Answer:

X = 9

Step-by-step explanation:

Write Equation: 20(x+1) = 200

Distribute 20: 20x +20 =200

Subtract 20: 20x = 180

Divide by 20x to leave x by itself: X=9

Brainliest?

Answer:

9

Step-by-step explanation:

First, we want to figure out what x + 1 is and we can do that by dividing both sides by 20 to get rid of the twenty on the left hand side:

(20(x+1)/20 = 200/20

Now we know that:

x+1 = 10

We subtract 1 from both sides and we now know that:

x+1 - 1 = 10 - 1

Which is:

x = 9

Step-by-step explanation:

Segments are named by their endpoints. Therefore, segment PQ will have endpoints P and Q. The length of the segment is equal to the distance between these points.

To find the distance between P and Q given their coordinates, use the distance formula:

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Let:

\(P(-2, 7)\implies (x_1, y_1),\\Q(1, 3)\implies (x_2, y_2)\)

The distance between these points is equal to:

\(d=\sqrt{(1-(-2))^2+(3-7)^2},\\d=\sqrt{3^2+(-4)^2},\\d=\sqrt{9+16},\\d=\sqrt{25},\\d=\boxed{5}\)

Answer:

\(5\)

Step-by-step explanation:

This problem gives one the following points on a line: (\(P(-2,7)\)), and (\(Q(1,3)\)). The problem asks one to find the distance between the two points. The formula to find the distance between two points on a coordinate point is the following,

\(D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Substitute the given values in and solve for the distance;

\(D=\sqrt{(-2)-(1))^2+((7)-(3))^2}\)

Simplify,

\(D=\sqrt{(-2)-(1))^2+((7)-(3))^2}\\\\D=\sqrt{(-3)^2+(4)^2}\\\\D=\sqrt{9+16}\\\\D=\sqrt{25}\\\\D = 5\)

True. With similar triangles, the corresponding angles are equal. This property is one of the fundamental characteristics of similar triangles.

Similar triangles are triangles that have the same shape but possibly different sizes. They have corresponding angles that are equal, meaning that the angles in one triangle match the angles in the other triangle. This correspondence allows us to establish proportional relationships between the corresponding sides of the triangles.

The corresponding angles of similar triangles are equal because the angles are determined by the shape and orientation of the triangles, rather than their size. If two triangles have the same shape, their corresponding angles will be equal regardless of their size or position.

This property is the basis for many geometric proofs and calculations involving similar triangles. It allows us to solve problems involving proportions, ratios, and scaling.

By knowing that the corresponding angles of similar triangles are equal, we can confidently apply the principles of similarity to find missing side lengths, determine unknown angles, or establish relationships between different parts of the triangles.

The value for a in quadratic function a(x-1)²+3 is obtained as a = 2.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The vertex of the quadratic function is (1,3).

The line passes through the points (3,5).

The equation is in the form - a(x-1)²+3

It is known that the vertex form of a quadratic function is f(x) = a(x-h)² + k, where (h,k) is the vertex of the parabola.

So it can be written -

f(x) = a(x-1)² + 3

Substitute the value of (1,3).

f(1) = a(1-1)² + 3 = 3

And for the point (3,5) the equation will be -

f(3) = a(3-1)² + 3 = 5

Set up a system of equations -

a(1-1)² + 3 = 3

a(3-1)² + 3 = 5

Solving for a in these equations -

a = 2

Therefore, the value of a is obtained as 2.

To solve for x at an angle, you must first understand what type of angle you are working with. If the angle is a right angle, you can use the Pythagorean theorem to solve for x. If the angle is an obtuse angle, you can use the law of cosines to solve for x. If the angle is an acute angle, you can use the law of sines to solve for x.

To solve for x at a right angle using the Pythagorean theorem, you must have the lengths of the two neighboring sides of the triangle. The sum of the squares of the two sides is equal to the square of the hypotenuse, according to the Pythagorean theorem. By rearranging the components and solving for x, this equation may be used to find x.

To use the law of cosines to solve for x at an obtuse angle, you must know the lengths of all three sides of the triangle. According to the law of cosines, the square of one side's length equals the sum of the squares of the other 2 sides minus twice the product of the other 2 sides multiplied by the cosine of the obtuse angle. You can use this equation to solve for x by rearranging the terms and solving for x.

To apply the law of sines to solve for x in an acute angle, you should first know the lengths of the triangle's two sides as well as the acute angle's measurement. According to the law of sines, the ratio of one side's length to the sine of the opposite angle equals the ratio of the other side's length to the sine of the acute angle. By rearranging the terms and solving for x, you may use this equation to solve for x.

The small boxes weigh 30 pounds, and the large boxes weigh 45 pounds.

Let the weight of the small box be x, and the weight of the large box be y. Then we have the following system of equations:x + y = 75 - Equation 1
We can see from the question that the truck is transporting 55 large boxes and 50 small boxes.
Therefore:55y + 50x = 3975 - Equation 2
We can use equation 1 to solve for x in terms of y, by subtracting y from both sides:x = 75 - y - Equation 3
We can substitute equation 3 into equation 2, to obtain:
55y + 50(75 - y) = 3975
This simplifies to:55y + 3750 - 50y = 3975
Simplifying further:5y + 3750 = 3975
Subtracting 3750 from both sides:5y = 225
Dividing both sides by 5:y = 45
Substituting y = 45 into equation 3, we can solve for x:x = 75 - 45x = 30

Therefore, the small boxes weigh 30 pounds, and the large boxes weigh 45 pounds.

The equation of the line which is perpendicular to MN is x -2y +5=0

The equation of a line with a slope of m and a y-intercept of (0, b) is

The IQR measures the spread of the middle 50% of the data.

Without knowing the actual values of the fuel economy ratings or the summary statistics, we cannot provide an exact answer. However, we can make some general observations about the effects of removing an extreme outlier on the standard deviation and the interquartile range (IQR).

First, the standard deviation measures the spread of the data around the mean. Removing an extreme outlier that is far from the mean could potentially decrease the standard deviation, as the remaining values may be more tightly clustered around the mean. However, the effect on the standard deviation will depend on the exact values of the data points and how much they vary from the mean.

Second, the IQR measures the spread of the middle 50% of the data. Removing an extreme outlier that is far from the bulk of the data may not have a significant effect on the IQR, as the remaining.

If x - 9 is a factor of x^2 - 5x - 36 equation, then the other factor is x + 4.

We can factor x - 9 out of x^2 - 5x - 36 as follows: \(x^{2}\) - 5x - 36 = (x-9)(x+4).

We know that x - 9 is a factor of x^2 - 5x - 36. Therefore, the remaining factor must be x + 4.

We can also verify this by substituting x = 9 into the equation x^2 - 5x - 36 = (x - 9)(x + 4). We get:

9^2 - 5(9) - 36 = 81 - 45 - 36 = 0

Since the left side of the equation is equal to 0, we know that x = 9 is a solution to the equation. Therefore, x - 9 must be a factor of the equation.
