The equation y = x + 1 defines the relationship between x and y, where x is the input and y is the output. Which statements about the graph of this relationship are true? Select two that apply.
A.The graph is a curved line.
B.The graph is a straight line.
C.the graph is a vertical line.
D.The graph represents a function.
E.The graph has no negative outputs.
F.The graph passes through the origin.
Answers
All in all, your answers are B and D.
Let's go through all of our options.
A) It's defintely not curved; it's written in slope intercept form and is indeed a straight line.
B) Yes, the graph is a straight line. Although it's at an angle, it has no curves or flaws, and is completely straight.
C) The graph is not vertical. It has a y intercept and slope and therefore isn't. That's because it has a rate of change, and it crosses the y axis at some point depending on the slope, or rise over run. Vertical lines really don't have that.
D) Yes, the graph is a function. This is because it does not have two x values for one y, and does not fail the straight line test, which states that you can place a straight line anywhere on the graph and it can only go through one point.
E) This is false. If we put in -5 as our input, we add 1 and get -4, which is a negative output. Your output here depends on the input you put in, and the sign usually remains considering it's +1.
F) This graph does not pass through the origin. This is because the origin has a point at 0,0 and since it's x+1, it would be 0,1 instead because your output is adding one to that 0.

Answers
A common computer programming rule is that names of variables must be between one and eight characters long. The first character can be any of the 26 letters, while successive characters can be any of the 26 letters or any of the 10 digits. For example, allowable variable names include A, BB, and M3477K. How many different variable names are possible? (Ignore the difference between uppercase and lowercase letters.)
Answers
In our case it does not depend and we have combinations.
One character name:
Number of combinations = 26
Two characters name:
Number of combinations = 26*36
Three characters name:
Number of combinations = 26*36*36
Four characters name:
Number of combinations = 26*36*36*36
Five characters name:
Number of combinations = 26*36*36*36*36
Six characters name:
Number of combinations = 26*36*36*36*36*36
Seven characters name:
Number of combinations = 26*36*36*36*36*36*36
Eight characters name:
Number of combinations = 26*36*36*36*36*36*36*36
To find out how many different variable names are possible we need to add these numbers:
26 + 26*36 + 26*36*36 + 26*36*36*36 + 26*36*36*36*36 + 26*36*36*36*36*36 + 26*36*36*36*36*36*36 + 26*36*36*36*36*36*36*36 =
= 26 + 936 + 33696 + 1213056 + 43670016 + 1572120576 + 56596340736 + 2037468266496 =
= 2095684645538
The total number of different variable names possible is approximately 2,096,883,896,418.
To calculate the number of possible variable names, we need to consider the constraints on the variable names:
1. The first character must be one of the 26 letters.
2. Each subsequent character can be either one of the 26 letters or one of the 10 digits, totaling 36 possible characters (26 letters + 10 digits).
We need to consider variable names of lengths from 1 to 8 characters. We'll calculate the number of possible variable names for each length and then sum them.
1. For a 1-character name:
- There are 26 possible names (one for each letter).
2. For a 2-character name:
- The first character has 26 options.
- The second character has 36 options.
- Total for 2 characters: [tex]\(26 \times 36\)[/tex].
3. For a 3-character name:
- The first character has 26 options.
- Each of the second and third characters has 36 options.
- Total for 3 characters: [tex]\(26 \times 36 \times 36\)[/tex].
4. For a 4-character name:
- The first character has 26 options.
- Each of the second, third, and fourth characters has 36 options.
- Total for 4 characters: [tex]\(26 \times 36 \times 36 \times 36\)[/tex].
5. For a 5-character name:
- The first character has 26 options.
- Each of the second, third, fourth, and fifth characters has 36 options.
- Total for 5 characters: [tex]\(26 \times 36 \times 36 \times 36 \times 36\)[/tex].
6. For a 6-character name:
- The first character has 26 options.
- Each of the second, third, fourth, fifth, and sixth characters has 36 options.
- Total for 6 characters: [tex]\(26 \times 36 \times 36 \times 36 \times 36 \times 36\)[/tex].
7. For a 7-character name:
- The first character has 26 options.
- Each of the second, third, fourth, fifth, sixth, and seventh characters has 36 options.
- Total for 7 characters: [tex]\(26 \times 36 \times 36 \times 36 \times 36 \times 36 \times 36\)[/tex].
8. For an 8-character name:
- The first character has 26 options.
- Each of the second, third, fourth, fifth, sixth, seventh, and eighth characters has 36 options.
- Total for 8 characters: [tex]\(26 \times 36 \times 36 \times 36 \times 36 \times 36 \times 36 \times 36\)[/tex].
Now we sum these values to get the total number of possible variable names:
[tex]\[\begin{aligned} \text{Total} = & \ 26 + 26 \times 36 + 26 \times 36^2 + 26 \times 36^3 \\ & + 26 \times 36^4 + 26 \times 36^5 + 26 \times 36^6 + 26 \times 36^7\end{aligned}\][/tex]
Calculating each term separately and summing them:
[tex]\[\begin{aligned} & 26 = 26 \\ & 26 \times 36 = 936 \\ & 26 \times 36^2 = 33,696 \\ & 26 \times 36^3 = 1,213,056 \\ & 26 \times 36^4 = 43,669,056 \\ & 26 \times 36^5 = 1,572,085,056 \\ & 26 \times 36^6 = 56,595,062,016 \\ & 26 \times 36^7 = 2,038,722,232,576\end{aligned}\][/tex]
Summing these:
[tex]\[\begin{aligned} \text{Total} = & 26 + 936 + 33,696 + 1,213,056 + 43,669,056 \\ & + 1,572,085,056 + 56,595,062,016 + 2,038,722,232,576 \\ \approx & 2,096,883,896,418\end{aligned}\][/tex]

