Congruent segments are LK=MK, LK=7x-10, KN=x+3, MN=9x-11, and KJ=28, the LJ will be-
LJ = 18 + 28 = 46
LJ = 18 + 28 = 46
These are Congruent segments
Let J, K, L, M, N are points on the same line.
MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14
As LK = MK and LK = 7x - 10, then
7x - 10 = 8x - 14
8x - 7x = -10 + 14
x = 4
LJ = MK + KJ
MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18
LJ = 18 + 28 = 46
Congruent segments are segments which have the equal length. ≅ points that lie at the equal line are called collinear.
A theorem is a mathematical assertion that can be proved. The midpoint of a phase is a point that divides the phase into two congruent segments
If three or more points lie on a single straight line, they are said to be collinear. An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two points determine a line, two points are trivially collinear.
Two line segments are congruent if they have the same length. They do not need to have the same position or orientation

Assuming that the line segments CE and FH are parallel, then:Angle W
Here we have Opposite Angles by Vertex, so
W = 14
According to the attached figure, the angle W is also corresponding, so in the triangle CEG one of the angles will be 14°
Angle Z
The sum of the interior angles of a triangle is 180°, so for triangle CEG:
Z + W + 78 = 180
Z + 14 + 78 = 180
Z = 88
Angle X
Z and 4X are complementary angles, then
Z + 4X = 180
88 + 4X = 180

A parachutist's rate during a free fall reaches 70 meters per second. What is this rate in feet per second? At this rate, how many feet will the parachutist fall during 2 seconds of free fall? In your computations, assume that 1 meter is equal to 3.3 feet. Do not round your answers.
The rate of feet per second is 231 ft/sec and parachutists will fall 462 ft in 2 seconds.
What do we mean by speed?The definition of speed is The rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling. Because it has only one direction and no magnitude, speed is a scalar quantity.So, let's assume that y70m/s is the terminal velocity.
As 1 meter = 3.3 feetThen, 70 meters = 70 × 3.3 = 231 ft/secParachutist will fall at what rate in 2 seconds: 462 ft/secTherefore, the rate of feet per second is 231 ft/sec and parachutists will fall 462 ft in 2 seconds.

Can you use absolute value when subtracting two negatives?
- 2 1/2 - (-1 2/3)
or does it only work when one number is negative?
Yes, it is possible to use absolute value when subtracting two negatives and as such it does not only work when one number is negative.
How to Interpret Absolute Values?
When adding two negative numbers, add the absolute value of the numbers and keep the negative sign.
For example -1 + -2 = - (||-1| + |-2||), which is -(1 + 2) or -3
The absolute value when subtracting two negatives is -2¹/₂ - (-1²/₃) is possible because when subtracting, we will change the subtraction to addition and change the sign of the number being taken away.
Thus, we can conclude that it is possible to use absolute value when subtracting two negatives.

In linear equation 109333.2 dollars is the average yearly salary of an individual with each of these final degrees .
What is a linear equation ?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.let x be the salary of individual with bachelor degree
Then the average salary of individual with Masters degree is:
(2x-40000)
the combined of two salaries is 130000:
x+(2x-40000)=130000
3x-40000=130000
3x=130000+40000
x=170000/3
x = 56,666.66
x= 56,666.6 dollars ( the average salary of bachelor degree)

One number is 3 less than 6 times a second number.
Their sum is 46. Find the numbers
If × represents the second number, which equation is
correct for solving this problem?
Step-by-step explanation:
y is the second number. This means we can define it as the following equations where x is the second number:
y=6x-3
y+x=46
we have a system of equations, let's move all x to the right side
y=6x-3
y=46-x
this means that 6x-3=46-x
6x+x=46+3
7x=49
x=7

Use the inverse of the coefficient matrix to solve the system of equations.

2x+3y+4z = -10
−x−4y−8z = −66
Answer:
(x, y, z) = (-62, 50, -9)
Step-by-step explanation:
You want the solution to this system of equations using the inverse of the coefficient matrix.
x+2y+3z = 11
2x+3y+4z = -10
−x−4y−8z = −66
Inverse matrixThe inverse of the coefficient matrix is the transpose of the cofactor matrix, divided by the determinant. There are some shortcuts that can be used to make the computation easier. Easiest is letting a calculator find the matrix inverse. (See the first attachment.)
SolutionThe solution to the set of equations is the product of the inverse matrix and the constant vector on the right of the equal signs. That, too, can be found using a calculator. (See the second attachment.)
The solution is (x, y, z) = (-62, 50, -9).
4.30. An internet service provider has two connection lines for its customers. Eighty percent of

Line I has a Gamma connection time with parameters a = 3 and λ = 2 min-¹. Line II has
a Uniform(a, b) connection time with parameters a = 20 sec and b = 50 sec. Compute the
probability that it takes a randomly selected customer more than 30 seconds to connect to
the internet.
Using the uniform distribution, there is a 0.6667 = 66.67% probability that it takes a randomly selected customer more than 30 seconds to connect to the internet.
What is the uniform probability distribution?It is a distribution with two bounds, given by a and b, in which each possible outcome is equally as likely.
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
For this problem, the connection time has parameters a = 20 sec and b = 50 sec, as stated in the problem.
The probability that it takes a randomly selected customer more than 30 seconds to connect to is P(X > 30).
Hence, applying the formula, with the bounds, we have that:
P(X > 30) = (50 - 30)/(50 - 20) = 2/3 = 0.6667.
The measure above is the desired probability.
