The table that represents a proportional relationship between x and y is table 2.
What is a proportional relationship?A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor.
A proportional relationship is one in which two quantities vary directly with each other.
For example,
y = kx
where,
k = constant of proportionality
You can tell if a table shows a proportional relationship by calculating the ratio of each pair of values.
If those ratios are all the same, the table shows a proportional relationship.
Therefore, let's calculate the ratios of the table
1 / 155 / 75 = 1 / 158 / 120 = 1 / 1510 / 150 = 1 / 15Hence, the table 2 has a proportional relationship.

A carpenter has 2 pipes which are 60 dm and 72 dm long respectively. he cuts them into equal lengths. what is the greatest possible length of each pipe?
Using greatest common factor (GCF), the greatest possible length of each pipe is 12 dm.
The greatest common factor (GCF) of a set of numbers is defined as the largest common positive integer that divides each number into equal parts with zero remainder.
If a carpenter has 2 pipes which are 60 dm and 72 dm long, respectively and he cuts them into equal lengths, then the greatest possible length of each pipe is the GCF of 60 and 72.
60 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
72 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 24, 36, 72
common factors : 1, 2, 3, 4, 6, 12
GCF = 12

If you multiply two polynomials, will you always get a polynomial? Try combining some polynomials to answer your question. Use the ones given by your teacher or make up your own polynomials. Keep a record of what polynomials you tried, and the results. When you think you have an answer to your question, explain your reasoning using equations, graphs, visuals, calculations, words, or in any way that will help others understand your reasons.
Polynomials are closed under the multiplication operation, meaning that the result of the multiplication between two polynomials will always be a polynomial.
How to multiply polynomials?To multiply polynomials, we first apply the distributive property, multiplying all terms, then we combine the like terms, that is, adding all the terms that have the same exponents.
Since all the factors of the multiplications will be of polynomial terms, the results of the multiplication will be polynomial, and so will the like terms combined, hence polynomials are closed under the multiplication operation.
One example of multiplication of polynomials is given as follows:
(x² - 1)(x² + 1) = x²x² + x² - x² - 1 = x^4 - 1.

Just answer questions 12 and 13 !
Answer:
Step-by-step explanation:
12. We have : angle ABF = angle ABE + angle FBE = 2(w+11) + angle FBE = 8w - 6
-> angle ABE = 8w - 6 - [2(w+11)] = 8w - 6 - 2w - 22 = 6w - 28.
13. As we can see, angle EBA and angle EBC is a linear pair, therefore they're supplementary angles, adding up to 180.
-> 3r + 10 + 2r - 20 = 180
5r - 10 = 180
r = 38.
So, angle EBF = 2r - 20 = 76 - 20 = 56.

11. Write a function rule for the area of a rectangle with a length 7 m more than three
times its width. What is the area of the rectangle when its width is 3 m?
The area of the rectangle when its width is 3 m is 39m².
What is area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares. The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given Data
A function rule for the area of a rectangle with a length 7 m more than three times its width.
Area of rectangle = Length(Width)
Area of function = (w) (3w+7)
Area of function = 3w² + 7w
If w = 3m
Area of function = 3(3)² +7(3)
Area of function = 3(9) + 21
Area of function = 18 + 21
Area of function = 39
the area of the rectangle when its width is 3 m is 39m².

y = [ ? ]x + [ ]
i would appreciate the help!
The equation of the line passing through the points (2, 11) and (-8, -18) is y = 29 / 10 x + 26 / 5
How to find the equation of a line?The equation of a line can be express as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line passes through the points (2, 11) and (-8, -18).
Hence,
m = -18 - 11 / -8 - 2
m = - 29 / - 10
m = 29 / 10
Therefore, let's find the y-intercept using (2, 11)
The equation is as follows:
11 = 29 / 10(2) + b
11 = 58 / 10 + b
b = 11 - 58 / 10
b = 110 - 58 / 10
b = 52 / 10 = 26 / 5
Therefore,
y = 29 / 10 x + 26 / 5

Urgent | Find the angles of the following shape
Step-by-step explanation:
easy so first you are going to subtract 130 from 180 since any angle that is made on a straight line segment if subtracted you get the answer of the other angle
180-130 =50
I want you to draw this diagram on paper and extend the line S that is 50° since we know the angle SRQ =130
Now you will be able to see a Z formation PQR and the other half of the S is making a Z formation the interior angles of a z formation are always equal to each other
so the interior x =50°
extend the line P or Q out wards that will also be equal to the other side now since it also makes a Z formation
As we know that the angle SRQ is equal 130 we will half it or divide it by 2 the answer will be 65
one angle in R angle will be 65 while the other one will also be 65
Now we know two angles in the triangle PQR and one angle in triangle PRS
applay the formula that all interior angles sum =189
x + 65 + z =180 (name the left unknown angle z)
50 + 65 + z= 180
105+ z =180
z=180-105
z=75
we now all the angles in the triangle x
y angle =65 again apply the z formation to get the answer

1. Subtract the numbers
90 = 5p + 2 + 3p
2. Combine Like Terms
90 = 5p + 2 + 3p
90 = 8p + 2
3. Subtract 2 from both sides
90 - 2 = 8p + 2 - 2

two cards are drawn without replacement from a standard deck of 52 playing cards. what is the probability of choosing a diamond and then, without replacement, a black card? express your answer as a fraction or a decimal number rounded to four decimal places.
Answer:
13/102
Step-by-step explanation:
We start with 52 playing cards. Of these 52 cards, 13 are diamonds, So the probability of a diamond is 13/52, or 1/4. There are now 51 cards left. Since the diamond is a red card, there are 26 black cards. So the probability of a black card is 26/51. Multiplying 1/4 and 26/51, and then simplifying, we have 13/102.
