-2x - 18 = 611-2x) + 4x

Serhud [2]

Answer:

x = (-629)/4

Step-by-step explanation:

Solve for x:

-2 x - 18 = 4 x - 2 x + 611

4 x - 2 x = 2 x:

-2 x - 18 = 2 x + 611

Subtract 2 x from both sides:

(-2 x - 2 x) - 18 = (2 x - 2 x) + 611

-2 x - 2 x = -4 x:

-4 x - 18 = (2 x - 2 x) + 611

2 x - 2 x = 0:

-4 x - 18 = 611

Add 18 to both sides:

(18 - 18) - 4 x = 18 + 611

18 - 18 = 0:

-4 x = 611 + 18

611 + 18 = 629:

-4 x = 629

Divide both sides of -4 x = 629 by -4:

(-4 x)/(-4) = 629/(-4)

(-4)/(-4) = 1:

x = 629/(-4)

Multiply numerator and denominator of 629/(-4) by -1:

Answer: x = (-629)/4

Describe the sequence of transformations from quadrilateral ABCD to A'B'C'D A: -8,8 B: 8,-2 C: 4,-8 D: 4,-2 A': 2,-10 B': 8,-10

butalik [34]

Answers:

See below

Step-by-step explanation:

First transformation

Reflection about the line y = 6.

This inter-converted Points A and C and Points B and D.

The coordinate transformations were (Fig. 1):

A: (-8, 8) ⟶ (-8, 4)

B: (-2, 8) ⟶ (-2, 4)

C: (-8, 4) ⟶ (-8, 8)

D: (-2, 4) ⟶ (-2, 8)

Second transformation

Translation 10 units to the right and 14 units down.

The coordinate transformations were (Fig. 2):

A: (-8, 4) ⟶ (2, -10)

B: (-2, 4) ⟶ (8, -10)

C: (-8, 8) ⟶ (2, -6)

D: (-2, 8) ⟶ (8, -6)

The transformations were:

Reflection about the line y = 6
Translation 10 units to the right and 14 units down
