What are the solutions to 3n-1> 8 or 4n+3 < -1 ? how would you write it in interval notation?

HELP ASAPPP PLZZZ

Step-by-step explanation:

3n - 1 > 8 or 4n + 3 < -1

3n > 9 or 4n < -4

n > 3 or n < -1

Solution set: (-∞, -1) U (3, ∞).

Direct variation

Explanation:

Given –2 + 4y + 2 = 8x.

To find the given expression –2 + 4y + 2 = 8x is direct variation or not.

If y varies directly as x, then y = kx.

If y varies inversely as x, then

⇒ –2 + 4y + 2 = 8x

Combine like terms together.

⇒ –2 + 2 + 4y = 8x

⇒ 4y = 8x

Divide both sides of the equation by 4, we get

⇒ y = 2x

Which is in the format of y = kx.

Thus y varies directly as x.

Hence, –2 + 4y + 2 = 8x is direct variation.
