Solve the compound inequality, graph the solution set, and write in interval notation. SHOW ALL STEPS! 6x - 3x + 12 or 5x – 6 > 3x + 2
Answer
- The solution of this compound inequality is x < 3 OR x ≥ 4
- The graph of this solution is attached below
- The interval notation is (-∞, 3) OR [4, ∞)
Explanation
The compound inequality to be solved is
6x - 3 < x + 12 OR 5x - 6 ≥ 3x + 2
To solve this, we solve each of the pair one at a time for the two-part solution
6x - 3 < x + 12
6x - x < 12 + 3
5x < 15
Divide both sides by 5
(5x/5) < (15/5)
x < 3
OR
5x - 6 ≥ 3x + 2
5x - 3x ≥ 6 + 2
2x ≥ 8
Divide both sides by 2
(2x/2) ≥ (8/2)
x ≥ 4
So, the solution is
x < 3 OR x ≥ 4
So, this solution says that x is less than 3, but greater than or equal to 4.
For the graph, Note that
In graphing inequality equations, the first thing to note is that whenever the equation to be graphed has (< or >), the circle at the beginning of the arrow is usually unshaded.
But whenever the inequality has either (≤ or ≥), the circle at the beginning of the arrow will be shaded.
This solution tells us that the wanted parts are numbers less than 3 and numbers greater than 4.
Also, in writing inequalities as interval, the signs (< or >) indicate an open interval and is written with the bracket () while the signs [≤ or ≥] denote a closed interval which is denoted by the brackets [].
x < 3, that is, x ranges from negative infinity to just before 3.
x < 3 is (-∞, 3)
x ≥ 4, that is, x ranges from 4 to infinity
x ≥ 4 is [4, ∞)

I've always wondered why we put the dollar sign ($) before a number, when, when we say an amount of money we say the number first then dollars; like $12, but I think it really should be 12$, cause we don't go and say "dollar twelve", we say "twelve dollars". I don't know if this makes sense, but this always confused me; please share your thoughts.
Answer: I believe it's just custom. Some nations follow the quantity with a currency symbol, such as the dollar sign.
According to one hypothesis I've heard, the currency symbol was added before the quantity to stop individuals from modifying handwritten amounts, like changing 25.00 into 125.00, for example. It might be accurate, however I believe that the amount is always spelled out in words in the majority of situations when such fraud would be conceivable, such as on checks.

How are the least common multiple and the least common denominator related?
Least common denominator is the lowest number to which all the fractions can be expanded, so it is the Least common multiple of all denominators.
Given that,
We have to find the difference of LCD and LCM.
What is LCM?The least common multiple, or LCM, is the smallest common multiple of any two or more numbers. What does "common" mean? In this context, the word "common" refers to something that is shared by two or more people.
What is LCD?The LCD, or least common denominator, is the least common multiple of two or more denominators. In this instance, the denominator, or bottom number, of a fraction contains the common multiple. When arithmetically adding or subtracting fractions, the LCD must be computed. When dividing or multiplying fractions, the LCD is not required.
For example,
Let's check the following fractions:
(1/2,2/3,5/6)
To find the Least common denominator of the fractions we have to find the Least common multiple of the fractions' denominators:
lcd(1/2,2/3,5/6)=lcm(2,3,6)
To calculate the Least common multiple we have to find the lowest number which can be obtained by multiplying those numbers.
This number is 6 because we can multiply 2×3 and 3×2 to get 6.
Therefore, Least common denominator is the lowest number to which all the fractions can be expanded, so it is the Least common multiple of all denominators.

