Find the coordinates of B, C, and D given that AB = 5 and BC
= 10.
The coordinates of B, C, and D are (3,-5), (3,5), and (-7,5) respectively.
Given point A (-2,-5) and the lengths of the sides AB = 5 and BC = 10, we can use this information to determine the coordinates of B, C, and D.
Using the information provided, we know that B is 5 units away from A in the positive x-direction. Therefore, the x-coordinate of B is (-2) + 5 = 3 and the y-coordinate of B is the same as that of A, which is -5. So point B is (3,-5).
Next, we know that C is 10 units away from B in the positive y-direction. Therefore, the x-coordinate of C is the same as that of B, which is 3, and the y-coordinate of C is (-5) + 10 = 5. So point C is (3,5).
Finally, we know that D is 10 units away from C in the negative x-direction. Therefore, the x-coordinate of D is 3 - 10 = -7 and the y-coordinate of D is the same as that of C, which is 5. So point D is (-7,5).

A. Find 25% of $120 is this the price he will pay? B. Does Wyatt have enough
25 percent of $120 is $30 and yes, he has enough money to buy the music player.
A) Find 25% of $120:
To find 25% of $120, we divide $120 by 100 and then multiply by 25:
$120 / 100 * 25 = $30
So, 25% of $120 is $30.
B) Does Wyatt have enough:
To find the sale price of the music player, we need to apply the 24% discount:
$120 - $120 * 24% = $120 - $120 * 0.24 = $120 - $28.80 = $91.20
So, the music player will be sold for $91.20.

A graph is said to represent a function if a vertical line drawn anywhere on the graph of a relation only intersects the graph once by Slope of 3.75b + 5: 3.75
How do you know that a graph represents a function?A graph is said to represent a function if and only if any vertical line intersects it at one precise location. The vertical line only ever crosses the graph D, as seen when looking at the graphs.The graph does not represent a function if a vertical line can cross it at two or more places.In order to represent a function, you often use a function rule, such as y=2.50x, where x is the independent variable and y is the dependent variable. By creating a graph, you may visualize your function. Making a table of inputs and their matching outputs before creating a graph is the simplest way to create a graph.Example:
F(b) = 3.75b + 25

The equation of the trend line, can be found to be y = - 25 + 250
How to find the equation of the trend line ?To find the equation of the trend line, you first need to find the slope. To do this, pick two points on the trend line. ( 4, 150) and ( 8, 50 ).
The slope is:
= ( Y2 - Y1 )/ ( X 2 - X 1 )
= ( 50 - 150 ) / ( 8 - 4 )
= - 100 / 4
= - 25
The equation of the trend line takes the form:
y = mx + b
m = slope
b = y - intercept
The slope allows you to find the y - intercept :

He currently has $15. Write and solve an inequality to find how much more cash Marvin should put in his wallet.
Marvin should put at least $45 more cash in his wallet in order to have at least $60.
Solving inequality questionsLet x be the amount of cash that Marvin needs to put in his wallet. We know that he wants to have at least $60, and he currently has $15, so we can write the inequality as:
x + 15 ≥ 60
To solve for x, we need to subtract 15 from both sides of the inequality:
x ≥ 60 - 15
x ≥ 45

The graph represents the function f(x). Which set of points lie on its inverse f^-1(x)?
Answer:
Third choice: (1, -3); (2, 2); (3, 7)
Step-by-step explanation:
There are two ways to solve this
The easiest way to solve this is to understand that the inverse of a function f(x), denoted by f⁻¹(x) is nothing but a reflection of the function about the line y = x
What that means is that if (x, y) is a specific point on the line, then the inverse point will be (y, x). Basically we are swapping the x, y values
The 3 points on f(x) and the corresponding points on f⁻¹(x) are given below:
f(x) f⁻¹(x)
------ --------
(-3, 1) (1, -3)
(2, 2) (2, 2)
(7, 3) (3, 7)
From the options given we see that the 3rd choice gives the correct values

adding and subtracting fractions with whole numbers
The steps for adding and subtracting fractions with whole numbers:
- Write the whole number in the form of a fraction.
- Convert the fractions to like fractions.
- Add/Subtract the numerators while the denominator remains the same.
We know that the fraction is used to represent the portion or part of the whole thing.
The fraction has two parts: numerator and denominator.
The top part of fraction is numerator and the bottom part of fraction is denominator.
consider a fraction 1/8.
Here, numerator is 1, denominator is 8
When certain thing is divided into 8 equal parts then each part of is represented by fraction1/8
In case of adding and subtracting fractions with whole numbers:
Let us assume that 'a' represents the whole number and [tex]\frac{x}{y}[/tex] be fraction
First we write the whole number in the form of a fraction.
So, a = [tex]a = \frac{a}{1}[/tex]
Now we find the LCM of the denominators of fractions [tex]\frac{a}{1} ,\frac{x}{y}[/tex] and then convert the given fractions to like fractions.
Let m be the LCM of the denominators of fractions [tex]\frac{a}{1} ,\frac{x}{y}[/tex]
So, the fractions becomes [tex]\frac{a}{m} ,\frac{x}{m}[/tex]

A square painting has a diagonal of 44 in. Lorraine wants to frame the picture. The framing material is sold by the inch.
What is the minimum amount of framing she needs?
The minimum amount of framing Lorraine needs for the square painting is 31 inches.
We can use the Pythagorean theorem to calculate the length of the side of the square given the length of its diagonal. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
We know that the diagonal of the square painting is 44 inches, and since the diagonal of a square bisects its angles, the square can be divided into two congruent right-angled triangles. Therefore, the length of one side of the square can be calculated using the Pythagorean theorem:
44 inches^2 = x^2 + x^2
x^2 = 11*11
x = 11 inches
Since the square painting has a side length of 11 inches, and the framing material is sold by the inch, Lorraine will need a minimum of 11 inches of framing on each side, for a total of 44 inches.

may u answer this with equation im very confused pls
Answer:
See explanation below.
Step-by-step explanation:
1. (-1, -1) and (2, -2)
m = -2+1 / 2+1
m = -1/3
2. (-1, -4) and (0, -1)
m = -1+4 / 0+1
m = 3/1
m = 3
3. (-4, 0) and (-2, -3)
m = -3-0 / -2+4
m = -3/2
4. (2, 0) and (0, -3)
m = -3-0 / 0-2
m = -3/-2
m = 3/2
5. (-1, 2) and (-4, -3)
m = -3-2 / -4+1
m = -5/-3
m = 5/3
6. (4, 3) and (1, -4)
m = -4-3 / 1-4
m = -7/-3
m = 7/3
