Answer: choice D) translation 6 units to the right

The black triangle slides over 6 units to the right to line up perfectly with the blue triangle. In other words, every point on triangle A will slide over 6 units to the right to line up with its corresponding point on triangle A'. Both triangles are congruent (same shape and size).

****BRAINLIEST GOES TO THE FIRST CORRECT ANSWER****
Drupady [299]

The two equations are vertical angles, which mean they are equal.

Set each equation to equal each other and solve for x.


3x-3 = 6(x-10)

Simplify the right side:

3x-3 = 6x-60

Subtract 3x from each side:

-3 = 3x - 60

Add 60 to each side:

57 = 3x

Divide both sides by 3:

x = 57 / 3

x = 19

Solve for x in the equation x^2-4x-9=29? x=2+/- squareroot 42 x=2+/-squareroot 33 x=2+/-squareroot 34 x=4+/-squareroot 42
jeka57 [31]
For this case what we must do is to use the formula of the resolvent in the following way:
 x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
 Where,
 a = 1
 b = -4
 c = -38
 Substituting the values:
 x = (- (- 4) +/- root ((- 4) ^ 2 - 4 * 1 * (- 38))) / (2 * 1)
 x = (4 +/- root (168)) / 2
 x = (2 +/- root (42))
 Answer:
 x = 2 +/- squareroot 42

Why is the quotient -100/(-5) the same as the quotient 100/5
Tatiana [17]

Answer:The quotient of -100 and -5  is the same as the quotient of 100/5 because if you divide a negative number by a negative number, you will get a positive number and the same way if you divide a positive number by a positive number you will get a positive number.

Step-by-step explanation:

-100/-5 = 20

100/5 = 20
