the graph below represents the liner equation y equals 1 and 1/2 x -3 A second linear equation is represented by data in the tab
fomenos

Answer:

C. (2, -2)

Explanation:

Given:

y = \frac{1}{2}x - 3 ----› Equation 1

Use the table to generate equation two of the system.

First, find the slope (m), and y-intercept (b).

Using two pairs, (0, 0) and (2, -2),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 0}{2 - 0} = \frac{-2}{2} = -1

y-intercept (b) = 0 (i.e  the value of y when x = 0)

Substitute m = -1, and b = 0 in y = mx + b

Thus:

y = (-1)(x) + 0

y = -x ----› Equation 2.

✔️Solve for x by substituting y = -x in equation 1

y = \frac{1}{2}x - 3

-x = \frac{1}{2}x - 3

Add 3 to both sides

-x + 3 = \frac{1}{2}x - 3 + 3

-x + 3 = \frac{1}{2}x

Multiply both sides by 2

(-x + 3) \times 2 = \frac{1}{2}x \times 2

-2x + 6 = x

Collect like terms

-2x - x = -6

-3x = -6

Divide both sides by -3

x = 2

✔️Substitute x = 2 in equation 2.

y = -x

y = -2

Therefore the solution to the system of equations would be:

(2, -2)

If I describe a murder, where exactly in the description do I find the actual evil in it? Is it in the events themselves and in
Anton [14]

Answer:

The evil in the murder will definitely lie in the action itself.

Explanation:

Death is the expected biological destination of all living thing.

Living things are described as such because they have the characteristic of being able to die.

Every living thing especially humans and in some cases animals and plants have the right to follow through this course (the Life-Death Continuum) naturally. Any event which intentionally circumvents this naturally transition without any moral/good reason (such as murder) is considered evil.

The event is not evil. Death is a necessary part of the cycle of life and is important for life to continue.

For example, cells die for new ones to be born. We harvest plants and plant new ones etc.

To adopt a normative approach alone would down-play the requirement and rights to life for as long as it should last.    

Cheers!

Which of the following situations is descriptive of the existence of a negative externality. Vernon studies for his biology test
liberstina [14]

Answer: I think it is Nancy is in the library looking for a book. She is talking to herself and consequently disturbs a few people in the library.

Explanation:

There are good externalities and bad externalities in economics. A good externality is when for example a farm of flowers is situated next to a producer of honey. The farmer benefits from the polinization of his flowers and the honey producer from the pollen and nectar that bees take from the flowers to produce honey. A negative externality is something like in the case mentioned of Nancy who reads aloud and disturbs other people in the library and doesn't let them read peacefully.

How did this invention help the Qin to conquer the rest of China?
Ber [7]

The Qin introduced common coinage, meaning a form of ´fiat´ currency backed by the central government. It was called a ´ban liang´, and they could be issue by local nobles as well as by the emperor. A system of coinage is important for the unification of a massive empire because it facilitates trade and the recollection of revenue for the central government. As such, it becomes easier to raise a common army, which is essential for unification of different warring states.
