Answer:

<em></em>(13,-23)<em></em>

Step-by-step explanation:

Given

Translation: (x,y) -> (x-4,y+15)

Required

Determine the pre-image of (9,-8)

In (9,8)

x = 9 and y = -8

So:

(x,y) -> (x-4,y+15)

Becomes

(9,8) ->(x-4,y+15)

By comparison:

x - 4 = 9

y + 15 = 8

Solving for (x):

x - 4 = 9

x = 9 + 4

x = 13

Solving for (y):

y + 15 = -8

y = -8 - 15

y = -23

<em>Hence, the pre -image has a coordinate of </em>(13,-23)<em></em>

ABCD is a quadrilateral inscribed in a circle, as shown below:
german

Answer:

  • A. (x + 16) + (6x − 4) = 180

Step-by-step explanation:

Inscribed quadrilateral has opposite angles supplementary.

<u>So</u>

  • m∠A + m∠C = 180°

or

  • m∠B + m∠D = 180°.

<u>Since</u>

  • m∠A = x + 16,
  • m∠B = x,
  • m∠C = 6x - 4,
  • m∠D = 2x + 16

we can use either pair of angle measures to work out the value of x and then find the value of each angle.

<u>We can verify the first option is the only correct one.</u>

  • m∠A + m∠C = 180°
  • (x + 16) + (6x − 4) = 180
