Coordinates of L after rotation are (-8,4)
What are the rules of 270 degrees rotation of coordinates about the origin?
Assuming that the rotation is about (0,0)
then after 270° clockwise rotation (x, y) becomes (-y, x)
and after 270° anticlockwise rotation (x, y) becomes (y,-x)
Given that LMN with vertices L(4,8), M(4,3) and N(8,8) is rotated 270° clockwise about the origin
Then for L(4,8) as the rotation is 270° clockwise then
(x, y) = (4,8)
and after 270° clockwise rotation (x, y) becomes (-y, x)
Therefore new coordinates of L are (-8,4)

Find the measures of the interior angles of the triangle
please help
Answer: x = 88 degrees
Step-by-step explanation:
The angles of a triangle add up to 180 degrees.
So
48 + x + (x - 44) = 180
48 + 2x - 44 = 180
2x + 4 = 180
2x = 176
x = 88
Angle B = 88 degrees
Angle C = 44 degrees
For each of the following functions, evaluate: f(-4), f(-2), f(0), f(2), and f(4)
17.)f(x)=3x-7

The equation 6x − 8 = 4x represents two cars traveling in opposite directions, where x represents the distance in miles between the cars. what is the distance, in miles, between the cars? x = 0.8 x = 4 x = 8 x = 16
Distance between two cars travelling in opposite directions with the equation 6x - 8 = 4x where x is the distance in miles is equal to 4 miles.
As given in the question,
Two cars travelling in opposite directions
x represents the distance in miles
Equation :
6x - 8 = 4x
⇒ 6x - 4x = 8
⇒ 2x = 8
⇒ x = 4miles
Therefore, the distance between two cars travelling in opposite directions with the equation 6x - 8 = 4x where x is the distance in miles is equal to
4miles.

Solution :
Pennies :
The dollar is the United States' 100-cent coin. It takes 100 pennies to equal a dollar
1. Girl deposit 5 pennies for each day
which means after 10 days = 50 pennies
Her sister gave her 3 pennies = 53 pennies total she has

She needs how many pinnies to do so.
1 doller = 100 pennies
1.5 doller = 100* $ 1.5 = 150 peniess
2.
Gallons :
A gallon of water by definition is 128 fluid ounces in the United States. Water bottles can vary in size, but the total number of bottles making up 128 ounces can fit in a gallon. For example, if the water bottle is 16 ounces in size, then 8 of these make up a gallon.
pool capacity = 1500 gallons of water
then
every 5 minutes = 2 gallons of water
then,
after 50 minutes = 2*10 gallons of water

A= 89cm root 2 square
Considering the given area of the square, it is found that it's side length is an irrational number.
What is the missing information?This problem is incomplete, but researching it on a search engine, it asks if the side length of the square of area 89 cm² is rational or irrational.
What is the formula for the area of a square?
The area of an square of side length s is given by s squared, as follows:
A = s².
In this problem, the area is of 89 cm², hence:
s² = 89.
s = sqrt(89).
The square root of 89 is a non-exact root, hence it cannot be represented by fraction and is an irrational number.

Create a data set of 9 numbers that has a mean of 10 and a maximum of 15
Other answers are possible.
=========================================================
Explanation:
Let's say 10 is the median, and we'll have four values above it and four below. This gives 4+1+4 = 9 total items. One such example could be {6,7,8,9,10,11,12,13,14}. This is the set of whole numbers from 6 to 14 inclusive.
Due to the symmetry of that list, the mean = median = 10
The only problem is the max is 14, when we want it to be 15. We can fix this by adding 1 to each of the upper four values {11,12,13,14} to get {12,13,14,15}.
To balance things out, subtract 1 from each of the lower four values. So we go from {6,7,8,9} to {5,6,7,8}. This balancing is to keep the mean the same at 10.
Therefore, the set {6,7,8,9,10,11,12,13,14} becomes {5,6,7,8,10,12,13,14,15} which is one possible answer.
There are infinitely many other possible answers. The data set does not have to be symmetric like this.

Answer the question in photo [ Brainliest + 20 points ]
Answer:
27 units
Step-by-step explanation:
First lets add the 2 segments on the top.
8x-11 + 14x-15
Then we can add the like terms together to get
22x-26
The equation above is equal to the equation below the number line, since we added the two on top together, so:
22x-26=19x-17
Now we can start solving
Add 26 to both sides and subtract 19 from both sides
3x=9
Now we can divide by 3
x=3
TU is 14x-15, so we can substitute in 3 for x
14*3-15
42-15
27
Answer:
27 units
Step-by-step explanation:
Set up an equation:
8x -11 + 14x -15 = 19x - 17
Combine like terms:
22x - 26 = 19x -17
Subtract 19x on both sides:
(22x - 26) - 19x = (19x - 17) - 19x
3x - 26 = -17
Add 26 on both sides to isolate the x term:
(3x - 26) + 26 = (-17) + 26
3x = 9
Then, divide by 3 on both sides to fully isolate x:
3x / 3 = 9 / 3
x = 3
Plug 3 for x into the formula for TU:
14(3) - 15 = x
42 - 15 = x
x = 27
TU = 27 units

A student states that a triangle can be formed with side lengths 3 in, 5 in, and 9 in. is the student correct? why, or why not? yes, because 3 5 < 9 yes, because 3 9 > 5 no, because 3 9 > 5 no, because 3 5 < 9
A student is not correct when he stated that a triangle can be formed with side lengths 3 in, 5 in, and 9 in because 3 + 5 < 9.
A triangle is a polygon with three sides and three vertices.
To know if a set of numbers is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.
let a = 3, b = 5, and c = 9
a + b > c : 3 + 5 > 9 8 > 9 False
a + c > b : 3 + 9 > 5 12 > 5 True
b + c > a : 5 + 9 > 3 14 > 3 True
If at least one of these statements does not hold true, the measurements can't be the sides of a triangle.

The segment addition postulate is applicable only to a line segment, and does not apply to a ray or a line. A line segment differs from a ray or a line as it is bounded by two defined endpoints.

From the given information:
The girls group rented 2 canoes and three inner tubes for a complete cost of $80. The boys group rented 1 canoe and seven inner tubes for a complete cost of $95.
Then
Let c is that the cost of renting a canoe and t is that the cost of renting inner tubes.
For the ladies,
2c + 3t = 80
For the boys,
c + 7t = 95
Solving the system of equations, multiply the second equation by 2 and subtract them.
2c + 3t = 80
2c + 14t = 190
11t = 110
t = 10
Now,
Substitute t to either equations,

v = 5 miles per 45 minutesx = 36 milest = ?Calculating the velocity we have:
v = x/t
v= 5 miles/45 min
v = 0.111 miles/ min
