Jolene is making a line graph showing that the cost of grain is proportional to the number of pounds purchased. Jolene will plot the number of pounds on the x-axis and the cost in dollars on the y-axis. The coordinates Jolene graphs are shown in the table.
Which coordinate represents the unit rate, in dollars per pound of grain, and why?
Pounds Cost (in dollars)
1.0 0.25
4.0 1.00
Create an equation to represent the cost, y, in dollars, for x pounds of grain.
Answer:
a. [tex](1,0.25)[/tex]
b. [tex]y = 0.25x[/tex]
Step-by-step explanation:
Given
The data in the table
Solving (a): The coordinate that represents the unit rate
The unit rate is when its 1 pound
This is so because the unit rate is dollars per pounds.
Hence, the coordinate is [tex](1,0.25)[/tex]
Solving (b): Equation of the graph
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where:
[tex](x_1,y_1) = (1,0.25)[/tex]
[tex](x_2,y_2) = (4,1.00)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{1.00 - 0.25}{4 - 1}[/tex]
[tex]m = \frac{0.75}{3}[/tex]
[tex]m = 0.25[/tex]
The equation is then calculated as thus:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - 0.25 = 0.25(x - 1)[/tex]
[tex]y - 0.25 = 0.25x - 0.25[/tex]
Make y the subject
[tex]y = 0.25x[/tex]
Hence, the equation of the graph is: [tex]y = 0.25x[/tex]

The Alien Enemies Act of 1798 allowed the president to deport noncitizens considered dangerous. allowed the president to ignore laws he believed unconstitutional. made immigrants wait longer before becoming citizens. made it a crime to criticize the federal government.
Answer: Allowed the president to deport noncitizens considered dangerous.
Step-by-step explanation:
The Alien Enemies Act was part of the Alien and Sedition Acts which were passed through Congress by the Federalist party under President John Adams during a time when they feared going to war with France. These acts were meant to prevent support of the French amongst immigrants who habored French sentiments.
The Alien Enemies Act gave the President the power to arrest and then deport noncitizens of the US or rather citizens of other countries that the US were at war with as they were considered dangerous.

Item 3 Find the distance from the point (-2,6) to the line y=x-8 . Round your answer to the nearest tenth
Answer:
16 units
Step-by-step explanation:
The distance of the point P ( -2 , 6 ) to the line y = x - 8 is given by the equation D = 8√2 units = 11.3 units
What is the distance from the point to a line?The shortest distance between any two points on an infinite straight line is called the distance from a point to a line. The length of the line segment connecting the point to the closest point on the line is the perpendicular distance between the point and the line.
Let the equation of line be = Ax + By + C = 0
Let the point be P ( x₀ , y₀ )
Distance of a point to line D = | Ax₀ + By₀ + C | / √ ( A² + B² )
Given data ,
Let the distance be represented as D
Now , let the point be P = P ( -2 , 6 )
Let the equation of line be A
The value of A is
y = x - 8
Subtracting y on both sides of the equation , we get
x - y - 8 = 0 be equation (1)
Now , Distance from a point to line D = | Ax₀ + By₀ + C | / √ ( A² + B² )
Substituting the values in the equation , we get
Distance from a point to line D = | 1 ( -2 ) + ( -1 ) ( 6 ) - 8 | / √ ( 1² + 1² )
On simplifying the equation , we get
Distance from a point to line D = | -2 - 6 - 8 | / √2
Distance from a point to line D = | -16 | / √2
Distance from a point to line D = 16/√2
Multiply the numerator and denominator of the fraction by √2 , we get
Distance from a point to line D = 16√2 / 2
Distance from a point to line D = 8√2 units
Hence , the distance is 8√2 units = 11.3 units

Kristy asks Lonnie to think of a number add it with 3 to it multiply the sum by 2 and the subtract 6. let (n) stand for Lonnies starting number. which expression represents Lonnies final number
Answer:
2(n + 3) - 6 is the expression that represents the final number.
Step-by-step explanation:
Answer: the expression becomes 2(x +3) - 6.
Let the number be x. Then according to the question,
Step 1 :- Adding 3
=> x + 3
Step 2 :- Multiply the sum by 2
=> 2×(x + 3)
Step 3 :- Subtract 6
=> 2(x +3) - 6
Thus the expression becomes 2(x +3) - 6.
A loan is paid off in 30 years with a total of $99,000. It had a 3% interest rate that compounded monthly. What was the principal?
Answer:
The principle will be "40295.63". A further explanation is given below.
Step-by-step explanation:
The given values are:
Total amount,
A = 99,000
Rate of interest,
R = 3%
Time period,
T = 30 years
= 360 months
As we know,
⇒ [tex]A=P(1+\frac{{\frac{R}{12} }}{100} )^T[/tex]
On substituting the values, we get
⇒ [tex]99000=P(1+\frac{\frac{3}{12}}{100})^{360}[/tex]
⇒ [tex]99000=P(1+\frac{\frac{1}{4} }{100}) ^{360}[/tex]
⇒ [tex]P=\frac{99000}{(1.0025)^{360}}[/tex]
⇒ [tex]P=40295.63[/tex]
The required value of principal will be p = "40295.63".
Given,
Total amount of loan is = A = $99,000
Rate of interest = R = 3%
Time period =T = 30 years
Convert into months = 12×30
= 360 months
According to the question,
[tex]A = P ( 1+ \frac{\frac{R}{12} }{100} )^{360}[/tex]
Put the value of A = 99,000 , T = 360 , R= 3
[tex]99,000 = P [ 1+ \frac{\frac{3}{12} }{100} ]^{360} \\\\P = \frac{99,000}{(1.0025)^{360} }[/tex]
P = 40295.63
The required value of principal p = 40295.63 .

Here x and y are the real numbers.
A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
The sum of the x and y is (x + y)
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
One-half the sum of x and y = 1/2(x + y)

Ganesh is making a scale model of the Space Needle in Seattle, Washington. The space needle is 605 feet tall. If the model is 1/100 the actual size of the Space Needle, how tall is the model? _____ feet
Answer:
[tex]Model = 6.05ft[/tex]
Step-by-step explanation:
Given
[tex]Space\ Needle = 605ft[/tex]
[tex]Scale\ Model = \frac{1}{100}[/tex]
Required
Determine the height of the model.
To do this, we simply multiply the scale model by the height of the space needle.
[tex]Model = Scale\ Model * Space\ Needle[/tex]
[tex]Model = \frac{1}{100} * 605ft[/tex]
[tex]Model = \frac{605ft}{100}[/tex]
[tex]Model = 6.05ft[/tex]
Hence, the height of the model is 6.05ft
