The required value of x is 49.

A mathematical expression is a phrase that contains a minimum of two numbers or variables and at least one mathematical procedure. It is possible to multiply, divide, add, or subtract in arithmetic.

Simplifying the left side of the equation, we get:

x - (-1) = x + 1

So the equation becomes:

x + 1 = 50

Subtracting 1 from both sides, we get:

x = 49

Therefore, the value of x is 49.

The equation of the line is (y - 1/12) = -4/3(x - 7/5).

What is the slope of a line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinates to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are represented by y and x, respectively.

Consequently, the formula for the change in the y-coordinate with respect to the change in the x-coordinate is

m = y/x = y/x = change in y/change in x

where "m" represents a line's slope.

Additionally, the slope of the line can be depicted by

tan θ = Δy/Δx

So, the slope of a line is tan.

The given equation of a line is:

3x-4y=7

-4y = -3x + 7

y = 3/4 x - 7/4

The slope of the line is 3/4.

The slope of the line perpendicular to the given line is - 1/m = - 4/3

The point-slope of a line is y - y₁ = m(x - x₁).

The given point is (7/5,1/12)

The length of one side of the equilateral triangle in terms of x is 6x.

To find the length of one side of the equilateral triangle in terms of x, we need to consider the perimeter of both the rectangle and the equilateral triangle.

The perimeter of a rectangle is given by the formula:

Perimeter of rectangle = 2(length + width)

In this case, the length of the rectangle is 7x cm, and the width is 2x cm. Substituting these values into the formula, we have:

Perimeter of rectangle = 2(7x + 2x) = 2(9x) = 18x

We are told that the equilateral triangle has the same perimeter as the rectangle.

Since an equilateral triangle has all sides equal, the perimeter can be calculated by multiplying the length of one side by 3.

Therefore, we have:

Perimeter of equilateral triangle = 3(side length)

Since the perimeter of the equilateral triangle is equal to the perimeter of the rectangle (18x), we can set up the equation:

3(side length) = 18x

Dividing both sides of the equation by 3, we get:

side length = 6x

Hence, the length of one side of the equilateral triangle in terms of x is 6x.

-19.99; The line of best fit underpredicts the student's science test score.

So correct option is A.

A prediction is an estimation or forecast about future events or conditions, based on past data and trends, current information, and/or mathematical models. Predictions can be made in various fields, such as finance, weather, sports, social sciences, and natural sciences. The accuracy of predictions depends on many factors, including the quality of the data used, the assumptions made, the complexity of the system being analyzed, and the reliability of the methods used. Predictions are not always accurate and are often subject to revision as new information becomes available.

The predicted science score for the student with IQ 100 can be calculated using the line of best fit:

ŷ = −20.3 + 0.7489 * 100 = 71.59

The residual is the difference between the actual science test score and the predicted science score:

residual = actual score - predicted score = 52.6 - 71.59 = -19.99

So the line of best fit underpredicts the student's science test score by 19.99 points.

All points that satisfy this Inequality will lie in the solution set.

Given that Start Fraction (x minus 2) squared Over 25 End Fraction + Start Fraction (y + 3) squared Over 4 End Fraction less-than 1, we need to find out which point lies in the solution set.

So, let's analyze the given inequality. We haveStartFraction (x minus 2) squared Over 25 EndFraction + StartFraction (y + 3) squared Over 4 EndFraction less-than 1Since the first term is a fraction with the denominator of 25, it will be maximum when the numerator is minimum. Similarly, the second term will be maximum when the numerator is minimum. Therefore, the given inequality will be maximum when x = 2 and y = -3.

Now, we can substitute these values into the inequality to find out the maximum value of the left side of the inequality. We haveStart Fraction (2 minus 2) squared Over 25 EndFraction + StartFraction (-3 + 3) squared Over 4 EndFraction = 0 + 0 = 0Since this value is less than 1,

all points that are close enough to (2, -3) will be a part of the solution set. In other words, all points whose distance from (2, -3) is less than the distance from (2, -3) to the point on the ellipse that is farthest from it, will be a part of the solution set.

Now, we need to find out the farthest point from (2, -3) on the ellipse.

We know that the ellipse has semi-major and semi-minor axes of lengths 5 and 2 respectively. Therefore, the farthest point from (2, -3) will be the point on the ellipse that lies on the major axis and is farthest from (2, -3).

This point will be (2, -3 + 2) = (2, -1). Therefore, the distance between (2, -3) and (2, -1) will be the maximum distance between (2, -3) and any point on the ellipse. We have d = |-3 - (-1)| = 2.

Therefore, the solution set will contain all points whose distance from (2, -3) is less than 2. In other words, the solution set will be a circle with center at (2, -3) and radius of 2.

We can write the equation of this circle as (x - 2)² + (y + 3)² < 4.

Therefore, all points that satisfy this inequality will lie in the solution set.

For example, the point (2, -2) satisfies this inequality, and therefore lies in the solution set.

To determine which point lies in the solution set of the given inequality, we need to compare the value of the left side of the inequality to 1. Let's start by rearranging the inequality:

(x - 2)^2/25 + (y + 3)^2/4 < 1

If the left side of the inequality is less than 1, then the point (x, y) lies in the solution set. If the left side equals 1 or is greater than 1, then the point is not in the solution set. To visually represent the solution set, we can graph the equation of an ellipse.

The given sequence is defined as aₙ = 1 / (7n + 3).

To determine if the sequence converges or diverges, we need to analyze its behavior as n approaches infinity.

As n increases, the denominator 7n + 3 also increases which means that the values of aₙ will get smaller and smaller, approaching zero as n becomes larger.

The probability of a z-score at 0.41 is 0.1591. The mean length of the sample of 39 boards greater than 90 inches is 0.0037.

Mean = μ = 90 inches

Standard deviation = σ = 0.7 inch

(a) To calculate the probability of a machine that has a length greater than 90.29 inches by using the z formula

z = (x - μ) / σ

z = (90.29 - 90) / 0.7

z = 0.41

By using the standard normal distribution table, the probability of a z-score at 0.41 is 0.1591.

(b)

Mean length = 39 boards

Standard deviation = \(0.7 / \sqrt{39}\) = 0.112

We need to use the limit theorem to calculate the sampling distribution.

z = (x - μ) / (σ /\(\sqrt{n}\))

z = (90.29 - 90) / (0.112)

z = 2.68

By using the standard normal distribution table, the probability of a z-score at 2.68 is 0.0037.

The equation of the line that passes through the point (-6, -8) and is parallel to the line x - 2y = 6 is y = (1/2)x - 5

An equation of a line can be written in the form y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

To find the equation of a line that passes through a specific point and is parallel to another line, we can use the slope of the other line and the coordinates of the specific point.

The given line has the equation x - 2y = 6. To put this equation in slope-intercept form, we can add 2y to both sides, giving us x = 2y + 6. Rearranging the terms gives us y = (1/2)x + 3. This is the equation of the given line in slope-intercept form, with slope m = 1/2 and y-intercept (0, 3).

Since the line we are trying to find is parallel to the given line, it will have the same slope of 1/2. We can use this slope and the coordinates of the specific point (-6, -8) to write the equation of the line in slope-intercept form:

y = (1/2)x + b

-8 = (1/2)(-6) + b

-8 = -3 + b

b = -8 + 3

b = -5

Substituting this value of b into the equation gives us the final equation:

y = (1/2)x - 5

Thus, y = (1/2)x - 5 is the equation of the line that passes through the point (-6, -8) and is parallel to the line x - 2y = 6.
