Graph a triangle (XYZ) and reflect it over the line y=x to create triangle X'Y'Z'. Describe the transformation using words. Draw

a line segment from point X to the reflecting line, and then draw a line segment from point X' to the reflecting line. What do you notice about the two line segments you drew? Do you think you would see the same characteristic if you drew the line segment connecting Y with the reflecting line and then Y' with the reflecting line? How do you know

Answer:

He is the answer and btw im not sure im probably just as clueless as you so dont take my word for it.

Step-by-step explanation:

The coordinates are reversed (the coordinates X and Y have switched places, and After drawing a line segment from X to X' I could see that the points were parallel. I think that the characteristic would be the same because each point of the triangle would be effected the same way as the image has been reversed.

Kaylis [27]
The length of the diagonal will be given by:
cos θ=adjacent/hypotenuse

θ=35°
hypotenuse=h
adjacent=80 inches=6.66667 ft
thus;
cos 35=6.66667/h
h=6.66667/cos35
h=8.1385 ft
diagonal=8.1385 ft

we conclude that the table will through the door diagonally.

11. Find the product: (50z + 20)(10z + 4) ( 1 ) 12. Find the product: (88a + 80)(8a + 8) ( 1 ) 13. Find the product: (40y + zy)(
Vika [28.1K]

Answer:

11. 500z^{2}  +400z+80

12. 704a^2 + 1344a + 640

13. 160y^2 + 44zy^2  + z^2y^2

Step-by-step explanation:

11. (50z + 20)(10z + 4) = ?

Using Formula:

(a+b) (c+d) = a(c+d)+b(c+d)

50z(10z+4) + 20(10z + 4) = \\\Rightarrow 500z^{2} + 200 z+200z+80\\\Rightarrow 500z^{2} +400z+80

12. (88a + 80)(8a + 8) = ?

Using Formula:

(a+b) (c+d) = a(c+d)+b(c+d)

\Rightarrow 88a(8a+8) + 80(8a + 8)\\\Rightarrow 704a^2 + 704a + 640a + 640\\\Rightarrow 704a^2 + 1344a + 640

13. (40y + zy)(4y + zy) = ?

Using Formula:

(a+b) (c+d) = a(c+d)+b(c+d)

\Rightarrow 40y(4y + zy) + zy(4y + zy)\\\Rightarrow 160y^2 + 40zy^2 + 4y^2z + z^2y^2\\\Rightarrow 160y^2 + 44zy^2  + z^2y^2\\

Graph a line with a slope of 5 that contains the point (-2,4). <br><br>Khan Academy <br>​
weeeeeb [17]

Answer:

Graph the point (-2, 4) and then use rise over run (Up 2 and right 5)

Step-by-step explanation:

y - y1 = m(x - x1)

y - 4 = 2/5(x + 2)

y - 4 = 2/5x + 4/5

y = 2/5x + 24/5

A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
steposvetlana [31]

Answer:

4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.

Step-by-step explanation:

Let w = wooden block

Let p = plastic bricks

<u>Given the following data;</u>

Price of wooden block per pounds = $5

Price of plastic brick per pounds = $10

*Translating the word problem into an algebraic equation*

For the 10-pound mixture;

w + p = 10 .........equation 1

For the $80 mixture;

5w + 10p = 80 ..........equation 2

Solving the linear equation by using the substitution method;

Making w the subject in equation 1:

w = 10 - p .......equation 3

Substituting "w" into equation 2;

5(10 - p) + 10p = 80

Simplifying the equation, we have;

50 - 5p + 10p = 80

50 + 5p = 80

Rearranging the equation, we have;

5p = 80 - 50

5p = 30

p = \frac {30}{5}

p = 6 pounds (For the plastic brick).

To find w;

Substituting "p" into equation 3;

w = 10 - 6

w = 4 pounds (For the wooden block).
