SOLUTION
The rational root theorem, also called rational root test theorem state that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, the leading coefficient (the coefficient of the highest power) must be divisible by the denominator of the fraction and the constant term (the one without a variable) must be divisible by the numerator.

Shelby is searching online for airline tickets. Two weeks ago, the cost to fly from to was $210. Now the cost is $305. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?
Answers
The percentage increase of the airline ticket is 45.24%
Percentage IncreaseThe concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increased by an additional 5 parts.
Mathematically, the percentage increase of a quantity can be written as
[tex]\% increase =\frac{change in quantity}{original quantity} * 100[/tex]
Let's substitute the values given into the equation and find the percentage increase.
[tex]\% increase =\frac{change in quantity}{original quantity} * 100\\\% increase = \frac{305 - 210}{210} *100\\\% increase = 45.24\%[/tex]
The increase in percentage of the ticket price is 45.24%
If the airline charges an additional $50 with the new ticket price, the percentage increase will remain the same because assuming the baggage fees is also applicable to the old price, there won't be an change in the percentage increase.

Answers
ANSWER
DE > EC > CD
EXPLANATION
Let us make a sketch of triangle CDE:
Let us first find the measure of angle E.
The sum of angles in a triangle is 180 degrees. This means that:
58 + 86 + 144 + =>
The sine of the angle of a triangle and side opposite that triangle is proportional for every angle and side of a triangle.
That is, the ratio of the sine of an angle and the side opposite that angle is constant for a triangle. This is known as the Sine Law.
This law implies that the bigger an angle of a triangle is, the larger the side opposite it and vice versa.
Therefore, since DE > EC > CD

What are Intersecting lines?They are referred to be intersecting lines when two or more lines in a plane cross each other. The point of intersection, which can be found on all intersecting lines, is the common point shared by the intersecting lines. The intersecting lines (two or more) always meet at a single location. Any angle can be used to intersect the intersecting lines. This angle is always larger than zero and less than 180 degrees. Vertical angles are created by two lines intersecting. With a common vertex, the vertical angles are opposite angles (which is the point of intersection). Curved lines, not straight ones, are what intersect at several points.To learn more about Intersecting Lines, refer to:

An airplane flying against the wind travels 280 miles in the same amount of time it would take the same plane to travel
420 miles with the wind. If the wind speed is a constant 70 miles per hour, how fast would the plane travel in still air?
Answers
The speed of plane in still air is 150 miles per hour.
What is speed?
Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
speed = distance/time
Let s = speed in still air
then(s-70) = ground speed against the wind
and
(s+70) = ground speed with the wind
Write a time equation; time = distance/speed
time against = time with still air
280/(s-30) = 420/(s+30)
Cross multiply
420(s-70) = 280(s+70)
420s - 29400 = 280s + 19600
420s-280s = 19600+29400
140s=49000
s = 49000/140
s = 350 mph

What is the length of AB? round your answer to the nearest hundred.
Answers
In order to calculate the length of the line AB, you use the following formula for the distance between points in the coordinate plane:
d = √((x2-x1)²-(y2-y1)²)
That is, it is only necessary to have a pair of points with coordinates (x1,y1) and (x2,y2). In this case you have two points A=(-5,-4)=(x1,y1) and B=(-3,3)=(x2,y2), then, by replacing these values into the formula for the distance you have:
d = √((3-(-3))²-(-5-4)²)
d = √((3+3)²+(-9)²)
d = √(36+81) = √(117) = 10.8166 ≈ 10.82
Hence, the length of the line AB is 10.82

7. An internet service provider charges $20 per month plus an initial set-up fee. One customer paid a total of $92 after 2 months of service. Write an equation in point-slope-form modeling this situation. Then, write the equation in slope-intercept form. What does the 52 represent in your slope-intercept form equation?
Answers
The internet service provider charges $20 per month plus an initial set-up fee.
Let "x" represent the number of months that are charged, then the monthly fee can be expressed as 20x
Let "y" represent the cost of the internet service after x months.
If the customer paid y=$92 after x=2 months of service, this information represents a point of the relationship that can be expressed as (2,92)
The point-slope form has the following formula:
[tex]y-y_1=m(x-x_1)[/tex]Where
m is the slope
(x₁,y₁) are the coordinates of one point of the line.
The slope of the line corresponds to the monthly fee for the internet service, so m=$20
The coordinates of the point you have to use is (2,92)
So the equation in point-slope form is
[tex]y-92=20(x-2)[/tex]To write the equation in slope-intercept form, the first step is to distribute the multiplication on the parentheses term:
[tex]\begin{gathered} y-92=20\cdot x-20\cdot2 \\ y-92=20x-40 \end{gathered}[/tex]Then pass "-92" to the right side of the equation by adding it to both sides of the equal sign:
[tex]\begin{gathered} y-92+92=20x-40+92 \\ y=20x+52 \end{gathered}[/tex]The equation in point-slope form is y-92=20(x-2)
The equation in slope-intercept form is y=20x+52
$20 is the slope of the equation and represents the monthly fee for internet service.
$52 is the y-intercept of the equation, it represents the initial set-up fee for the internet service.
