solving the system of equation x--2y=5 and 3x+15=-6

Answers

Answer 1

x=-7

y=-6

Further Explanation  

One variable linear equation is an equation that has a variable and the exponent number is one. Can be stated in the form:

ax=b  ax + b = c,

where a, b, and c are constants, x is a variable

Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one

Can be stated in the form:

ax+by=c  

x, y = variable

x--2y=5 ⇒ equation 1

3x+15=-6 ⇒ equation 2

Solve equation 2 for x

[tex]\tt 3x+15=-6\\\\3x=-21\\\\x=-7[/tex]

Input x to equation 1 for y

[tex]\tt -7-2y=5\\\\-2y=12\\\\y=-6[/tex]

g How can a magnetic reversal pattern be used to determine the age of a region of ocean floor without the need for additional isotopic dating

Answers

Answer and Explanation:

About two-thirds of the Earth's surface lies beneath the oceans. The depths of the open ocean were mostly a matter of speculation before the 19th century. Most people thought ocean floor was flat and featureless. In the early 16th century, a few navigators found that the open ocean can differ considerably in depth by taking soundings with hand lines, which shows that the ocean floor was not as flat as it believed.

At the beginning of the 1950s, scientists used magnetic instruments adapted from airborne devices to recognize odd magnetic variations across the ocean developed during World War II to detect submarines. They found that the iron-rich and volcanic rock make up the ocean floor-- contains a strongly magnetic mineral and can distort compass readings. In the early 18th century, this distortion was recognized by Icelandic mariners. Magnetite gives measurable magnetic properties; these magnetic variations help to study the deep ocean floor.

Whose concept of the balance of power in politics led to the conviction that three equal and coordinate branches of government should be established

Answers

MONTESQUIEU

Montesquieu brought about the concept of balance in politics that led to the conviction that three equal and coordinate branches of government should be established.

trias politica means seperation of power,these terms were coined by Montesquieu (Charles-Louis de Secondat, baron de La Brède et de Montesquieu).

He principally sourced the principle of seperation of powers. Montesquieu asserted that to promote liberty most effectively,that these three powers must be separated and made to act independently. He took the idea from the view that the Roman republic separated their powers and for that fact,no one could usurp a power that is complete.

Montesquieu came to the conclusion that the best form of government is one that the legislative, executive and the judiciary powers/arm of government are seperate in operation and each one keeps the other in check to avoid any of them from becoming too powerful,just as in the Louis XIV monarchy, would further result in despotism.

   Number of wins = 44 games

Unknown:

The ratio of wins to losses = ?

Solution:

The ratio of wins to losses;

            Number of wins :  Number of losses

Number of losses  = Number of games - Number of wins = 82 - 44 = 38

 The ratio is;

                      44 : 38

what geologic processes change pieces of rocks, minerals, and other material into sedimentary rock?​

Answers

Answer:

Una roca preexistente expuesta en la superficie de la tierra pasa por un Proceso Sedimentario (erosión o intemperismo, transporte, depósito, compactación y diagénesis) con el que llega a convertirse en una roca sedimentaria; a esta transformación se le conoce como litificación.

Igneous, metamorphic, and sedimentary rocks are the three basic types of rock. Crystallization, metamorphism, erosion, and sedimentation are the three processes that turn one rock into another.

Weathering is the answer type of process.

The geological processes

Erosion, weathering, dissolution, precipitation, and lithification are the most major geological processes that lead to the formation of sedimentary rocks.

The actions of wind and rain, which gradually break down huge boulders into smaller ones, are included in erosion and weathering.

By undergoing one or more of these transformations, every rock can become any other rock. The rock cycle is the result of this.

Two characteristics of talus

Answers

Answer:

Explanation:

Abstract

Vegetation‐covered relict talus slopes are widespread at the base of glacially steepened rockwalls in Scotland. Investigations carried out on two such slopes, one in the An Teallach massif in Wester Ross, the other on the flanks of West Lomond, Fife, suggest that these slopes accumulated as a result of rockfall in the interval between the retreat of the Late Devensian ice sheet and the end of the Loch Lomond Stadial. Other processes (basal erosion, avalanches and debris flow) were apparently not effective in modifying these slopes during accumulation. During the Holocene, however, rockfall accumulation at these sites has been almost negligible. Present‐day rockwall retreat rates average 0.015mm y‐1 (excluding infrequent large‐scale falls) and are thus low in comparison with rates measured in other environments or calculated for the Loch Lomond Stadial. The main processes operating during the Holocene on these slopes are slope failure, debris flow, gullying and soil creep.

Golgi apparatus, packages proteins into vesicles is the organelle is the line pointing. Thus, option (a) is correct.

What is organelle?

An organelle is a subcellular structure that, like an organ in the body, has one or more distinct duties to do in the cell. These are structures found in cells that execute many types of metabolic processes; examples include the ribosome and the Golgi apparatus.

The Golgi apparatus is in charge of packing and transporting biomolecules like protein and lipids to their final destination for a variety of reasons. This guarantees that resources are distributed evenly across the cell. The form resembles a sequence of stacked flat cisternae.

As a result, Golgi apparatus, packages proteins into vesicles is the organelle is the line pointing. Therefore, option (a) is correct.
