The solution is, the last possibility is 9x^2 y – 5xy3 + 9x2y =18x^2 y – 5xy3, binomial degree 4.
What are Polynomials?Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.
here, we have,
First, if we have a polynomial that the form is as follow
P(x,y)=a1x^n-1y^p-1+ a2x^n-2y^p-2 + . . . . + a0xy+c,
the degree can be found with the sum of the highest value of power of each term.
If the number of term is 3, it is called trinomial, if it is 2, the polynomial is called binomial.
So in our case, 0– 5xy3 + 9x2y is a binomial with a degree of 4, because number of term 2, degree =1 + 2 =3, upper than 2+ 1(the second term) 4xy^3– 5xy3 + 9x2y = -xy3 +9x2y, binomial degree 4,
and the last possibility is 9x^2 y – 5xy3 + 9x2y =18x^2 y – 5xy3, binomial degree 4.
Hence, The solution is, the last possibility is 9x^2 y – 5xy3 + 9x2y =18x^2 y – 5xy3, binomial degree 4.

Step-by-step explanation:
Two angles are supplementary. The measure of the smaller angle is four more than one third the measure of the larger angle. The measure of the larger angle is
Answer:
132
Step-by-step explanation:
2 Angles are supplementary:
x + y = 180
The smaller angle is four more than one third of other:
y = 1/3x + 4
Plug in y into the original equation:
x + 1/3x + 4 = 180
Solve the equation:
4/3x = 176
x = 176 * 3/4
x = 132
y = 48
x is the larger angle so 132 is the answer
The measure of smaller and larger angles will be 48 degrees and 132 degrees, respectively.
Given information:
The two angles are supplementary. Let them be x (larger) and y (smaller).
The measure of the smaller angle is four more than one-third the measure of the larger angle.
The above condition can be written as,
[tex]y=4+\dfrac{ x}{3}[/tex]
Supplementary angles are the angles whose sum of measure is equal to 180 degrees.
So, [tex]x+y=180[/tex]
Solve the above two equations as,
[tex]x+y=180\\x+(4+\dfrac{ x}{3})=180\\\dfrac{4x}{3}=176\\x=176\times \dfrac{3}{4}\\x=132\\y=48[/tex]
Therefore, the measure of smaller and larger angles will be 48 degrees and 132 degrees, respectively.

What is the value of g?
−5+7g=3g+9
g=−1
g = 1
g=125
g=312
Answer:
D
Step-by-step explanation:
We have the equation:
[tex]-5+7g=3g+9[/tex]
Add 5 to both sides:
[tex]7g=3g+14[/tex]
Subtract 3g from both sides:
[tex]4g=14[/tex]
Divide both sides by 4:
[tex]g=14/4[/tex]
We can spilt this into:
[tex]g=12/4+2/4[/tex]
Simplify:
[tex]g=3\frac{1}{2}[/tex]
So, our answer is D.
And we're done!
Answer:
g = 3 1/2
Step-by-step explanation:
−5 + 7g = 3g + 9
Subtract 3g from both sides.
−5 + 4g = 9
Add 5 to both sides.
4g = 14
Divide both sides by 4.
g = 14/4
Reduce the fraction.
g = 7/2
Change the fraction into a mixed numeral.
g = 3 1/2

A biker travels the 120 mi from New York , NY to Wilmington, DE in 8 hours. A bus, a truck, and a rider on a horse take the same route as the biker. At what speed does each of them travel if it takes them 2 hours, 2.5 hours, and 18.75 hours respectively to reach Wilmington? Do the speed and the time vary directly or inversely proportional when the same distance is traveled? Explain why.
Answer:
The speed is inversely proportional to the time when the same distance is traveled.
Step-by-step explanation:
Given that:
The distance traveled by the biker in 8 hours is 120 mi.
The speed of the biker=120/8=15 mi/hr.
[as speed=Distance travelled/Time taken]
As all take the same route, so the distance traveled by all is the same which is 120 mi
The time taken by the bus to cover this distance is 2 hours.
So, the speed of the bus = 120/2=60 mi/hr.
The time taken by the truck is 2.5 hours.
So, the speed of the truck = 120/2.5=48 mi/hr.
And the time taken by the rider is 18.75 hours.
So, the speed of the rider = 120/18.75=6.40 mi/hr.
Now, observe that to cover the same distance, the bus takes the least time, so, the bus is traveling at the fastest speed among all, while the rider has the slowest speed as the distance is the same for all. The truck and the biker have speed in between the speed of the bus and the rider.
It can be concluded that when the time of the journey for the same distance is less than speed is more.
So, the speed is inversely proportional to the time when the same distance is traveled.
Or, [tex]\text{Speed}\propto\frac{1}{Time}[/tex]

