I need in form of y=mx+b Thank you!
Answers
Answer:
y = -2x + 3
Step-by-step explanation:
Let equation of the line be y = mx + b
Since the line is perpendicular to y = 1/2x - 10,
product of the gradient of both lines = -1
therefore,
1/2 x m = -1
m = -2
since it passes through (4, -5),
sub (4, -5):
-5 = -2(4) + b
b = 3
therefore, equation of the line is y = -2x + 3

Please define the following terms:
mercantilism, import, export, enumerated article, legislature, indentured servant, Navigation Acts, Dominion of New England, English Bill of Rights.
Answers
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

Abby takes a ride-sharing service to ride from her home to the mall. The ride-sharing service charges $1.75 per mile plus a one-time charge of $5.00.
Which equation can be used to find y, the total cost of the ride, given x represents the number of miles of the ride?
(A.) y=1.75x−5
(B.) y=1.75(x+5)
(C.) y = 1.75x + 5
(D.) y = 5x + 1.75
Answers
Answer:
c)
Step-by-step explanation:
$5.00 is a one time charge but $1.75 is per mile and x represents the number of miles.
The equation can be used to find y is option (C.) y = 1.75x + 5
Given that,
The ride-sharing service charges $1.75 per mile plus a one-time charge of $5.00.Equation:Here we present the equation for determining the y.
y=1.75(x+5)

How many miles does the truck travel each hour?
A. 3 miles
B. 60 miles
C. 6 miles
D. 40 miles
Answers
40miles/hour
Answer is D
The truck travels D) 40 miles per hour
What is the speed of an object?Speed of an object is given by the distance travelled divided by time taken to traverse that distance , S = Distance/ time
Given here, distance = 2,400 miles and time taken= 60 hours
therefore speed = 2400/60
= 40 miles per hour
Hence, the truck travels 40 miles every hour.
