(3, −6), and (3, −8) at its vertices. Are the triangle and its transformation congruent? Why or why not?
A. Yes, the transformation is a 90° clockwise rotation.
B. No, the transformation is a 180° clockwise rotation.
C. Yes, the transformation is a 270° clockwise rotation.

Answer with explanation:

Vertices of Triangle are (7, 6), (6, 3), and (8, 3) .

When the triangle is transformed that is rotation has taken place and the  coordinates of vertices of Image are (6, −7), (3, −6), and (3, −8).

When you will compare Pre image and Image

1.⇒ Rotation in clockwise direction has taken place to get the Image.

2.⇒Pre Image is in First Quadrant, and Image is in fourth Quadrant

Among the four transformation , Reflection, Rotation, Translation and Dilation , in first three that is, Reflection, Rotation,and Translation Preimage and Image are Congruent , while in Dilation the two, Preimage and Image are Similar.

So , Yes the two triangles are Congruent.

⇒Option A: Yes, the transformation is a 90° clockwise rotation.

The multiplication property of equality could be used to solve which of the following equations?
Evgesh-ka [11]

Multiplication property of equality can be used to solve: \frac{b}{-2} = 18

Step-by-step explanation:

First of all, lets define the multiplication property of equality

The multiplication property of equality states that if one side of an equation is multiplied with any number the other side is also multiplied with the number.

Given equations are:

(x+2)(x-2) = 0\\m+7 = -12\\\frac{b}{-2} = 18\\-3+y = 7

By observing the equations we can see that only third equation has a fraction in it so it has to be multiplied with -2 for solution

\frac{b}{-2} * - 2 = 18*-2\\b = -36

Hence,

Multiplication property of equality can be used to solve: \frac{b}{-2} = 18

Y=19x+19b solve for b in the literal equation
Ymorist [56]
Y=19x+19b
To solve for b you first need to subtract 19x from both sides giving you:

y-19x=19b


Then, divide by 19 on both sides to get

(y/19)-x=b

So b=(y/19)-x

Hope this helps!!! Follow me :)

What is the solution of the following systems of equations? y = 1/2x <br> y = -x -3
SVEN [57.7K]

Answer:

<em>x = -2,  y = -1</em>

Step-by-step explanation:

<u>System of Equations</u>

Solve the system:

y = 1/2x

y = -x - 3

Multiplying the first equation by 2:

2y = x

Substituting x in the second equation:

y = -2y - 3

Adding 2y:

3y = -3

y = -3/3

y = -1

And x = 2*(-1) = -2

Solution: x = -2,  y = -1
