Answer:

C. x+8=3x

Step by step explanation:

First, subtract 8 from both sides of the equation

x+8=3x

x+8-8=3x-8

Then, simplify it by subtracting again

x+8-8=3x-8

x=3x-8

Then, subtract 3x from both sides of the equation

x=3x-8

x-3x=3x-8-3x

Then, simplify by combining the terms

x-3x=3x-8-3x

-2x=3x-8-3x

-2x= -8

Then, divide both sides of the equation by the same term

-2x= -8

-2x/-2 = -8/-2

Then, simplify by cancling terms that are in both the numerator and denominator

-2x/-2 = -8/-2

x= -8/-2

Finally, divide the numbers

x= -8/-2

x=4

And that's your answer! :)

Find the coordinates of n after a 90 degrees clockwise rotation around the origin

Ket [755]

Answer:

270 degrees

Step-by-step explanation:

If you want a positive number, you can say that the origin is 360 degrees. Then, being it's moving clockwise, subtract 90 degrees from 360 degrees. That will give you 270 degrees.

If you want a negative answer, you could simply say that the origin is 0 and subtract 90 from that giving you -90.

Odds are you should go with 270.

What is 3x^2-2n-5=0 please help me!!!

expeople1 [14]

The answer to your question is:
It is a quadratic equation in 'x', with 'n' mistakenly typed in the second term..

Although you didn't ask for the solutions to the equation, I'm already here
so I might as well go through it and find them:

3x² - 2x - 5 = 0

In terms of the generic quadratic formula:
A = 3
B = -2
C = -5

Plug those into the quadratic formula, and you discover that

x = -1
and
x = ⁵/₃

The graph of a quadratic function contains (4,-64) and it's vertex is at the origin.write an equation for this function.

lesya692 [45]

Answer:

Step-by-step explanation:

Not sure what form you need this in, but it really doesn't matter, as you'll see in the final equation. I used the vertex form and solved for a:

$y=a(x-h)^2+k$

We are given the vertex (h, k) as the origin (0, 0), and we have a point that the graph goes through as (4, -64). That's our x and y. Plugging in what we have:

$-64=a(4-0)^2+0$ gives us

-64 = 16a and

a = -4. That means that the quadratic equation is

$y=-4x^2$ which is both vertex form and standard form here, no difference.
