The parallelogram is reflected across the line y = x. Which of the following are coordinates of a vertex of the image?
Korvikt [17]

Answer:

A'(1,-5)

Step-by-step explanation:

The coordinates of the given quadrilaterals are

A(-5,1),B(-4,3),C(-2,1),D(-3,-1)


The reflection in the line y=x has the mapping,

(x,y)\rightarrow(y,x)


We just have to swap the coordinates.


This implies that,


A(-5,1)\rightarrow A'(1,-5)


B(-4,3)\rightarrow B'(3,-4)


C(-2,1)\rightarrow C'(1,-2)


D(-3,-1)\rightarrow D'(-1,-3)


Therefore the correct answer is A.

A'(1,-5)

Answer: 82.5 - x = R sorry if I am wrong

Step-by-step explanation:

1. We know all the angles in a triangle add up to 180 degrees.

<em>180 = x + x + 15 + R</em>

2. Combine like terms

<em>180 = 2x + 15 + R</em>

3. Subtract 15 from both sides

<em>165 = 2x + R</em>

4. Divide both sides by 2

<em>82.5 = x + R</em>

5. Subtract x from both sides

<em>82.5 - x = R</em>

1. Solve the following equation by factoring: 4x2 + 12x + 9 = 0
Luden [163]

Answer:

x = -3/2

Step-by-step explanation:

4x² + 12x + 9 = 0

Use AC method to factor, or recognize the perfect square.

(2x + 3)² = 0

2x + 3 = 0

x = -3/2

A. 5x - 2 = 8<br>b. 4x - 3= 2x + 9<br>C. 6x + 3 = 2x + 8​
Elena L [17]

Answer:

a) x=2

b)x=12

c)x=5/4

Step-by-step explanation:

a)5x-2=8

5x=8+2

5x=10

x=2

b)4x-3=2x+9

4x-2x=9+3

2x=12

x=6

c)6x+3=2x+8

6x-2x=8-3

4x=5

x=5/4

Proof:

a)5x-2=8

5(2)-2=8

10-2=8

8=8

b)4x-3=2x+9

4(12)-3=2(12)+9

48-3=24+9

45=45

c)6x+3=2x+8

6(5/4)+3=2(5/4)+8

30/4+3=10/4+8

15/2+3=5/2+8

10.5=10.5

Hope this helps ;) ❤❤❤
