Select all equations that can result from adding these
two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
(Select all that apply)
Answer:
Step-by-step explanation:
x + y = 12 ---------------(1)
3x - 5y = 4 --------------(2)
(1)*5 + (2) * 1 then,
5x + 3x = 60 + 4
8x = 64
x = 64/8
x = 8
from (1), 8 + y = 12
y = 4
apply(x,y)=(8,4) to these function.
-2x-4y = -32 no
-2x+6y=8 yes
like this
The required expression after the addition of the equations is 4x - 4y = 16, and the expression after the subtracting of the equations is -2x +6y = 8.
Given that,
To select all equations that can result from adding these two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
Here,
Addition
x + y = 12
+ 3x - 5y = 4
--------------------
4x - 4y = 16
Subtraction,
x + y = 12
- (3x - 5y = 4)
--------------------
x + y = 12
- 3x + 5y = -4
---------------------
-2x + 6y = 8
Thus, the required expression after the addition of the equations is 4x - 4y = 16, and the expression after the subtracting of the equations is -2x +6y = 8.

Ziann’s weekly earnings were proportional to the number of hours she worked. This table shows the number of hours Susan worked and the amount she earned.
How much money did Ziann earn per hour?
Answer:
Can't answer.
Step-by-step explanation:
We know that Ziann's earnings were proportional to the hours she worked, but the table shows how much Susan earned, so we don't know how much Ziann earned. We are not told that Ziann and Susan are the same person.
Susan's earnings:
$47.50/(5 hours) = $9.50/hour
According to the table, Susan earned $9.50 per hour.

Please define the following terms:
mercantilism, import, export, enumerated article, legislature, indentured servant, Navigation Acts, Dominion of New England, English Bill of Rights.
Answer:
Mercantilism is an economic policy that is designed to maximize the exports and minimize the imports for an economy. It promotes imperialism, tariffs and subsidies on traded goods to achieve that goal
Import is to bring in (merchandise, commodities, workers, etc.) from a foreign country for use, sale, processing, reexport, or services.
Export is to ship (commodities) to other countries or places for sale, exchange, etc.
enumerated article is under the English navigation Acts, those commodities that could be shipped only to England or other English colonies; originally included sugar, tobacco, cotton, and indigo.
legislature is a deliberative body of persons, usually elective, who are empowered to make, change, or repeal the laws of a country or state; the branch of government having the power to make laws, as distinguished from the executive and judicial branches of government.
An indentured servant or indentured laborer is an employee (indenturee) within a system of unfree labor who is bound by a signed or forced contract (indenture) to work without pay for the owner of the indenture for a period of time
The Navigation Acts, or more broadly the Acts of Trade and Navigation, was a long series of English laws that developed, promoted, and regulated English ships, shipping, trade, and commerce between other countries and with its own colonies.
The Dominion of New England in America was an administrative union of English colonies covering New England and the Mid-Atlantic Colonies.
The English Bill of Rights was an act signed into law in 1689 by William III and Mary II, who became co-rulers in England after the overthrow of King James II. The bill outlined specific constitutional and civil rights and ultimately gave Parliament power over the monarchy

This table shows the relationship between x and y.
btw i put that on accident
Answer:
C) 54.5
Step-by-step explanation:
to find the constant of this proportional x and y table;
first divide y by x.
eg. 163.5 divided by 3, which results in 54.5
next, to confirm this is our answer, we need to divide y by x once more.
eg. 327 divided by 6, which also results in 54.5
