To write an equation for a line that is parallel to a given line and passes through a given point, use the point-slope form of the linear equation. The slope of the parallel line is equal to the slope of the given line. Plug in the values and simplify to get the equation.
Explanation:To find an equation for a line that is parallel to the given line and passes through the given point, we need to use the fact that parallel lines have the same slope. The slope of the given line is 3/4, so the slope of the parallel line will also be 3/4. Using the point-slope form of a linear equation, we can write the equation:
y - y1 = m(x - x1)
where (x1, y1) is the given point and m is the slope. Plugging in the values, we get:
y - (-18) = 3/4(x - (-8))
Simplifying the equation gives:
y + 18 = 3/4(x + 8)
Next, we can distribute the 3/4 to both terms in the parentheses:
y + 18 = 3/4x + 6
To isolate y, we subtract 18 from both sides:
y = 3/4x - 12

Answer: The answer is (a) 15.
Step-by-step explanation: We are given a figure with two similar triangles with sides of lengths x, 15 and corresponding sides of lengths 15 and 25 respectively.
Since the given triangles are similar, so their sides will be proportional.
Therefore, we have
[tex]\dfrac{x}{9}=\dfrac{25}{15}\\\\\\\Rightarrow \dfrac{x}{9}=\dfrac{5}{3}\\\\\\\Rightarrow x=\dfrac{5\times 9}{3}\\\\\Rightarrow x=15.[/tex]

For which interval is the function constant?
(0, 2)
(−∞, −6)
(2, ∞)
(−6, 0)
Answer:
(−6, 0)
Step-by-step explanation:
The section where the function is constant is where it is horizontal. This is from x = -6 to x = 0; in interval notation, this is (-6, 0).
A function assigns the value of each element of one set to the other specific element of another set. The function is constant in the interval (-6 to 0).
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A function is known to be constant if the value of one of the variables is not changing the value of the other.
In the function as we can see that the value of y is not changing with the change in the value of x between x=-6 to 0, therefore, the function is constant in the interval (-6 to 0).

I have attached a picture of a question I am stuck on. It is about Riemann sums. I have attempted the question but did not get the correct answer :( Here is my work:
I see that this graph has the same area repeating 12 times.
I did (b - a)/n, or (12 - 0)/36, and found that the width of each rectangle should be 1/3. Because we are asked to find the area using "circumscribed angles," I will use right-endpoint rectangles on the first part of the graph that shows a decreasing interval from 0 to 1:
t = 1/3, r(t) = 2.01745506
t = 2/3, r(t) = 2
t = 1, r(t) = 1.45369751
These values for r(t) represent heights of the rectangles. I can add them and multiply by the width of each rectangle:
1/3(2.01745506 + 2 + 1.45369751) = 1/3(5.47115257) = 1.823717523
I can multiply the area by 12 to find the area under the entire function:
1.823717523 * 12 = 21.88461028
This is not an answer choice, so I clearly did something wrong! Can someone help me find my mistake?

The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.
The distance Train A traveled in 1 h is greater than the distance Train B traveled in 1 h.
The distance Train A traveled in 1 h is less than the distance Train B traveled in 1 h.
Answer:
Option A - The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.
Step-by-step explanation:
Given : The distance Train A traveled is modeled by the function [tex]d(t)=81t[/tex]
where d represents distance in miles and t represents time in hours.
To find : How does the distance Train A traveled in 1 hour compare to the distance Train B traveled in 1 hour?
Solution :
Distance traveled by Train A in 1 hour is
[tex]d(t)=81t[/tex]
[tex]d(t)=81(1)=81[/tex]
Distance traveled by Train B in 1 hour is
[tex]d(t)=81t[/tex]
[tex]d(t)=81(1)=81[/tex]
or for B, we have 324 miles in 4 hours. If that is at a constant speed, it travels 324/4 = 81 miles in one hour
Therefore, The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.
Hence, Option A is correct.
Answer:
The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.

Which properties did Carmen use to solve the following problem? 17 + (45 + 23) 17 + (23 + 45) (17 + 23) + 45 40 + 45 85 distributive property identity property of addition associative property of addition commutative property of addition
Carmen used the associative property of addition to solve the given problem.
The associative property means one can add or multiply the given numbers regardless of how they are grouped. In other words, if one is adding or multiplying it does not matter where the brackets are placed.
The given problem is -
17 + (45 + 23), 17 + (23 + 45), (17 + 23) + 45
So here the sum of all the three patterns is 85. This clearly proves that forming groups does not affect the sum. So this is based on associative property of addition.

