Find the translation rule and the scale factor of the dilation that transforms Ol to Ol'.
lisov135 [29]

Answer:

  C  (x, y) -> (x + 7, y + 8); scale factor = 3

Step-by-step explanation:

The translation can be found by subtracting the coordinates of the original center from those of the center of the image. The scale factor will be the ratio of the radii.

__

<h3>translation</h3>

We note the center coordinates are I(-3, -6) and I'(4, 2). Then the translation is ...

  I' -I = (4, 2) -(-3, -6) = (4 +3, 2 +6) = (7, 8)

  (x, y) ⇒ (x +7, y +8)

<h3>scale factor</h3>

The radius of each circle can be found by counting the grid squares from the center to the circle. It works best to do this along a horizontal or vertical line.

The radius of circle I is 2; the radius of circle I' is 6. The scale factor is ...

  scale factor = 6/2 = 3

Use the functions f(x) = 4x − 5 and g(x) = 3x + 9 to complete the function operations listed below.
alukav5142 [94]
A) (f+g)(x)=f(x)+g(x)=(4x-5)+(3x+9)=7x+4
B) (f*g)(x)=f(x)*g(x)=(4x-5)(3x+9)=12x^2+21x-45
C) f(g(x)) = 4(3x+9)-5 = 12x+31

Please help, this is due today:
Marina86 [1]

Answer:

x = 17

Step-by-step explanation:

∠ DCE = ∠ ACE ( vertically opposite angles )

The sum of the 3 angles in a triangle = 180° , then

∠ DCE = 180° - (100 +x) = 180 - 100 - x = 80 - x

∠ ACE = 180 - (49 + 4x) = 180 - 49 - 4x = 131 - 4x

Equating the 2 angles

80 - x = 131 - 4x ( add 4x to both sides )

80 + 3x = 131 ( subtract 80 from both sides )

3x = 51 ( divide both sides by 3 )

x = 17
