Answer:
X (2, 1)
Y (2, 3)
W (5, 5)
Step-by-step explanation:
The current points are:
X (-2, -1)
Y (-2, -3)
W (-5, -5)
Now, after rotating 180 degrees around the origin, here is what points Y, Y, and W would look like:
X (2, 1)
Y (2, 3)
W (5, 5)
Plot these new points on the graph, and you'll have a new figure which will be rotated to 180 degrees.
I have also provided you with a graph, showing both, the original and the rotated version, below.

-16 + the quotient of a
number and -4 is -3
Answer:
76
Step-by-step explanation:
let the number be x
Then 16 + x/-4 = -3, so
x/-4 = -16-3 = -19 (add -16 on both sides)
x = -4*-19 = 76 (multiply by -4 on both sides)
If Y is the midpoint of R and T. and RY = 3x - 2 and YT = 8x - 22. Find the
value of RT. *
Your answer
Answer:
11x-24
Step-by-step explanation:
All you have to do is add (3x-2)+(8x-22)=11x-24.
Answer:
RT = 20
Step-by-step explanation:
Since Y is the midpoint of RT , then
RY = YT , that is
3x - 2 = 8x - 22 ( subtract 8x from both sides )
- 5x - 2 = - 22 ( add 2 to both sides )
- 5x = - 20 ( divide both sides by - 5 )
x = 4
Then
RT = RY + YT = 3x - 2 + 8x - 22 = 11x - 24 , so
RT = 11(4) - 24 = 44 - 24 = 20
Plot the image of point A under a reflection across line
l.
Answer:
Just from point a go 8 spaces to the left and place the dot over there.
Step-by-step explanation:
Since you are getting a reflection of a you need to move 4 spaces to the left of the line to get an exact mirror of point a or relfelction.
To plot the reflected point of A under a reflection across line l, just move 8 units across the line "l" horizontally.
The reflected point of A should be written as A'.

Which model shows the comparation?
the Devision model comparation
help due today please
Answer:
angle ABD =55 degree
angle BCD= 125 degree
Step-by-step explanation:
angle ABD and angle DBC are supplementary angles.
Hence, angle ABD +angle DBC = 180 --equation 1
angle ABD = (2x+15) ---equation 2
angle BCD = (4x+45) ------equation 3
ABD+DBC=180
(2x+15) + ( 4x+45 ) = 180
2x+4x+15+45=180
6x+60=180
6x=180-60
6x=120
x=120/6=20
angle ABD= 2x+15= 2(20) +15
=40+15= 55 degree
angle BCD= 4x+45 = 4(20) +45
= 80+45= 125 degree
Hence, angle ABD =55 degree
angle BCD= 125 degree
Hope this helps.

and engineers didn’t answer 68 questions correctly on a 170 question trigonometry test what percent of the questions did she answer correctly?
Answer:
60%
Step-by-step explanation:
You see how many answers she got got right and to do that you subtract 170-68 and get 102. That's how many she answered correctly. Then you need to find the percentage and to do that you divide 102 by 170 which gives you 0.6, which can be read as 60%. Hope that helps! :)

Find the value of x and y
Answer:
x = 10 and y = 15
Step-by-step explanation:
The arrows on lines AB and CD indicate that they are parallel. This means that we have to look for Z-angles (I don't know if they are called the same where you're from but I hope you recognise the term). This means that ∠ABC = ∠BCD
5x - 20° = x + 20°
4x = 40°
x = 10°, which gives us the first answer.
The angle formed by points ACE (a straight line) is 180 degrees. Lets refer to this as angle ACE. We also know this angle consists of angle ACB, BCD and DCE. This gives us the following equation:
angle ACE = angle ACB + x + 20° + y + 20° = 180°
angle ACB + x + y + 40° = 180°
angle ACB = -x - y + 140°
Inserting the x we found earlier this gives
∠ACB = - y + 130°
Now we can find a second equation to describe ACB by looking at the triangle it is inside. The angles in a triangle always add up to 180°, giving the following expression:
4y - 25° + 5x - 20° + ∠ACB = 180°
Substituting x again gives
4y - 25° + 50° - 20° + ACB = 180°
ACB = 180 - 4y - 5° = 175° -4y
Combining the two expressions for ACB gives the final equation to solve:
175° - 4y = -y + 130°
-3y = -45
y = 15

Find the measure of the missing angle of each
Answer:
? = 120, ? = 145, respectively
Step-by-step explanation:
? + 60 = 180
? (+ 60 - 60) = 180 - 60
? = 120
35 + ? = 180
(35 - 35) + ? = 180 - 35
? = 145

if a + b + c is cast 20 and a + b is equal to 14 , then c is what by process
Answer:
6
Step-by-step explanation:
[tex]a + b + c = 20[/tex]
[tex]a + b = 14(i)[/tex]
Putting value (a + b) in the above equation
[tex]14 + c = 20[/tex]
[tex]c = 20 - 14[/tex]
[tex]c = 6[/tex]
