Parallelogram PQRS is rotated 90° clockwise about the origin to create parallelogram P'Q'R'S'. Which rule describes this transformation? A. (x, y) --> (x, -y) B. (x,y) --> (-x, y) C. (x, y) --> (-x, -y) D. (x, y) --> (y, -x)

Answers

Answer 1

Answer: D. (x, y) --> (y, -x)

Step-by-step explanation:

The rule for a 90° clockwise rotation about the origin results in a transformation as : (x, y) --> (y, -x)

The rule for a 90° counterclockwise rotation about the origin results in a transformation as : (x, y) --> (-y, x)

For 180° rotation abiut the origin : (x, y) --> (-x, - y)

For 270°:

clockwise rotation : (x, y) --> (-y, x)

Counterclockwise rotation : (x, y) --> (y, -x)

Answers

Answer:

x = [tex]-\frac{11}{5}, 3[/tex]

y = [tex]-\frac{8}{5},1[/tex]

Step-by-step explanation:

3xy - y² = 8 -------(1)

x - 2y = 1 ------(2)

From equation (2),

x = 2y + 1

By substituting the value of x in equation (1),

3y(2y + 1) - y² = 8

6y² + 3y - y² = 8

5y² + 3y - 8 = 0

5y² + 8y - 5y - 8 = 0

y(5y + 8) - 1(5y + 8) = 0

(y - 1)(5y + 8) = 0

y = [tex]-\frac{8}{5},1[/tex]

From equation (2),

x = 2y + 1

For y = [tex]-\frac{8}{5}[/tex],

x = [tex]-2(\frac{8}{5})+1[/tex]

x = [tex]-\frac{11}{5}[/tex]

For y = 1,

x = 2(1) + 1

x = 3

Therefore, x = [tex]-\frac{11}{5}, 3[/tex]

                  y = [tex]-\frac{8}{5},1[/tex]

AND 2(3x+4) -3x=35

SHOW WORK PLEASE

Answers

Answer:

1. x=6

2. x=9

Step-by-step explanation:

1.

[tex]-2(3x+9)=-54\\-6x-18=-54\\+18 +18\\-6x=-36\\\frac{-6x}{-6} = \frac{-36}{-6}\\x=6[/tex]

2.

[tex]2(3x+4)-3x=35\\6x+8-3x=35\\3x+8=35\\-8 -8\\3x=27\\\frac{3x}{3} =\frac{27}{3} \\x=9[/tex]

Written Explanation:

1.

-2x(3x+9)=-54

-6x-`8=54 (Distributive property)

Add 18 to both sides

-6x=-36

Divide both sides by -6 (negative divided by a negative equals a positive)

x=6

2.

2(3x+4)-3x=35

6x+8-3x=35 (distributive property)

3x+8=35 (combine Iike terms and then subtract them 6x-3x=3x)

Subtract 8 from both sides

3x=27

Divide both sides by 3

x=9