A map on a coordinate plane places two cities on coordinates. Upland is located at (25, 5) and Highland is located at (50, 10). If each unit on the map represents one mile, approximately how many miles apart are the two cities?
Answer:
Approximately 25.5 miles
Step-by-step explanation:
Location of both the cities are [tex] (25,\: 5)=(x_1, \:y_1) \:\&\: (50,\: 10)=(x_2 , \:y_2) [/tex]
The distance between two cities can be obtained by using distance formula:

Which line is perpendicular to a line that has a slope of -1/3?
a. line MN
b. line AB
c. line EF
d. line JK
Answer:
Option (c)
Step-by-step explanation:
Slope of a line that passing through two points M(-1, 4) and N(2, -5),
[tex]m_1[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{-1-2}{4+5}[/tex]
= -([tex]\frac{3}{9}[/tex])
= -[tex]\frac{1}{3}[/tex]
To find the line perpendicular line to MN we will use the property,
[tex]m_1\times m_2=-1[/tex]
Where [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of two perpendicular lines.
Slope of line perpendicular to MN [tex](m_2)[/tex] will be,
[tex]-\frac{1}{3}\times m_2=-1[/tex]
[tex]m_2=3[/tex]
Slope of line joining two points J(-3, -4) and K(3, -2),
Slope = [tex]\frac{-4+2}{-3-3}=\frac{1}{3}[/tex]
Slope of line joining two points A(-3, 2) and B(3, 0)
Slope = [tex]\frac{2-0}{-3-3}=-\frac{1}{3}[/tex]
Slope of the line joining points E(0, -3) and F(2, 3),
Slope = [tex]\frac{-3-3}{0-2}[/tex] = 3
Therefore, line EF is perpendicular to the line MN.
Option (c) is the answer.

A class of 24 students went on a picnic. They had a choice between having a turkey sandwich or a vegetarian sandwich. Eighteen students selected turkey, and the rest selected vegetarian. Write a ratio to compare the number of turkey sandwiches to the number of vegetarian sandwiches.
4 : 3
4 : 1
1 : 3
3 : 1
I believe it is the ratio 3 : 1.
18 students chose the turkey sandwich.
Since the class has a total of 24 students, we can deduce that 6 students chose the vegetarian sandwich.
This gives us a ratio of 18 : 6.
When simplified, we get a ratio of 3 : 1.

What can teachers do to alleviate statistics anxiety in their students? To explore this question, statistics anxiety for students in two classes was compared. In one class, the instructor lectured in a formal manner, including dressing formally. In the other, the instructor was less formal, dressed informally, was more personal, used humor, and called on students by their first names. Anxiety was measured using a questionnaire. Higher scores indicate a greater level of anxiety. The mean anxiety score for students in the formal lecture class was 25.40 . In the informal class, the mean was 20.41 . Classify 25.40 and 20.41 as parameters or statistics.
Answer: Statistic
Step-by-step explanation: The difference between a parameter and statistic lies in the set of observation from which either quantity is derived. The parameter represents numerical values which are derived by examining or considering an entire population while the statistic is used to define numerical quantities derived from subset of the population called the sample. In the scenario described above, the population of interest would be the entire population of student and hence statistical derivations made would be called parameters. However, the scenario only experimented using student from two different classes which is a subset of the entire population of student. Hence, the obtained mean values of 25.40 and 20.41 for students in the formal and informal classes are categorized as statistic.
