X needs to be multiplied by the same number each time to get Y. Each time you have to multiply X to get Y, the number you have to multiply by is different. If the relationship was proportional, you could take one number and multiply it by X to get Y.
Ex.
X= 2, 6, 8, 12, 18
Y= 1, 3, 4, 6, 9
The rule there is that you have to multiply X by 2 to get Y.

A relationship is not proportional when the variables involved do not exhibit a constant rate of change or when the pattern on a graph deviates from a straight line.
Explanation:When a relationship is not proportional, it means that the variables involved do not change at a constant rate. There can be various reasons why a relationship is not proportional:
Scatter or uncertainty: In some cases, the data points representing the relationship scatter widely on a graph, indicating a lack of a straight line relationship. This can happen when there are external factors influencing the relationship.Non-linear patterns: Certain relationships, such as the period-luminosity relation for variable stars, do not follow a straight line on a graph. The points representing the stars may not fall along a single line, indicating a non-linear relationship.Unequal fractions: When analyzing relationships, fractions of the total force or variation may not be equal. This indicates that the relationship is not proportional. While it is possible for the fractions to be equal, it is more common for them to be unequal.Overall, a relationship is not proportional when the variables involved do not exhibit a constant rate of change or when the pattern on a graph deviates from a straight line.

12.75 is 25% of what number
Answers
The number that would have 12. 75 being 25 percent of it would be 51.
How to find the number ?To find the number of which 12. 75 is 25 %, you can set up a proportion and solve for the unknown number ( let's call it " x ").
You can write the proportion as:
( 25 / 100 ) * x = 12. 75
Now, simplify the left side of the equation:
( 1 / 4 ) * x = 12.75
To solve for x, multiply both sides by 4 to isolate x:
x = 12. 75 * 4
x = 51
So, 12. 75 is 25% of the number 51.

3-74. Mentally calculate the following products. Use the rule for decimal multiplication to write an equation in which the decimal point is written in the correct location. Homework Help ✎ (−0.04)(−0.1) (0.03)(−0.02) (0.7)(0.4) Stacey said, “Stephanie, look at my answer to the last problem, 0.7 · 0.4 = 0.28. Usually when I multiply, I get a bigger answer than the numbers I start with. Twenty-eight hundredths, 0.28, is less than either 0.4 or 0.7. I must have made a mistake.” Stephanie responded, “Well, one half times one half is one fourth, and one fourth is less then one half. I think when you multiply by a fraction or decimal less than one, you get less than you started with.” Write a sentence or two about who you think is correct and why.
Answers
Final answer:
Stephanie is right; when you multiply decimals less than one, the result is smaller than the original numbers. The multiplication of (-0.04)(-0.1) is 0.004, (0.03)(-0.02) is -0.0006, and (0.7)(0.4) is 0.28. These examples illustrate the rule correctly.
Explanation:
Stephanie is correct in her explanation to Stacey. When multiplying two numbers where one or both numbers are less than one, the product will be smaller than the original numbers. This is because you are essentially taking a fraction of each number. Let's confirm this by calculating the products of the given examples.
Multiplication of Negative Decimals: The product of negative decimals will be positive (since a negative times a negative equals a positive). For (-0.04)(-0.1), the product is 0.004.Multiplication of Mixed Decimals: The product of a positive and a negative decimal will be negative. For (0.03)(-0.02), the product is -0.0006.Multiplication of Positive Decimals: As in Stacey's example, (0.7)(0.4) equals 0.28, which is indeed less than either 0.4 or 0.7 because you're multiplying fractions of a whole number.Moreover, in scientific notation, moving the decimal and using placeholders is crucial for accurate answers. Multiplying 2.4 by 100 moves the decimal two places to the right, giving us 240.

Applying the rules that makes a relation a function:
1. The relation that doesn't represent y as a function of x is: D. Answer J.
2. The only set of ordered pairs showing a relation that represents y as a function of x is: A) {(-9, 2), (0, 6), (1, -2), (-3, 6)}.
Recall:
A relation is a function if every input value (x-value) has only one possible y-value that is related to or corresponds to.Let's analyze each relation given:
1. All the relations in F, H, and G all have only one y-value assigned or related to every x-value (input). Hence, they all represent y as a function of x.
The graph in J does not represent y as a function of x because of the following:
x =-3 has two y-values, -2, and -3x = -2 has two y-values, 0, and -1.x = -1 has two y-values, 1, and 2.x = 0 has two y-values, 3, and 4.Therefore, answer J does not represent a function.
2. Same rule of a function applies here.
From the set of ordered pairs given, only the set of ordered pairs in A represents y as a function of x because it every of its x-values has only one possible y-value assigned to them.The rest set of ordered pairs have more than one y-values assigned to some of their x-values.In summary:
1. The relation that doesn't represent y as a function of x is: D. Answer J.
2. The only set of ordered pairs showing a relation that represents y as a function of x is: A) {(-9, 2), (0, 6), (1, -2), (-3, 6)}.

An architect is designing a house in which a 104 square foot room and a 130 square foot room share a wall what is the greatest possible integer length of the shared wall -- THIS QUESTION WAS ASKED AND ANSWERED. BUT ANSWERED INCORRECTLY. NOTE THE ANSWER GIVEN CHANGED THE DIMENSIONS TO 140 FROM 104. AND THIS WEBSITE WILL NOT ALLOW ME TO REPORT THAT.
Answers
Then, the area of both squares have x as common factor.
So, x is the greatest common factor of 104 and 130.
You should know how to calculate the greatest common factor of two integers.
Just find the prime factors and choose the common factors raised to the lowest exponent.
104 = (2^3) (13)
130 = (2) (5)(13)
=> the greatest common factor is 2 * 13 = 26, and that is the greatest possible integer length of the shared wall.
Answer: 26

add 3 to both sides.

divide by 4 on both sides
your answer would be d=4
For ALL of the equations, you want to solve for the variable (letter) and get it by itself. So,
#1- The equation is 3n + 5 = 6. We want to subtract 5 from the left side, so 3n can be by itself. BUT, if we subtract 5 from the left, we also need to do it to right side. The equation is now: 3n = 1. We then want "n" by itself, so we need to divide "n" by 3 to get "n" by itself. Again, if we do it to the left side, we need to do it to the right. After you simplify, the equation simplifies to: n = 1/3 (in decimal form, the decimal would be repeating {0.33333}).
#2- The equation is 4 + 5x = 1. To get "5x" by itself on that side, let's subtract 4 to that side and the right side. After you do that, it'll be: 5x = -3. Then divide "x" by 5 to each side. The answer is: x= -3/5 (-0.6).
#3- The equation is 4y - 15 = -10. If we want "4y" by itself, we will do the opposite of subtracting 15 to adding 15 to both sides. After you do that, it'll be: 4y = 5. To finish it off, divide "y" by 4 to both sides. That will get you with:
y = 5/4 (1.25).
#4- The equation is 3 - 4d = 13. To get 4d by itself, let's subtract 3 to each side. That'll leave you with: -4d = 10. Now divide d by "-4" to both sides. The answer is: d = -10/4 (-2.5).
#5- The equation is 8 = 9x - 7. Let's add 7 to each side so that 9x can be by itself. After we do that, it's simplified to: 15 = 9x. Finish it off by dividing "x" by 9 to both sides. That'll leave you with the answer: x = 15/9 (in decimal form, this decimal would be repeating {1.66666}).
