what does it mean to solve the system of equation?

Answers

Answer 1
Solving a system of equations usually means that you solve for a variable in a specific equation. Systems of equations consist of 2+ equations that contain the same variables.

Ex :

2x + 2y = 8
3x + 3y = 9

Then, using those equations, you solve for x & y

As shown, Suzi starts her hike at an elevation below sea level.whaen she reaches the end of the hike,she still below sea level at -127 feet. What was the change in elevation from the beginning of suzi's hike to the end

(Current elevation: -225 feet )

Answers

She was 98 feet higher after the hike. So the answer would be 98 feet

Current Position of Suzi below Level = -225 Feet

Now, Suzi Started her Hike

Position of Suzi after taking Hike from her initial Position= -127 feet

The change in elevation from the beginning of suzi's hike to the end

                  = -127 -(-225)

                  = -127 +225

                  = 98 feet

The change in elevation from the beginning of suzi's hike to the end=98 feet

Explain why each relationship is not proportional

Answers

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.

Hope this helps!

Final answer:

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.

Select the correct scientific notation form of this numeral using only 2 significant figures. 482.65

Answers

Final answer:

To write 482.65 in scientific notation with two significant figures, round the number to 480 and move the decimal point two places to the right, resulting in 4.8 x 10^2.

Explanation:

To write the given number 482.65 in scientific notation with two significant figures, we first determine the number of significant figures in the original number, which is five. Since we need to express it in two significant figures, we round the number to 480. Then, we move the decimal point to the right until we have a number between 1 and 10. In this case, we need to move it two places to the right, resulting in the scientific notation form of 4.8 x 10^2.

A horse ran 800 meters in 40 seconds, 1,200 meters in 60 seconds,and 480 meters in 24 seconds. Is this a proportional relationship? If so, what is the constant of proportionality? What does it represent. Write an equation to represent the distance d , in meters, that the horse runs in t seconds

Answers

Yes, there is a proportional relationship in this data, it’s is 20 meters per second. It represents the horse running at 20 meters per second. The constant of proportionality is 20/1 The equation would be 20t=d

The given data is in proportion. Therefore, an equation to represent the distance d ,in meters, that the horse runs in t seconds is d=20t.

What is a proportional relationship?

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Given that, a horse ran 800 meters in 40 seconds, 1,200 meters in 60 seconds and 480 meters in 24 seconds.

Here,

800/40 =20, 1200/60 =20 and 480/24=20

Now, in proportional relationship d∝t

d=kt

800=k×40

k=20

d=20t

The given data is in proportion. Therefore, an equation to represent the distance d ,in meters, that the horse runs in t seconds is d=20t.

2m-nx=x+4
Solve for x

Answers

The solution is x = (2m - 4) / (n + 1).

To solve the equation 2m - nx = x + 4 for x, we need to collect all the x terms on one side of the equation. Here are the steps to do that:

Start by subtracting x from both sides of the equation to get 2m - nx - x = 4.

Next, combine like terms by adding -nx and -x together to get 2m - (n+1)x = 4.

Now, solve for x by dividing both sides of the equation by -(n+1) to isolate x.

The solution is x = (2m - 4) / (n + 1).

This is how you solve for x when dealing with linear equations with variables on both sides. The key is to isolate the variable you are solving for by using inverse operations and keeping the equation balanced

What is 21 divided by 4552
Show ur work

Answers

Final answer:

To find what 21 is divided by 4552, you can use long division but it's easier to use a calculator, which gives an approximate result of 0.0046 when rounded to four decimal places.

Explanation:

The question asks us to perform the division of 21 by 4552. To solve this, we can use long division or a calculator. Using a calculator would be faster and more accurate for most, but here we will demonstrate the process using long division.

Here are the steps to perform this division by hand:

Place 21 inside the division bracket and 4552 outside, to the left.Since 21 is less than 4552, we cannot divide it directly, so we have to add decimal places to 21, effectively dividing by a larger power of ten each time.Add one decimal place to 21, making it 210 (since we can't divide 21 by 4552), and see how many times 4552 can go into 210. Since 4552 is still larger, add another decimal point, making it 2100, and so on.Once we reach a number where 4552 can divide into, we perform the division as with whole numbers and get our result.

For simplicity and accuracy, most would use a calculator, and it would show that 21 divided by 4552 equals approximately 0.0046 when rounded to four decimal places.

Remember to round the result according to the number of significant figures or decimal places required by your instructions.

Final answer:

To divide 21 by 4552, divide the first number by the second number.

Explanation:

To divide 21 by 4552, we divide the first number by the second number.

So, 21 ÷ 4552 = 0.0046 (rounded to four decimal places).