Consider the line 8x-2y=-5.
Find the equation of the line that is parallel to this line and passes through the point (-4, 3).
Find the equation of the line that is perpendicular to this line and passes through the point (-4, 3).
Answer:
4x - y = - 19 and x + 4y = 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
8x - 2y = - 5 ( subtract 8 from both sides )
- 2y = - 8x - 5 ( divide through by - 2 )
y = 4x + [tex]\frac{5}{2}[/tex] ← in slope- intercept form
with slope m = 4
• Parallel lines have equal slopes , then
y = 4x + c ← is the partial equation
to find c substitute (- 4, 3 ) into the partial equation
3 = - 16 + c ⇒ c = 3 + 16 = 19
y = 4x + 19 ← equation of parallel line in slope- intercept form
subtract y from both sides
0 = 4x - y + 19 ( subtract 19 from both sides )
- 19 = 4x - y , that is
4x - y = - 19 ← equation in standard form
----------------------------------------------------------------------
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{4}[/tex] , then
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
to find c substitute (- 4, 3 ) into the partial equation
3 = 1 + c ⇒ c = 3 - 1 = 2
y = - [tex]\frac{1}{4}[/tex] x + 2 ← equation of perpendicular line in slope- intercept form
multiply through by 4 to clear the fraction
4y = - x + 8 ( add x to both sides )
x + 4y = 8 ← equation in standard form
13) Solve the following quadratic equations by completing the square: X^2 + 16x + 5 = 0
We want to solve the following equation
x² + 16x + 5 = 0
↓
x² + 16x = 5
We want to rewrite the equation so its left side is
(x + a)²
We know that
(x + a)² = x² + 2ax + a²
where a is a number, then, we want that the left side look something like
x² + 2ax + a²
Then we first want to find which must be the number a in this case.
Finding aSince 2 · 8 = 16, then the left side is
x² + 16x = x² + 2 · 8x
then, in this case a would be 8
a = 8
Completing the square with a²We want that the left side of our equation looks like:
x² + 2ax + a²
Since it has the first two terms
x² + 16x = 5
we have to add a² = 8² = 64
We add it both sides of the equation:
x² + 16x + 8² = 5 + 64
x² + 2 · 8x + 8² = 69
Now, we can write it as (x + a)²
x² + 2 · 8x + 8² = 69
↓ since (x + a)² = x² + 2ax + a²
(x + 8)² = 69
Solving the equationIn order to solve the equation, we want to "leave x alone" on the left side:
(x + 8)² = 69
↓ squaring root both sides
(x + 8) = ±√69
x + 8 = ±√69
↓ taking 8 to the right side
x = - 8 ±√69
SolutionsWe have two solutions:
x₁ = - 8 -√69
x₂ = - 8 + √69

Line f passes through 4, 0) and is parallel to a line that passes through (7, -3) and (-10. -2)
A straight line can be written in the form of a two variable linear equation.
The equation of line passing through point (4,0) is y = -1 / 17 x + 4.
How to represent a straight line on a graph?To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.
Given that,
The line is passing through the point (4,0).
It is parallel to the line passing through (7, -3) and (-10. -2).
The slope of the line passing through (7, -3) and (-10. -2) is
m₁ = (-2-(-3)) / (-10 - 7)
m₁ = - 1 / 17
Since the slope of two lines parallel to each other is equal, the slope of the line passing through point (4,0) is - 1 / 17.
Thus, the equation of line passing through point (4,0) can be written as,
(y - 4) / (x - 0) = - 1 / 17
=> y = -1 / 17 x + 4
Hence, the equation of the given line is y = -1 / 17 x + 4.

1 print is equal to 2 cups or 16 fulid ounces how many fulid onces are in 4 prints 3 cups
Answer:
There would be 88 fluid ounces in 4 prints and 3 cups.
Step-by-step explanation:
So, if 1 print is equal to two cups, and we have 4 prints, that would mean we can multiply 4 x 2, which equals 8 cups. Now that the prints are out of the way, we add the 3 cups still remaining, to get 11 cups. Now, it wants us to find the fluid ounces, which 16 fluid ounces are in 2 cups, so, 11 divided by 2 = 5.5. So, 5.5 x 16 = 88 fluid ounces.

The shaded region for the inequality is below the line. Find the inequality represented by the graph.
The linear inequality that represented by the graph is given as follows:
y < -4x/3 + 5.
How to obtain the inequality?The inequality is represented by a line, which has the following format:
y = mx + b.
In which the coefficients of the equation of the line are listed as follows:

How do you find the distance between the points shown
Answer:
A. Subtract the distance between each point and the x-axis.
Step-by-step explanation:
The points shown are horizontally distanced. Because of this, you need to subtract their x values. In coordinate planes, the variable "x" represents how far a point is or is not from the origin. Given this information, you need to subtract the x values to get the distance they are apart. Note: Distance on a number line or graph is always given in absolute value. Absolute value is the term for when a number is converted to its positive form. For instance, |-1| has these brackets around it representing absolute value. Whenever a number in absolute value is a negative number or is greater than 0, it will become its positive form. |-1| = 1
Hope this helps!
Option A is correct, By subtracting the distance between each point and the x axis we find the distance between the points shown
What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
The given two points in the given graph are A(-8, -4) and B(2,-4)
Now let us plug in these points in the formula.
x₂= 2, x₁ = -8, y₂=-4, y₁=-4

What i the equation of a line that pae through the point (4,−17) and i perpendicular to y=x/7−3? Enter your anwer in the box
The equation of the line that is passing through the point (4,−17) and is perpendicular to y=x/7−3 is 7x -y = -30.
The line is passing through the point (4,-17) and is perpendicular to the line y = x/7-3
Now, the slope of the given line y = x/7-3 is,
M = 1/7
If the other line is perpendicular to it and has slope m, then the, we can write,
Mm = -1
So, putting values,
(1/7)m = -1
m = -7
Now, we have the slope m = -7 of the line and the point (4,-17) of the line,
So, the equation of the line will be,
m = [y-(-17)]/[x-4]
-7 = y+17/x-4
