I need help finding the answer too Y= 2.82x + 25.1

Answer:

x = -262/13, y = -5/13, z = 89/13

Step-by-step explanation:

Solve the following system:

{3 z + 4 y = 19 | (equation 1)

z - x = 27 | (equation 2)

-3 y + x = -19 | (equation 3)

Swap equation 1 with equation 2:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

x - 3 y + 0 z = -19 | (equation 3)

Add equation 1 to equation 3:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

0 x - 3 y + z = 8 | (equation 3)

Add 3/4 × (equation 2) to equation 3:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

0 x + 0 y + (13 z)/4 = 89/4 | (equation 3)

Multiply equation 3 by 4:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

0 x + 0 y + 13 z = 89 | (equation 3)

Divide equation 3 by 13:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Subtract 3 × (equation 3) from equation 2:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 0 z = -20/13 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Divide equation 2 by 4:

{-x + 0 y + z = 27 | (equation 1)

0 x + y + 0 z = -5/13 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Subtract equation 3 from equation 1:

{-x + 0 y + 0 z = 262/13 | (equation 1)

0 x + y + 0 z = -5/13 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Multiply equation 1 by -1:

{x + 0 y + 0 z = -262/13 | (equation 1)

0 x + y + 0 z = -5/13 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Collect results:

Answer: {x = -262/13, y = -5/13, z = 89/13

The time for the trough to have 80 gallons of water is 5 minutes.

A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

Let the number of minutes be represented as m.

The trough already contains 25 gallons of water, and the rancher is adding 11 gallons per minute. This will be:

25 + 11m =80

Collect like terms

11m = 80 - 25

11m = 55

Divide

m = 55 / 11

m = 5

Therefore, there will be 5 minutes.

Step-by-step explanation:

See attached worksheet.

Step-by-step explanation:

In x you can put the value which can given in question.

Here, x coordinate is 2 and y coordinate is -3, so we have to first move two units on right thereafter we will move three units downward.(for better understanding please see the attached graph).

A coordinate plane is formed by the intersection of a horizontal number line and a vertical number line. The number lines intersect at the origin and separate the coordinate plane into four regions called quadrants.

An ordered pair is used to locate a point in a coordinate plane.

ordered pair(P) = (2,-3).

The equation of the parallel line is y = x + 2.

What is Equation of line?

The equation of line with slope m and y intercept at point b is given as;

y = mx + b

Given that;

The point = C(4, 6)

And, equation of line is y = x + 7

Since, Slope of Parallel lines are always same.

So, The slope of the given line is calculated as;

y = x + 7

m = dy/dx = 1

Thus, Slope of parallel lines is 1.

Since, The equation of line is passes through point C (4, 6).

So, The equation of line with slope(m) 1 and point C(4, 6) is;

y - 6 = 1 (x - 4)

y - 6 = x - 4

y = x - 4 + 6

y = x + 2

Thus, The equation of the parallel line is y = x + 2.

Answer:

D: The mean will increase, and the median will stay the same.

Step-by-step explanation:

Strategy

The mean and median are two ways to describe the center of a data set.

When a data set is almost symmetrical, the mean and median are close together.

When a data set is not symmetrical, the mean is usually closer to the outliers or tail than the median.

Let's reason conceptually about the measures of the center since we do not know the exact values.

Reasoning about the median

There are 7 scores. When the scores are in order from least to greatest, the median is the 4th score.

The day when Anya scored 300 points was the largest score both before and after that score was increased. So that is the 7th score when we order them from least to greatest.

Changing the 7th score does not change the 4th score, so the median stays the same.

Reasoning about the mean

Let's remember how to calculate the mean:

mean = total points/number of rounds

The largest score increasing from 300 to 600 points increases the total number of points. However, it does not change the number of rounds. So the mean increases.

Conclusion

D: The mean will increase, and the median will stay the same.

To transform is to alter. So, changing any given geometric shape would be considered a geometric transformation.

What does one transformation mean?

A 180° rotation about the origin characterizes the sole transformation. Translation, rotation, reflection, and dilation are the four primary categories of transformation.

The term "Geometric" transformation refers to a group of picture transformations where the geometry of the image is modified without changing the actual pixel values. In general, various actions can be performed on it, but the actual pixel values will not change.

Students get the opportunity to consider fundamental mathematical concepts in novel ways thanks to geometric transformations (e.g., functions whose domain and range are R2). Students can view mathematics as a connected field by using geometric transformations as a framework.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent. Also, these angles are generally referred to as alternate interior angles.

Additionally, there are four (4) special angle relationships that are typically formed when two parallel lines are intersected by a transversal and these include the following:

The equivalent measures to 3 yards are;

108 inches and ; 6 ft 36 inches

Here, we want to get the values of the measurements that are equivalent to 3 yards

To do this, we need to know how to convert between the various measure types

We proceed as follows;

Mathematically, 1 yard is 36 inches; also, 1 yard is 3 feet

So, 3 yards is (3*36) = 108 inches

Also, 3 yards is (3*3) = 9 feet

Also, 1 ft is 12 inches;

So, 6 ft 12 inches is 7 feet

108 inches is as seen above, so 3 yards equal this

3 yards is not 108 feet as calculated above

6 ft 36 inches

36 inches is 3 ft; so by addition; 6 ft 36 inches is 9 ft

So, the correct answers here are 108 inches and 6 ft 36 inches

1 cubic foot is equivalent to 1728 cubic inches, this is why the statement is false.

1 square foot is equivalent to 144 square inches, so the second statement is also false.

If Jenny studies one hour both for economics and history she can gain 10+15=25 points

Increasing: Growing larger or greater. Therefore, if the derivative of a function is positive, then the function is increasing. Let's consider our example of g(x) = x2. The derivative of g(x) = x2 is g'(x) = 2x. Since we are multiplying x by the positive number 2, it's easy to see that g ' is positive when x is positive and negative when x is negative.

Jenny will receive 15 points if she simply studies economics, which equates to 10 points in the first hour and 5 points in the second.

Jenny will earn 20 points if she exclusively studies history, which equates to 15 points in the first class and 5 points in the second.

Jenny should study economics for one hour, which will get her 10 points, and history for one hour, which will gain her 15 points, for a total of 25 points in the two hours

So we concluded that if Jenny studies one hour both for economics and history she can gain 10+15=25 points

let a = 5 , b = 12 , c = 13 , then

Answer:

3, 4, 5

Step-by-step explanation:

In a right triangle, we have 2 legs and a hypotenuse. The hypotenuse equals c, while the other 2 legs are a and b.

Lets say a = 3, b = 4, and c = 5

The formula is a² + b² = c²

3² + 4² = 5²

9 + 16 = 25

25 = 25

Therefore, 3, 4, and 5 can be dimensions of a right triangle.

The greatest of the 4 consecutive integers with a sum of -278 is -68

Let n, n + 1, n + 2 and n + 3 be four consecutive integers.

The sum of four consecutive integers is -278.

⇒ n + (n + 1) + (n + 2) + (n + 3) = -278

⇒ n + n + n + n + 1 + 2 + 3 = -278

⇒ 4n + 6 = -278

⇒ 4n = -278 - 6

⇒ 4n = -284

⇒ n = -284/4

⇒ n = -71

So, the consecutive integers would would be:

n = -71

n + 1 = -70

n + 2 = -69

n + 3 = -68

here, the greatest of the 4 integers is -68

Therefore, the greatest of the 4 consecutive integers with a sum of -278 is -68
