What is a number line?A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.
This ultimately implies that, a number line can be used to determine the difference between two numbers such as 23 and 12. Also, a number line typically increases in numerical value towards the right and decreases in numerical value towards the left.
Now, we can determine the distance as follows:

Write the absolute value function as a piecewise-defined function with linear parts.
f(x)=4x+5
The absolute function f(x) = 4x+5 as a piecewise-defined function is:
f(x) = { -4x-5 , x<-5/4
4x+5 , x ≥-5/4 }
Given, the absolute function f(x) = 4x+5
The fundamental tenet of piecewise linear regression is that we should construct the regression function in "pieces" if the data exhibit various linear trends over various parts of the data. The components may or may not be joined.
when 4x+5 < 0
4x < -5
x < -5/4
f(x) = -(4x+5) = -4x-5
when 4x+5 ≥ 0
4x ≥ -5
x ≥ -5/4
f(x) = 4x+5
so f(x) = { -4x-5 , x<-5/4
4x+5 , x ≥-5/4 }
since, I x I = { -x , x<0
x , x ≥0}
Therefore, we get the required piecewise-defined function with linear parts.

Rachel is making premade 3-inch by 5-inch tile rectangles for her driveway. If it takes her 6 minutes to position each rectangle, how many hours will it take her to create a 2-foot by 4-foot pattern drive? Write your answer as a decimal.
Answer:
Tile a rectangle with unit squares. It is 8 unit squares long and 7 unit squares wide. Each unit square represents one square inch.
Step-by-step explanation:
The time taken to create a 2-foot by 4-foot pattern drive is 38.4 minutes.
What is a unit rate?A unit rate means a rate for one of something.
It is written as a ratio with a denominator of one.
We have,
A rectangle tile area = 3-inch by 5-inch
Area = 15 inches
Time taken to position 15 inches tile = 6 minutes.
We can write as,
15 inches = 6 minutes _____(1)
We have a 2-foot by 4-foot pattern drive.
Area = 8 feet
We know that,
1 foot = 12 inches
Multiply both sides by 8.
8 feet = 8 x 12 inches
8 feet = 96 inches _______(2)
Now,
From (1) and (2) we get,
15 inches = 6 minutes
Multiply 96/15 on both sides we get,
96/15 x 15 inches = 96/15 x 6 minutes
96 inches = 38.4 minutes
Thus the time taken to create a 2-foot by 4-foot pattern drive is 38.4 minutes.

Find the coordinates of J if K(-2, 6) is the midpoint of JL and L has coordinates (-1, -3).
The the coordinates of endpoint J on line segment JL with a midpoint of (-2, 6) is ( -3,15 ).
How determine the a second endpoint from a point and a midpoint?A midpoint is simply a point that divides a line segment into two equal halves.
The midpoint formula is expressed as;
M = ( (x₁+x₂)/2, (y₁+y₂)/2
Given the data in the question;
Midpoint K(-2, 6)
x = -2y = 6Point L(-1, -3).
x₂ = -1y₂ = -3Point J
x₁ = ?y₁ = ?To determine the coordinate of point J, plug the given points into the midpoint formula above and simplify.
First, we get the x-coordinate of point J
x = (x₁+x₂)/2
2x = x₁ + x₂
2( -2 ) = x₁ + ( -1 )
-4 = x₁ - 1
x₁ = -4 + 1
x₁ = -3
Next, we get the y-coordinate of point J
y = (y₁+y₂)/2
2y = y₁ + y₂
2(6) = y₁ + (-3)
12 = y₁ - 3
y₁ = 12 + 3
y₁ = 15
Therefore, the coordinates (x₁,y₁) of the endpoint point J is ( -3,15).

Mason and his children went into a movie theater and he bought $36.50
worth of candies and pretzels. Each candy costs $4.25 and each pretzel costs
$3.50. He bought 6 more pretzels than candies. Write a system of equations
that could be used to determine the number of candies and the number of
pretzels that Mason bought. Define the variables that you use to write the
system.
Answer:
4.25c + 3.5p = 36.50
c + 6 = p
c = candies and p = pretzels
Step-by-step explanation:
So for the first equation, the prices will be the coefficients of each variable, since for each candy/pretzel it will be that price. We also know that both of these prices together equal 36.50, so that will be on the other side of the equal sign. So the equation representing this info is 4.25c + 3.5p = 36.50
And for the second equation I saw that Mason bought 6 more pretzels than candies. So no matter what number the candies is, the pretzels should always be 6 more than the candies. So the equation representing this information is c + 6 = p
Lastly I just defined the variables that I used to right the system. That is all! Hope this helps you this should be correct :)

The weight of a person in Venus who weighs 210 pounds on Earth is 185.5 pounds.
It is given in the question that weight of a person on Venus varies directly with his or her weight on Earth. Also, a person weighing 120 pounds on Earth weighs 106 pounds on Venus.
We have to find the weight of the person in Venus who weighs 210 pounds on Earth.
Let weight on Earth be e and,
weight on Venus be v.
From the data given in the question, we can write,
e ∝ v
e = kv
Where k is the constant of proportionality
120 = k*106
k = 120/106 = 60/53
Hence, we can write,

The probability that it is a female with long hair is 0.75 .
Potential is described by probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability generally refers to the degree to which something is likely to occur. Gonna determine how likely something is to occur, use probability. Many things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty. Every event's probability in a sample space is one.
the likelihood of an occurrence, E is
P(E) = The proportion of positive outcomes to all outcomes.
In probability, an event is said to be independent if it is completely unaffected by the occurrence of any other event, and it is considered to be dependent if it is affected by other occurrences.
Using the literature and formulas mentioned above, we have:
Let F stand for the circumstance that the student is a female and L for the circumstance that the student has long hair.
In this illustration, the probability are as follows:
P(F) = 0.60; P(L) = 0.50
P(F AND L) = 0.45 and P(L|F) = 0.75 as a result.

Needing some help, been working on this for a while now.
Answer:
x = 15
z = 64
Step-by-step explanation:
Lets make an equation -
(14x - 94) + z = 8x - 4 +z
Both sides are parallel to each other, and therefore the sum is also 180.
Then we solve it -
14x - 8x - 94 + z = -4 + z
Bring the z on the other side to eliminate it.
6x - 94 = - 4
Add 94 on both sides
6x = 90
Divide 6 on both sides and you get x = 15
Substitute x into 8x -4 + z = 180
8*15 - 4 + z = 180
120 - 4 + z = 180
116 + z = 180
Subtract 116 on both sides.
z = 64.

Answer:
Step-by-step explanation:
1. To find the value of x, you'll need to set 14x-94 equal to 8x-4. We do this since the two angels are congruent, and congruent angles are equal to each other:
[tex]14x-94=8x-4[/tex]
You'll then solve for x by isolating the x value.
[tex]14x-8x=94-4[/tex]
[tex]6x=90[/tex]
[tex]x=\frac{90}{6}[/tex]
[tex]x=15[/tex]
2. To find z I would plug in the x value to one of the equations, such as 8x-4, in order to find the measure of that angle:
[tex]8(15)-4\\=116[/tex]
We now know that 14x-94 and 8x-4 are equal to 116. To find z you'll add the angle opposite to it, the blank angle since they are congruent. Now you'll add all the angles together and set the equation equal to 360:
[tex]z+z+116+116=360\\2z+232=360\\2z=(360-232)\\2z=128\\\frac{2z}{2} =\frac{128}{2} \\z=64[/tex]
Your final answers are x=15 and z=64, hope this helps!
