The two bars | | is used to indicate the function absolute value.
Remember this definition:
| x | = - x if x < 0 and x if x > 0
So, | x | > c =>
x > c or x > - c
Therefore:
|ax - b| > c => ax - b > c or ax - b > - c
That is the third option of the answer list.

Numbers can be written in exponential form with a base of 10. For example, 100 is written as 10^2, 100,000 as 10^5, and 10,000 as 10^4.
Explanation:To write numbers in exponential form, you need to understand the concept of exponential notation which is a way to express a number as a base raised to a power. In each of the given cases, the base is 10.
For 100, there are two zeros following the 1. This means that 100 can be written as 10 to the power of 2, or 10^2.
Similarly, for 100,000, there are five zeros following the 1. This would be written as 10 to the power 5, or 10^5.
Lastly, 10,000, has four zeros following the 1. This would be written as 10 to the power of 4, or 10^4.

The larger of two numbers is one more than four times the smaller number. if the sum of the numbers is 106, find the numbers.
Answers
x + y = 106
4y + 1 + y = 106
5y = 105
y = 21
We have y, so now we can solve for x using either original equation:
x + y = 106
x + 21 = 106
x = 85
To solve the problem, create two equations based on the information given, then solve these equations step-by-step. After calculation, the two numbers are 21 and 85.
Explanation:Given the problem, we can translate and create two equations which are:
The larger number is one more than four times the smaller number. We can express this as: L = 4S + 1 The sum of the numbers is 106. We can express this as: L + S = 106
Step 1: From the first equation, we know that L = 4S + 1. We can substitute this into the second equation in place of L, giving us 4S + 1 + S = 106.
Step 2: Add up, and we get 5S + 1 = 106. Subtract 1 from both sides and we get 5S = 105.
Step 3: Divide both sides by 5 to solve for S, we get S = 21.
Step 4: Substitute S = 21 into the equation L = 4S + 1, you can calculate and find L = 85.
Therefore, the two numbers are 21 and 85.

Given that, An office uses 478 pounds of paper in one week. The paper comes in packages that hold 18 pounds of paper each.
To find the number of packages of paper, the office use each week, we will divide the total paper used in one week to paper in 1 package

B. x2 – 2x + 4 = 0
C. x2 + 2x – 4 = 0
D. x2 – 2x – 4 = 0
Answers
You can solve this problem 2 different ways.
1. Plug in a value of x = 1 ± √5 into each of the possible equations and see if the result is 0.
or
2. Use the Quadratic formula to solve each of the equations and see which comes up with the correct answer.
For this case, I'll use the 2nd option.
A. x^2 + 2x + 4 = 0
a = 1, b = 2, c = 4
Upon attempting this, you'll quickly discover that you're going to try to get the square root of -12. Since there's no imaginary terms in the desired root, this equation can't be it.
B. x^2 – 2x + 4 = 0
Same issue here, trying to get the square root of a negative number. So this one doesn't work either.
C. x^2 + 2x – 4 = 0
Getting closer. Have (-2 ± sqrt(20)) / 2 = -1 ± √5
Still not it, but closer. At least not trying to get the square root of a negative number.
D. x^2 – 2x – 4 = 0
Since the other 3 are wrong, this must be right. But let's do the math anyway.
a = 1, b = -2, c = -4
The quadratic formula gets (2 ± sqrt(20)) / 2 = (2 ± 2√5)/2 = 1 ± √5
And it works out. So this is the answer.
Assume that lines that appear to be parallel are parallel. Find the value of x and the measure of angle y
Answers
(9x+1)+(14x-34)=180
There, we have an equation we can fairly easily solve for x. What about y?
If we take a look at the line y° occupies, we can see that it shares a straight angle with our (14x-34)° term and - as implied by the right angle on the bottom line - a 90° angle.
All three of these should add up to 180°, so we have:
(14x-34) + y + 90 = 180
Another think to note is that, upon inspection, (14x-34)° and y° are complementary - they add up to 90° - and subtracting the 90 from both sides of our equation confirms that fact:
(14x-34) + y = 90
If you've solved for x prior to this, solving for y should be pretty straightforward.
Answer:
The answer would be (14x-34) + y = 90.

Reflection : Across the line y = 1
Answers
Reflecting across y = 1 means each point's position stays the same horizontally but mirrors vertically across the line.
When reflecting a point or shape across a line, y = 1,
it means that each point is mirrored on the other side of the line while maintaining the same distance from the line.
Here, the line y = 1 acts as a "mirror" or "axis of reflection."
To reflect a point (x, y) across the line y = 1, follow these steps:
Find the vertical distance between the point and the line y = 1. Let's call this distance "d."
If the point is above the line (y > 1), then d = y - 1.
If the point is below the line (y < 1), then d = 1 - y.
Move the point to the same vertical distance on the other side of the line y = 1.
If the point was above the line (y > 1), the new reflected point will be (x, 1 + d).
If the point was below the line (y < 1), the new reflected point will be (x, 1 - d).
Keep in mind that the x-coordinate remains the same in both cases since the line of reflection is vertical (parallel to the y-axis).
By repeating these steps for all points in a shape, obtain the reflection of the entire shape across the line y = 1.

The false statement among the given options is B) 21,730 > 22,341. The greater than, less than symbols should be accurately used to compare two numbers. The other given statements are true.
Explanation:The false statement in the given options is B) 21,730 > 22,341. This statement is saying that 21,730 is greater than 22,341, which is false. In mathematics, '<' symbol represents 'less than' and '>' represents 'greater than'. So, the statement B) is false because 21,730 is not greater than 22,341, but less.
Comparing the following two statements A) 21,730 < 22,341 and C) 22,341 > 21,730, we can see they are actually the same statement, restated in a different manner. Both statements are saying that 21,730 is less than 22,341 which is true.
