Answer:

k=9

Step-by-step explanation:

1/4k = 3 (-1/4k + 3)

Distribute the 3

1/4k = -3/4k + 9

Add 3/4 k to each side

1/4k +3/4 k = -3/4k +3/4 k + 9

4/4k = 9

k =9

I NEED HELP ASAP!<br><br> 7x-3y= 6; х= 3
marysya [2.9K]

Answer:

If you are looking for y it's 5

Step-by-step explanation:

Plug in 3 for x

7(3) -3y = 6

21 - 3y = 6

subtract 21 from both sides

-3y = - 15

divide by three from both sides

y = 5

Solve x2 – 8x 41 = 0 for x. x = –4 ± 5i x = 4 ± 5i
Ede4ka [16]
X^2 - 8x + 41 = 0
x = \frac{-(-8)\pm\sqrt{(-8)^2-(4\times41)}}{2}=\frac{8\pm\sqrt{64-164}}{2}\\=\frac{8\pm\sqrt{-100}}{2}=\frac{8\pm10i}{2}=4\pm5i

If point U is reflected across the x = -3, what are the coordinates of its reflection image?
Elena L [17]

The coordinates of U after the reflection are: (-5, -3)

<h3>How to get the coordinates after the reflection?</h3>

By looking at the graph, we can see that the coordinates of point U are:

U = (-1, -3)

And we want to reflect it across the line x = -3.

Notice that because this is a vertical line, the y-component does not change by the reflection. Only changes the x-component, such that the distance between the original coordinates and the final coordinates to the line don't change.

The original x-component is x = -1, the distance to the line is:

d = |-3 - (-1)| = 2 units.

Then the new x-component will also be at 2 units of the line, but in the other direction:

new x-component: x = -3 - 2 = -5

The coordinates of U after the reflection are:

(-5, -3)
