What is the numerical length of segment LN?A line segment is simply the part of a line that connects two points or is bounded by two points.
Given the data in the question;
Point M is on line segment LNSegment LN = 4xSegment MN = xSegment LM = 3Numerical length of segment LN = ?Since point M is on line segment LN, segment LN equals to the sum of segment LM and MN.
Hence;
Segment LN = segment LM + segment MN
4x = 3 + x
Solve for x
4x - x = 3
3x = 3
x = 3/3
x = 1
Now, we find the numerical length of segment LN;
Segment LN = 4x
Plug in x = 1 and simplify
Segment LN = 4( 1 )
Segment LN = 4
Therefore, the length of segment LN is 4.

Step-by-step explanation:
[tex] \frac{1}{a + b} \times ( \frac{a + b}{ab}) = \frac{1}{ab} [/tex]
Answer with step-by-step explanation:

First, convert these into positive indices.
[tex]\frac{1}{(a+b)} *(\frac{1}{a} +\frac{1}{b})=\frac{1}{ab}[/tex]
And now, let us solve the left side.
[tex]\frac{1}{(a+b)} *(\frac{1}{a} +\frac{1}{b})\\\\[/tex]
First, solve the brackets. That is add the fractions inside the brackets.
[tex]\frac{1}{(a+b)} *(\frac{1}{a} +\frac{1}{b})\\\\\frac{1}{(a+b)}*(\frac{1*b}{a*b} +\frac{1*a}{b*a})\\\\\frac{1}{(a+b)}*(\frac{b}{ab} +\frac{a}{ab})\\\\\frac{1}{(a+b)}*\frac{(a+b)}{ab}[/tex]
Now multiply the fractions.
[tex]\frac{1}{ab}[/tex]
So, it's clear that the left side equals the right side.

The function which will represent the given Translation will be T(x, y) = (x + 3, y - 2).
Translation may be defined as the shifting of the curve on a graph or shifting of the plotted points on a graph. The translation can be horizontal or vertical. In horizontal direction it can be shifted either left or right and in vertical direction it can be shifted either up or down. Horizontal translation always occurs on the x axis and vertical translation always occurs on the y axis. A function may be defined as an expression in which for input variable x there is output variable y. We need to translate a function T(x, y) 3 units right so the new coordinate will be T(x + 3, y). Now, translation occurs 2 units down. so, new coordinates will be T(x + 3, y -2) which is the required function.

HELP PLS Write the equation of the line in fully simplified slope-intercept form.
The equation of the line that passes through the x-intercept ( -2,0 ) and y-intercept ( 0,1 ) is y = (1/2)x + 1.
What is the equation of line of the graph?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
From the graph, the x and y-intercept are; ( -2,0) and (0,1 )
Point 1 ( -2,0 )
x₁ = -2y₁ = 0Point 2( 0,1 )
x₂ = 0y₂ = 1First, we determine the slope of the line.
Slope m = y₂ - y₁ / x₂ - x₁
Slope m = 1 - 0 / 0 - (-2)
Slope m = 1 / 0 +2
Slope m = 1/2
Next, determine the y-intercept b by substituting the slope and a point into the equation of line formula.
y = mx + b
0 = (1/2)(-2) + b
0 = -2/2 + b
0 = -1 + b
b = 1
Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = (1/2)x + 1
Therefore, the equation of the line is y = (1/2)x + 1.

Julia must sell no less than $330 worth of tacos and burritos each day. If 42 burritos were sold, determine all possible values for the number of tacos that Julia must sell in order to meet the requirements. Your answer should be a comma separated list of values.

find the measures for angles one and two
The measure of the angles x and y are 71 degrees and 109 degrees after applying the concept of vertically opposite angles.
What are vertically opposite angles?
It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
From the figure:
The value of y can be found by applying the concept of vertically opposite angles:
y = 109 degrees
x = [360 - 2(109)]/2
x = (360 - 218)/2
x = 71 degrees
Thus, the measure of the angles x and y are 71 degrees and 109 degrees after applying the concept of vertically opposite angles.

closed circles are at negative 2 and positive 8. everything between the points is shaded.
We have the equation:
|h - 3| [tex]\leq[/tex] 5
Remember that the equation:
|f(x)| = A
with A > 0
means that:
f(x) = A
or
f(x) = -A
Then for our case, we can rewrite:
|h - 3| [tex]\leq[/tex] 5
as:
(h - 3) [tex]\leq[/tex] 5
or
-(h - 3) [tex]\leq[/tex] 5
Now we can solve these two equations to find the two possible values of p.
From the first one, we get:

The function f(x) = 210-60x represents a second trip, where f(x) is the number of miles
the car is from its destination after x hours. Which trip takes less time? Explain.
Answer:
the trip represented by f(x) takes less time
Step-by-step explanation:
Given a table of time and distance to go, and a function f(x) = 210-60x representing the same for a different trip, you want to know which trip takes less time.
TableThe table has values ...
(time in hours, remaining distance in miles) = (1, 150), (2, 100), (3, 50)
This shows you the remaining distance decreases by 50 miles for every hour added to the travel time. That means the remaining 50 miles will be reduced to zero after 4 hours.
The trip represented by the table takes 4 hours.
EquationThe function f(x) = 210-60x will have a value of zero when ...
0 = 210 -60x
0 = 3.5 -x . . . . . . divide by 60
x = 3.5 . . . . . . . . add x
The trip represented by the function f(x) takes 3.5 hours.
The second trip takes less time.

e. Check your answer.
Help Please write it simple
Using a system of equations, it is found that:
b) The domain of the solution is that Steve ran 11 miles.
c) Variable S gives the distance ran by Steve.
d) The algebraic expressions are: K = 4 + S, K + S = 26.
e) The equation is: 4 + S + S = 26.
What is a system of equations?
A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.
In the context of this situation, the variables are given as follows:
Variable K: Distance ran by Kevin.
Variable S: Distance ran by Steve.
Kevin ran 4 miles more than Steve ran, hence:
K = 4 + S.
The sum of their distances is 26 miles, hence:
K + S = 26.
Replacing the first equation K = 4 + S on the second, we have that:
4 + S + S = 26
2S = 22
S = 11 miles.
