Help. I have a D in this class.
postnew [5]

Answer:

y = (x - 4)² - 26

Step-by-step explanation:

To complete the square, all we need to do is take term -8x, and add enough to make the equation come out to the square of half that.  Half of -8 is -4, so we need to add 26 to the equation to end up at 16:

y = x^2 - 8x - 10\\y + 26 = x^2 - 8x + 16\\y + 26 = (x - 4)^2\\y = (x - 4)^2 - 26

Giving us the final result

Which sequence of transformations produces an image that is not congruent to the original figure?
stiks02 [169]
D

Translations, Reflections, and Rotations are transformations that result in a congruent figure.

Dilations on the other hand don't. They change the size of the figure, which means the transformed figure is not congruent to the original.

Find f^-1(x) <br><br> A<br> B<br> C<br> D
inna [77]

<u><em>Answer:</em></u>

D. f⁻¹(x) = 2x + 10

<u><em>Explanation:</em></u>

<u>The given is:</u>

f(x) = \frac{1}{2}x - 5

<u>To find the inverse, follow the below procedures:</u>

<u>1- Convert f(x) to y. </u>

<u>This will give:</u>

y = \frac{1}{2} x - 5

<u>2- Swap the x and y variables.</u>

<u>This will give:</u>

x = \frac{1}{2}y - 5

<u>3- Solve for y.</u>

<u>This will give:</u>

x = \frac{1}{2}y - 5\\ \\ \frac{1}{2}y = x+5\\ \\ y = 2x+10

<u>4- Replace the y in the above step with f⁻¹(x).</u>

<u>This will give us:</u>

f⁻¹(x) = 2x + 10

Hope this helps :)
