A line with an undefined slope is a vertical line parallel to the y- axis with equation

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (4, - 3 ) with x- coordinate 4 , then

x = 4 ← equation of line

We can conclude after answering the presented question that Hence the equation slower train's speed is 13.25 miles per hour, while the faster train's speed is 27.25 miles per hour (13.25 + 14).

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the number "9". The purpose of equation solving is to determine the value or readings of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. In the calculation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

Because we know the two trains are going in the same direction, their relative speed equals the total of their speeds, which is (x + x+14) = 2x + 14.

We also know that the distance between them is shrinking at a pace of 648 miles in 4 hours, or at a rate of 648/4 = 162 miles per hour.

[tex]162 = (2x + 14) x 4 = distance = rate x time\\162 = 8x + 56\\106 = 8x\sx = 13.25\\[/tex]

Hence the slower train's speed is 13.25 miles per hour, while the faster train's speed is 27.25 miles per hour (13.25 + 14).

In the given right angle, the required value of x is 10° respectively.

Right-angled shapes can be any polygon, ranging from triangles to figures with numerous sides.

Right-angled shapes like squares and rectangles have exactly 4 right angles that add up to 360 degrees.

Right angles can also be found in other shapes like trapezoids, pentagons, and hexagons.

An angle with a measure of exactly 90 degrees (or /2) is referred to as a right angle.

The proper angles are frequently demonstrated in everyday life. For instance, the edges of the cardboard or the corner of a book.

So, we know that the given angles together make a right angle as:

2x + 8 + 62 = 90

Then, solve for x as follows:

2x + 8 + 62 = 90

2x + 70 = 90

2x = 90 - 70

2x = 20

x = 20/2

x = 10

Step-by-step explanation:

Total no. of possible outcomes = 6 (1,2,3,4,5,6,)

As given we have only one prime even no. from the above given set, that is 2.

Let's call this event A.

Total no. of favourable outcomes =P(A)= 1

Therefore the probability is  P(A)= 1/6

The equation for the circle O, given the diameter, the secant K and the common point of tangent I, is:

(x - 8)² + (y - 7)² = 15²

(x - 8)² + (y - 7)² = 225

To determine the equation of the circle O with center S(8, 7) and point M(-5, -2) on the secant k, we first need to find the radius of the circle.

Given that the distance from point S to secant k is 5, we can use the Pythagorean theorem to find the length of MA, which is equal to the radius of the circle.

MA² + AS² = MS²

MA² + 5² = MS²

Calculate the distance between points M and S:

MS = √((8 - (-5))² + (7 - (-2))²) = √(13² + 9²) = √(169 + 81) = √250

Now we can find the length of MA:

MA² + 5² = 250

MA² = 250 - 25 = 225

MA = √225 = 15

The equation of a circle with center (h, k) and radius r is given by:

(x - h)² + (y - k)² = r²

Using the given center S(8, 7) and radius 15, the equation of the circle O is:

(x - 8)² + (y - 7)² = 15²

(x - 8)² + (y - 7)² = 225

Picking a male youngster who enjoys playing video games is more likely if you get a score of (4/10) * (6/10) = 24/100 = 6/25.

Probability is a mathematical concept that expresses the possibility or chance of an event happening. It is stated as a number between 0 and 1, where 0 denotes the impossibility of an event and 1 denotes its certainty. By dividing the number of favorable outcomes by the entire number of possible possibilities, the probability of an event is determined.

given

The odds of selecting a male adolescent at random are x/n, while the odds of selecting a teen whose preferred pastime is playing video games are y/n.

As these two occurrences are separate, the likelihood that both will occur is the product of the probabilities:

The odds of selecting a male teen who enjoys video games are (x/n) * (y/n) = xy/n2.

By dividing the numerator and denominator by the greatest common factor (GCF) of x and y, if one exists, this can be made simpler.

A decimal place is a position in a number that is to the right of the decimal point. It represents a fractional part of the number. For example, in the number 3.14159, the digit "1" is in the tenths place, the digit "4" is in the hundredths place, the digit "1" is in the thousandths place, and so on. Each place value to the right of the decimal point represents a power of 10 that is negative, such as tenths, hundredths, thousandths, ten-thousandths, and so on. The number of decimal places determines the degree of precision in the number.

by the question.

To determine the population in the year 2100, we need to calculate how many times the population will double between 2022 and 2100, which is 78 years.

78 years divided by 60 years is approximately 1.3, which means that the population will double 1.3 times between 2022 and 2100.

Answer:

b=46

Step-by-step explanation:

First we know that the sum of all three angles is 180. So that gives us the equation 2b+88=180, then we can solve.

2b=180-88

2b=92

b=46

So that means b=46!

As you may know, a straight line = 180°

Since we already have 88° as one of the values, we can simply subtract that from 180.

180 - 88 = 92

Next, divide 92 by 2

92 ÷ 2 = 46

With that being said, we can conclude that the value of B is 46.

You can double check this by adding all of the values together: 46 + 46 + 88 = 180

Dividing both sides by 2, we get:

x = 6

Therefore, with $4, you can buy 6 Bosc pears.
