both sides to rid the left side of numbers without the variable v. This gives us the equation:
-2v = 41 - 17
-2v = 24
Now, to solve for v, we divide both sides of the equation by -2:
v = 24 / (-2)
v = -12
Therefore, the solution to the equation is v = -12.

What is the degree of the power function represented in the table?
1
2
3
4
x h(x)
−2 −8
−1 −2
0 0
1 −2
2 −8
Answer: Second option.
Step-by-step explanation:
In order to find the degree of the power function represented in the given table, you must find the difference of the y-values (values of [tex]h(x)[/tex]) until they diferences are constant.
1) First differences:
[tex]-2-(-8)=6\\\\0-(-2)=2\\\\-2-0=-2\\\\-8-(-2)=-6[/tex]
2) Second differences:
You must find the differences between the First differences. Then, you get:
[tex]2-6=-4\\\\-2-2=-4\\\\-6-(-2)=-4[/tex]
You can notice that the second differences are constant. This means that the degree of the power function represented in the given table is:
[tex]Degree=2[/tex]
The degree of the power function represented in the table is [tex]\boxed2[/tex].Option (b) is correct.
Further explanation:
Given:
The options are as follows,
(a). 1
(b). 2
(c). 3
(d). 4
Explanation:
The highest power of the polynomial function is known as the degree.
The value of x is -2 and the value of the function is -8.
The value of x is -1 and the value of the function is -2.
The value of x is 0 and the value of the function is 0.
The value of x is 1 and the value of the function is -2.
The value of x is 2 and the value of the function is -8.
The function from the table can be expressed as follows,
[tex]f\left( x \right) = - 2{x^2}[/tex]
Substitute [tex]-2[/tex] for [tex]\text{x}[/tex] in equation [tex]f\left( x \right) = - 2{x^2}.[/tex]
[tex]\begin{aligned}h\left( { - 2}\right) &= - 2\times {\left( { - 2} \right)^2}\\&= - 2 \times 4\\&= - 8\\\end{aligned}[/tex]
The degree of the power function represented in the table is [tex]\boxed2.[/tex]Option (b) is correct.
Option (a) is not correct.
Option (b) is correct.
Option (c) is not correct.
Option (d) is not correct.

34 days to 2 weeks the ratio is
The ratio of 34 days to 2 weeks is [tex]\(\frac{34}{2 \times 7}\)[/tex].
To find the ratio of 34 days to 2 weeks, we first need to convert 2 weeks into days, since there are 7 days in a week. Therefore, 2 weeks is equivalent to [tex]\(2 \times 7\)[/tex] days, which is 14 days.
Now, we can set up the ratio of 34 days to 14 days (2 weeks):
[tex]\[ \text{Ratio} = \frac{34 \text{ days}}{14 \text{ days}} \][/tex]
To simplify this ratio, we can divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 34 and 14 is 2.
Dividing both by 2, we get:
[tex]\[ \text{Ratio} = \frac{34 \div 2}{14 \div 2} = \frac{17}{7} \][/tex]
So, the simplified ratio of 34 days to 2 weeks is [tex]\(17:7\) or \(\frac{17}{7}\)[/tex].

How to determine the domain and range of a rational function?
The table shows the annual profits (in thousands of dollars) of a county fair from 2008 to 2012. What must the 2012 profit be (in hundreds of dollars) to break even over the five-year period?
Answer:
In year 2012, 0.45 thousands dollars will bring the break even for the company.
Step-by-step explanation:
The table shows the annual profits of a county fair from 2008 to 2012.
We have to calculate the profit in 2012 to get the break even over the five year period.
Total profit in four years = profit in year (2008 + 2009) = 2.5 + 1.75 = 4.25 thousand dollars
Total loss in four years = loss in year (2010 + 2011) = 3.3 + 1.4 = 4.7 thousand dollars
Net profit or loss = Net profit - net loss = 4.25 - 4.7 = -0.45
There is a net loss of 0.45 thousand dollars.
If we get a profit of 0.45 thousand dollars in year 2012, we will be in the situation of no profit and no loss (break even).
Therefore, profit of 0.45 thousands of dollars is the answer.

Seven years ago, kodi found a box of old baseball cards in the garage. since then, he has added a consistent number of cards to the collection each year. he had 52 cards in the collection after 3 years and now has 108 cards. kodi looking into his box of baseball cards. how many cards were in the original box? is this t(0) or t(1)? write the first few terms of the sequence. kodi plans to keep the collection for a long time. how many cards will the collection contain 10 years from now? write an equation that determines the number of cards in the collection after n years. what does each number in your rule represent?
The required equation is y = 14x + 10 which is the number of cards in the collection and he will have 150 cards after 10 years
What is the slope of the line?The slope of the line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
As per the question, we take the two points are (3,52) (7,108)
So slope = (108 - 52) / (7 - 3) = 56/4 = 14
y = mx + b
slope(m) = 14
Substitute the value of x = 3 and y = 52 in the equation
52 = 3(14) + b
52 = 42 + b
52 - 42 = b
10 = b
So the original amount of cards is 10
If x represents the number of years, while y is the total number of cards.
y = 14x + 10
He began with 10 cards and has added 14 cards every year thereafter.
So after 10 years
y = 14(10) + 10
y = 140 + 10
y = 150
Therefore, he will have 150 cards after 10 years
