Quadrants I and II.
O: (-2, 2)
N: (-2, 4)
M: (1, 4)
P: (1, 2)
Step-by-step explanation:
When rotating about the origin 90 degrees in a counterclockwise direction, focus on the coordinates of one point on the preimage at a time. So, the x-coordinate on the image will be the opposite of the y-coordinate of the preimage, and the y coordinate of the image will be the x-coordinate of the preimage. That sounds complicated so here is an example from the problem.
O is a point on the preimage. Its coordinates are (2, 2). To find the x-coordinate, take the opposite of the image's y-coordinate. The y-coordinate is 2, so it will be a -2 x-coordinate on the image. To find the y-coordinate on the image, take the x-coordinate of the preimage (O). The x-coordinate of O is 2, so the y-coordinate of the image will be 2. Combine those together and after a 90 degree counterclockwise rotation, you get a point of (-2, 2)
Answer:
Step-by-step explanation:
when rotate counterclock wise 90 degrees:
(x,y)⇒(-y,x)
points (2,2) (4,2) (2,-1) (4,-1)
CCW90 degrees (-2,2) (-2,4) (1,2) (1,4)
CCW 270 degrees (2,-2) (2,-4) (-1,-2) (-1,-4)
(x,y)⇒(y,-x) the shape will be in quadrant 3 and 4

Answers
Answer:
x = -19; y = 25/3
Step-by-step explanation:
Step 1: solve the equation with only one variable
Isolate the variable (x)
x + 10 = -9
x = -9 - 10
x = -19
Step 2: input new information into the other equation
If x = -19, then:
2(-19) - 6y = 12
Isolate the variable (y)
-38 - 6y = 12
-6y = 12 + 38
-6y = 50
y = 50 ÷ 6
y = 50/6
Simplify
y = 25/3

Answers
Answer:d
Step-by-step explanation:I took the quiz
The property that refers to the density of the medium's particles at the compression of a sound wave is the amplitude of the wave.
What is Sound?The vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.
amplitude of the wave is the property which represents the density of the medium's particles at the compression of a sound wave.
The maximum displacement of the particles in the medium from their rest position as the wave passes through them is the amplitude of the wave.
Amplitude refers the maximum pressure variation of compression and rarefaction that the sound wave creates in the medium.
Hence, property that refers to the density of the medium's particles at the compression of a sound wave is the amplitude of the wave.

X intercept: Y interce
Step-by-step explanation:
The required equation of the line that is perpendicular to the line x = 5 is y = 4.
Given that,
To determine the equation of the line that contains the point (3,-4) and is perpendicular to the line x = 5.
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
Here,
Slope of the given line x = 5 is m = 1 / 0
Now, the slope of the line perpendicular to the line x = 5 can be given as M,
Now,
Mm= - 1
M * 1 / 0 = 0 (since m = 1 / 0)
Here, the line passes through the point (-3, 4) and the slope is m = 0,
Since the equation of the line,
y - 4 = 0 (x + 3)
y - 4 = 0
y = 4
Thus, the required equation of the line that is perpendicular to the line x = 5 is y = 4.

A rectangular rug has a perimeter of 68 feet. The width of the rug is four less than the length.
The width of the rug is
feet.
Answers
Answer:
The width is 15 feet.
Step-by-step explanation:
I took 68 and divided it by 4, since there are four sides of the rectangular rug, and got 17.
I then took 17 and split 4(the difference in length and width) to get two.
17ft+2ft=19ft
17ft-2ft=15ft
Double checking that everything adds up:
19+19+15+15=68
Using the clue words in the problem, I know the width will be smaller than the length, so I know it's 15 feet.
I hope this helped! :)

Basically if you look at the lemonade the bar stops at 12
and for the water the bar stops between 6 and 8 which is 7
and the question says how many more which is minus so
The number of lemonades - the number of water sold=
12-7=5
Answer:
Lemonade sold 5 more than water
Step-by-step explanation:
The question is asking of the difference between lemonade and water that were sold. The graph shows us that 7 water was sold and 12 drinks of lemonade were sold. Since we're finding the difference, the equation would be 12-7, which equals to 5.

The soccer field at a park is 9000 square yards. The soccer field takes up 6 2/5 square inches on the map of the park. How many square yards does 1 square inch on the map represent? show your work
Answers
Answer: 1406.25 or 1406 1/4
Step-by-step explanation:
From the question, we are informed that a soccer field at a park is 9000 square yards and that the soccer field takes up 6 2/5 square inches on the map of the park.
To calculate how many square yards does 1 square inch on the map represent, we divide 9000 by 6 2/5. This will be:
= 9000 ÷ 6 2/5
= 9000 ÷ 6.4
= 1406.25 or 1406 1/4
1 square inch on the map represents 1406.25 square yards.
Answer: 45,000 / 32 or 1,406 and 1/4