C.
3q + 38
D.

Answer:
c i just took it
Step-by-step explanation:
The given expression simplifies to B. 13p - 17q + 2 by combining like terms.
The given expression that requires simplification is 7p + 20 - 13q - 4q - 18 + 6p. To simplify an algebraic expression, combine like terms, which are terms that contain the same variable raised to the same power. In this case, we combine the terms with p and the terms with q, as well as the constant terms separately.
First, combine the terms with p: 7p + 6p equals 13p.
Second, combine the terms with q: -13q - 4q combines to -17q.
Lastly, combine the constant terms: 20 - 18 equals 2.
Putting it all together, the simplified expression is 13p - 17q + 2, which corresponds to option B.
If f(x) = 3 – 2x and 1/x+5, what is the value of (f/g)(8)? –169 –1 13 104
The value of (f/g)(8) is -169 if the f(x) = 3 – 2x and g(x) = 1/(x+5) option (A) -169 is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have functions:
f(x) = 3 – 2x and
g(x) = 1/(x+5)
To find the value of (f/g)(8):
First, find the value of f(x) at x = 8
Plug x = 8 in the function f(x)
f(8) = 3 - 2(8)
f(8) = 3 - 16
f(8) = -13
Now plug the x = 8 in the function g(x)
g(8) = 1/(8 + 5)
g(8) = 1/13
(f/g)(8) = f(8)/g(8)
(f/g)(8) = -13/(1/13)
(f/g)(8) = -169
Thus, the value of (f/g)(8) is -169 if the f(x) = 3 – 2x and g(x) = 1/(x+5) option (A) -169 is correct.

Which of the following statements about special angle relationships is not correct?
A. It is possible for angles to be both vertical and complementary.
B. It is possible for an obtuse angle to have both a complement and a supplement.
C. It is possible for an acute angle to have both a complement and a supplement.
D. It is possible for angles to be both congruent and supplementary
Answer:
B.) It is possible for an obtuse angle to have both a complement and a supplement.
Step-by-step explanation:
Rules for an obtuse angle:
It cannot be smaller than or be 90°It can not be bigger than or be 180°To create a complementary or supplementary angle, you can use 2 angles and no more than 2.
Say we used an obtuse angle (like the one in the picture below), since an obtuse angle can not be or be greater than 90°, an obtuse angle can not be complementary.
We can not fit 2 obtuse angles at 180°, because of that, an obtuse angle(s) can not create a supplementary angle.
Therefore, B would be the correct answer.

At Saturday night’s football game there were 18 less fans than half the fans at Friday night’s game. There were “x” fans at Friday’s game. Write an expression to represent the number of fans at Saturday’s game
The expression to represent the number of fans at Saturday's game when there were 'x' fans on Friday is (1/2)x - 18.
Explanation:To find the number of fans at Saturday's football game based on the given information that there were 'x' fans at Friday's game, we will write a mathematical expression. According to the statement, there were 18 fewer fans than half of the fans on Friday night. The expression for half of the fans at Friday's game is (1/2)x and we subtract 18 from this to account for the 18 fewer fans. Therefore, the expression representing the number of fans at Saturday's game is (1/2)x - 18. This expression can be used to determine the number of fans at Saturday's game once the number of fans on Friday (x) is known.
The expression representing the number of fans at Saturday's game, based on the fact that there were 18 less than half the number of fans at Friday's game (represented by x), is (x/2) - 18.
Explanation:The question we are addressing involves writing an expression to represent the number of fans at Saturday's football game, with the information that there were 18 less fans than half the number of fans at Friday night's game, and there were x fans at Friday's game.
Let's start with the number of fans at Friday's game, which is represented by x. Since we know that Saturday's game had 18 less than half of that amount, we first need to find half of x. To do that, we divide x by 2: (x/2). Now, to reflect that there were 18 fewer fans on Saturday, we subtract 18 from half of x: (x/2) - 18. Consequently, the expression that represents the number of fans at Saturday's game is (x/2) - 18.
This expression allows us to plug in the actual number of fans from Friday's game (when we know it) to determine the number of fans that attended Saturday's game.
