On a coordinate plane, triangle X prime Y prime Z prime has points (negative 4, 5), (negative 6, negative 1), and (negative 2, negative 1).
Triangle XYZ was dilated using the rule DO,0.25 (x, y) → (0.25x, 0.25y).
The image is shown in the diagram. What are the coordinates of Z of the pre-image?
(–8, –4)
(–8, 2)
(–2, –1)
(–0.25, –0.5)
Answer:
(–8, –4)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the reduction or enlargement of the size of an object by a factor.
Given that triangle XYZ was dilated using the rule (x, y) ⇒ (0.25x, 0.25y) to produce triangle X'Y'Z' with points at X'(-4, 5), Y'(-6, -1) and Z'(-2, -1)
Since (x, y) ⇒ (0.25x, 0.25y)
(x, y) ⇒ 0.25(x, y)
4(x, y) ⇒ (x, y)
We can find the points of XYZ by multiplying by 4
hence:
X = 4(-4, 5) = (-16, 20)
Y = 4(-6, -1) = (-24, -4)
Z = 4(-2, -1) = (-8, -4)

Answer:
x = 25
F = 82
Step-by-step explanation:
Adjacent angles in a parallelogram are supplementary.
(4x -2)° +(3x +7)° = 180°
7x = 175 . . . . . . . . . . . . . . . divide by °, subtract 5, collect terms
x = 25 . . . . . . . . divide by 7
The far right angle is then ...
(3x +7)° = (3(25) +7)° = 82°
The opposite angle in the parallelogram has the same measure, as does the vertical angle to it, angle f.
∠f = 82°

There are 2 out of 10 that are blue so in fraction form thats 2/10 so when you simplify it, the simplest form is 1/5
how were people’s lives changed by the new technologies of the 1920s?
A. Labor-saving devices gave people more leisure time.
B. New farm machinery increased agricultural production.
C. Mobile devices allowed people to communicate more effectively.
D. National television broadcasts united the country.
A, please give brainly if correct. Thanks :D
Technology affected American lifestyles in two main ways. First, it gave Americans more leisure time. By the 1920s, there were many more labor saving devices, particularly ones that reduced the difficulty of housework. These gave Americans more time to do things other than simply working.
Tech has influenced american lives in two ways. For starters, it offered more leisure time for americans. Even by the 1920s, there were far more technological solutions for employment, especially those that made housekeeping easier.
This provided Americans with extra time to do things other than work.The vehicle, plane, washer and dryer, radio, moving assembly, refrigerator, garbage disposal, electric razor, instant picture, nightclub, and radio were among the technologies that helped transform America in the 1920s.Labor-saving gadgets allowed people more free leisure time as the new technologies of the 1920s transformed people's lives.Therefore, the final answer is "Option A".

Leah is making cookies to give to friends. She makes 108 cookies, and each gift box holds 16 cookies. How many gift boxes can she fill?
Answer:
6 gift boxes
Step-by-step explanation
Given the following:
Total number of cookies = 108cookies
Amount of cookies each box can hold = 16cookies
Required
Number of boxes she can fill
Number of boxes she can fill = total cookies/amount of cookies per box
Number of boxes she can fill = 108/16
Number of boxes she can fill = 6.75
This means that she can only fill 6 gift boxes with 16 cookies
Answer:

Step-by-step explanation:
(x2+4x+8)+ (2x2 +5x+9)
Answer:
[tex]\left(x^2+4x+8\right)+\left(2x^2+5x+9\right)=3x^2+9x+17[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)[/tex]
solving the expression
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)[/tex]
remove the parentheses
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)=x^2+4x+8+2x^2+5x+9[/tex]
Group like terms
[tex]=x^2+2x^2+4x+5x+8+9[/tex]
Add similar elements: x² + 2x² = 3x²
[tex]=3x^2+4x+5x+8+9[/tex]
Add similar elements: 4x + 5x = 9x
[tex]=3x^2+9x+8+9[/tex]
[tex]=3x^2+9x+17[/tex]
Therefore, we conclude that:
[tex]\left(x^2+4x+8\right)+\left(2x^2+5x+9\right)=3x^2+9x+17[/tex]
2. For the function y = 1/2x + 6, if the input is x = -4, the output is y =
A)-8
B)-2
C)1
D)4
Answer:
[tex]y = \frac{-1}{2}[/tex]
Step-by-step explanation:
Explanation:-
Given the function
[tex]y = \frac{1}{2x +6}[/tex]
Put x =-4 in given function
[tex]y = \frac{1}{2(-4) +6} = \frac{1}{-8+6} = \frac{-1}{2}[/tex]

Answer:
y = 3, TU = 6
Step-by-step explanation:
SU is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{SV}{ST}[/tex] = [tex]\frac{VU}{TU}[/tex] , substitute values
[tex]\frac{24}{4y-2}[/tex] = [tex]\frac{14.4}{2y}[/tex] ( cross- multiply )
14.4(4y - 2) = 48y
57.6y - 28.8 = 48y ( subtract 48y from both sides )
9.6y - 28.8 = 0 ( add 28.8 to both sides )
9.6y = 28.8 ( divide both sides by 9.6 )
y = 3
Then
TU = 2y = 2 × 3 = 6
If a machine that prints designs on T-shirts prints 500 shirts in 3 hours, how many hours will it take to print designs on 1,800 shirts?
500 shirts / 3 hours = 166 2/3 shirts per hour.
Divide total shirts by shirts per hour:
1800 / 166 2/3 = 10.8 hours.
Question 695271
{{{500/3=1800/x}}}

If m
is the measure of WUT?
A.32°
B.38°
C.48°
D.76°
Answer:
B
Step-by-step explanation:
A bisector splits the angle up into 2 angles that are equal to each other so all we do is set up an equation and the equation is
4x+6=6x-10
subtract 4 from each side
6=2x-10
add 10 to each side
16=2x
divide each side by 2
x=8
then we just plug in 8 to 6x=10
6(8)-10
6x8=48
48-10=38
WUT = 38

You have a bag of 15 marbles. 8 are red. 5 are blue. 2 are green. What is the probability of randomly pulling out a blue marble on the first try?
a. Because it is random, you can't calculate the probability
b.33%
c.3.3%
d.0.3 %
Answer:
33%
Step-by-step explanation:
to find the percentage of the probability you have to divide the number of diff ways of pulling out a blue marble to all the diff ways of pulling a random marble. the blue ones are 5 in total and that many are the diff ways of pulling out one, while all the diff ways of pulling a rando are equal to the total number of marbles, which is 15. so you just have to divide 5/15=1/3, whish is 33.(3)%
