the length of a cube is x centimeters. If x is an integer why can't the volume of the cube equal 15 cm cubed
The volume of a cube with a side length of x centimeters cannot equal 15 cm³ when x is an integer.
Explanation:The question asks why the volume of a cube with a length of x centimeters cannot equal 15 cm³ when x is an integer. In order to calculate the volume of a cube, we use the formula V = s³, where V represents the volume and s represents the length of a side. If x is an integer, the length of the cube can be any integer value.
However, when we substitute x = 15 into the formula, we find that the volume of the cube would be 15³ = 3375 cm³, which is not equal to 15 cm³. Therefore, the volume of a cube with a side length of x centimeters cannot equal 15 cm³ when x is an integer.

What is system of equations?In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought
Given is the system of equations -
5x - 2y = 11
3x + 5y = 19
Multiply Eq.{1} by 3 and Eq.{2} by 5, we get -
15x - 6y = 33
15x + 25y = 95
Now, performing Eq(2) - Eq(1), we get -
15x + 25y - 15x + 6y = 95 - 33
31y = 62
y = 2
x = 11 + 2y/5
x = 15/5
x = 3
Therefore, the solution set for the system of equations is (3, 2).

The variation in any sample group is simply the square of the correlation coefficient, that is:
variation = r^2
Therefore given an r value, we can simply directly calculate for variation percentage.
variation = (0.743)^2
variation = 0.552 or 55.2%
Answer:
B. 55.2%
The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Both Samuel and Helena are correct as the slope-intercept form and the point-slope form can be used to find the equation of a line given two points. The slope-intercept form is y = mx + b, while the point-slope form is y - y1 = m(x - x1). The methods vary but both are effective depending on the given information.
Explanation:Both Samuel and Helena are correct; they have mentioned different forms that can be used to find the equation of a line given two points. The slope-intercept form of a linear equation is commonly written as y = mx + b, where m represents the slope and b represents the y-intercept. The slope, m, describes the steepness of the line, and the y-intercept, b, is where the line crosses the y-axis. In contrast, the point-slope form is written as y - y1 = m(x - x1), where (x1, y1) is a specific point on the line and m is the slope. To find the slope, you take two points on the line, say, (x1, y1) and (x2, y2), and use the formula m = (y2 - y1)/(x2 - x1).
Either form will produce the equation of the line, but they require different approaches. The slope-intercept form immediately gives the y-intercept and is generally used when this information is valuable or when the graph will be drawn. Meanwhile, the point-slope form is particularly handy when you have one point on the line and the slope, as it can be used quickly without re-arranging the equation to solve for the y-intercept.

Both Samuel and Helena's methods are valid for finding the equation of a line. The slope-intercept form (y = mx + b) requires finding the y-intercept, while the point-slope form (y - y1) = m(x - x1) uses a point on the line directly. Both forms yield the same final equation.
Both Samuel and Helena are correct, but they are using different methods to find the equation of a line. The slope-intercept form and the point-slope form can both lead to the same final equation of the line, which will be consistent after simplifying. Here's a step-by-step explanation of both forms:
Slope-Intercept Form (y = mx + b)Slope-Intercept Form is given by the equation y = mx + b, where m is the slope of the line and b is the y-intercept.
First, find the slope (m) using the formula: m = (y2 - y1) / (x2 - x1).Next, use one of the given points (x1, y1) and substitute in the found slope and coordinates to solve for b (the y-intercept).Substitute the slope and y-intercept back into the slope-intercept form.Example:
Given points (1, 2) and (3, 4):
Calculate the slope: m = (4 - 2) / (3 - 1) = 2 / 2 = 1.Use one of the points to find b: 2 = 1(1) + b; solving this, we get b = 1.Equation of the line: y = 1x + 1.Point-Slope Form (y - y1) = m(x - x1)The Point-Slope Form is given by the equation y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
First, find the slope (m) using the same formula: m = (y2 - y1) / (x2 - x1).Use one of the given points (x1, y1) and substitute in the found slope.Simplify the equation to convert it to slope-intercept form if needed.Example:
Given points (1, 2) and (3, 4):
Calculate the slope: m = (4 - 2) / (3 - 1) = 2 / 2 = 1.Select point (1, 2): y - 2 = 1(x - 1).Simplify: y - 2 = x - 1;y = x + 1.
Both forms ultimately lead to the same linear equation. Choosing which form to use depends on what information is given and personal preference.

The length of a rectangle is 5cm more than its width. The perimeter of the rectangle is 46cm. Find the width and the length
The width of the rectangle is 9 cm, and the length is 14 cm.
Explanation:To find the width and length of the rectangle:
Let's assume that the width of the rectangle is x cm. According to the problem, the length of the rectangle is 5 cm more than its width, so the length would be x + 5 cm.
The perimeter of the rectangle is 46 cm. The formula for the perimeter of a rectangle is P = 2(w + l), where P is the perimeter, w is the width, and l is the length.
So, we can set up the equation: 46 = 2(x + (x + 5)).
Simplifying the equation gives us: 46 = 2(2x + 5).
Expanding the equation further gives us: 46 = 4x + 10.
Subtracting 10 from both sides of the equation gives us: 36 = 4x.
Dividing both sides of the equation by 4 gives us: x = 9.
Therefore, the width of the rectangle is 9 cm, and the length is 9 + 5 = 14 cm.
To find the width and length of the rectangle, set up an equation using the given information and solve for x. The width is 9 cm and the length is 14 cm.
Explanation:To solve this problem, we can set up an equation using the information given. Let's assume the width of the rectangle is x cm. Since the length is 5cm more than the width, it will be x + 5 cm. The perimeter of a rectangle is found by adding all its sides, so we have:
2(x + x + 5) = 46
Simplifying this equation gives us:
4x + 10 = 46
Subtracting 10 from both sides:
4x = 36
Dividing both sides by 4:
x = 9
Therefore, the width of the rectangle is 9 cm and the length is 9 + 5 = 14 cm.
