Which series of transformations results in the image being congruent to the pre-image?

2 answers:

7 0

To be congruent only translation, rotations and reflections are allowed
1)
(x, y) → (2x, y)=scale->not congruent
(x, y) → (x , y + 7)
(x, y) → (–x, –y)
2)
(x, y) → (x – 5, y)=translation
(x, y) → (x, –y)=reflection
(x, y) → (0.75x, 0.75y)=scale->not congruent
3)
(x, y) → (–x, y)=reflection
(x, y) → (3x, 3y)=scale->not allowed
(x, y) → (x – 9, y)
4)
(x, y) → (–x, –y)=reflection
(x, y) → (x + 4, y)=transformation
(x, y) → (x, y – 1)=transformation
->is congruent

so 4) is a series of transformations with a congruent after image

Find the solution using the Quadratic Formula. (show work) 2x + 8x+ 5 = 0 a. 47 ſ6 b. -27 56 c. -2± √3

Nookie1986 [14]

Answer:

The roots of the equation for the given quadratic equation is $-2\pm \frac{\sqrt{6}}{2}$ .

Step-by-step explanation:

Given quadratic equation as :

2 x² + 8 x + 5 = 0

The roots of the quadratic equation ax² + bx + c = 0 as can be find as :

x = $\frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}$

x = $\frac{-8\pm \sqrt{8^{2}-4\times 2\times 5}}{2\times 2}$

or, x = $\frac{-8\pm \sqrt{64-40}}{4}$

Or, x = $\frac{-8\pm \sqrt{24}}{4}$

Or, x = $\frac{-8\pm 2\sqrt{6}}{4}$

∴ x = $-2\pm \frac{\sqrt{6}}{2}$

Hence The roots of the equation for the given quadratic equation is $-2\pm \frac{\sqrt{6}}{2}$ . Answer

Let f(x) = 1/x+2 and g (x) = 1/x-3. Find (f/g) (x). Assume all appropriate restrictions to the domain. help!!!!

DanielleElmas [232]

Answer:(f/g)(x)=(1+2x)/(1-3x) where x<>0

Step-by-step explanation:

f(x)= 1/x+2= (1+2x)/x , x<>0

g(x)=1/x-3=(1-3x)/x , x<>0

=>f(x)/g(x)= (1+2x)/(1-3x) , x<>0

it's C because whenever it says and you're supposed to multiply always remember that :) = (which means area ofc) you're finding the so you multiply 16x8 and the you get your answer (: ignore the 640 you just focus on the 16 and 8 ok? 16x8=128! :))
