Answer:

A, B, E

Step-by-step explanation:

Permutations are involved when order matters, as in lane assignment, passwords, and seating charts.

When the end result is a "group of 10 students", "3 employees", or "4 cashiers", clearly order does not matter. One student, employee, or cashier is as good as another in these cases.

Given:

The equation is

$\left(z+\dfrac{6}{7}\right)+\dfrac{2}{14}=-1$

To find:

The solution of the given equation.

Solution:

We have,

$\left(z+\dfrac{6}{7}\right)+\dfrac{2}{14}=-1$

It can be written as

$\left(z+\dfrac{6}{7}\right)+\dfrac{1}{7}=-1$

$\left(z+\dfrac{6}{7}\right)=-1-\dfrac{1}{7}$

Multiply both sides by 7.

$7z+6=-7-1$

$7z+6=-8$

$7z=-8-6$

$7z=-14$

Divide both sides by 7.

$z=\dfrac{-14}{7}$

$z=-2$

Therefore, the value of z is -2.

Summer is approaching, so workers at the Lawrenceville Community Center are filling the pool. The volume of water in the pool x

Vanyuwa [196]

Answer:

The pool is being filled

Step-by-step explanation:

The function definition tells you ...

f(5) = the volume of water in the pool 5 minutes after they start

f(10) = the volume of water in the pool 10 minutes after they start

So, the inequality ...

f(5) < f(10)

means the volume of water in the pool 10 minutes after they start is greater than it is 5 minutes after they start. In short, <em>they are filling the pool</em>.

What are the solutions to the equation y2 – 1 = 48?

Furkat [3]

${y}^{2} - 1 = 48 \\ {y}^{2} = 49 \\ y = \sqrt{49} \\ y = - 7 \: or \: 7$

${y}^{2} - 1 = 24 \\ {y}^{2} = 25 \\ y = \sqrt{25} \\ y = - 5 \: or \: 5$

Hope this helps. - M