Eddie has m muffins. He splits them evenly among 9 boxes. Write an expression that shows how many muffins are in each box.
Answers
To find out how many muffins are in each box, divide the total number of muffins by the number of boxes. There would be 5 muffins in each box if Eddie has a total of 45 muffins.
Explanation:To write an expression that shows how many muffins are in each box, we can divide the total number of muffins by the number of boxes. Let's call the total number of muffins 'm' and the number of boxes '9'. The expression would be:
m ÷ 9
For example, if Eddie has 45 muffins, substituting 'm' with 45 in the expression would give us:
45 ÷ 9 = 5
Therefore, there would be 5 muffins in each box if Eddie has a total of 45 muffins.

Answers
Answer: 126 square inches
Explanation:
Trapezoid is a quadrilateral , shape with straight sides that has a pair of opposite sides parallel.
I already attached the image of trpazoid.
Now find the area of trapazoid.
We have a formula to find the area of trapezoid.
Area of trapezoid = [tex] \frac{a + b}{2} h [/tex]
where a & b are the parallel side ( here "a" represent the upper side and "b" represent the base)
h is the height of the trapezoid (always remember heigth is the perpendicular distance)
now a = 12 inches (AB)
b = 2 + 12 + 2 (CD = CE + EF + FD) = 16 inches
h = 9 (BE)
Now put all these values in the given formula
Area of trapezoid = [tex] \frac{12 + 16}{2} (9) [/tex]
= [tex] \frac{28*9}{2} [/tex]
= 14*9
Are of trapezoid = 126 sq in (3rd option is correct)

3. The questions asks for the amount of simple interest. The formula for simple interest is prt, where p = principal, r = rate, t = time. In this case, we are talking about 3 of them. 25,000 * 3 is 75,000. Now, let's multiply that number by 3% to find the amount of interest. 75,000 * 3% (0.03) is 2,250. Because this is only for one year, the number remains the same, so we don't have to multiply anything. There. The Branson family earns $2,250 in interest in one year. The answer is C.

Since there are 60 minutes in an hour, that's the same as 1800/60 which equals to 30 hours. If there are 6 people sharing Ashley's work Ashley + 5 friends the work will be finished 6 times as fast.
