Which values of k are solutions to the inequality StartAbsoluteValue negative k minus 2 EndAbsoluteValue less-than 18? Check all that apply.
Answers
Answer:
You could just replace all the given possible values of k in the inequality and see which ones are solutions, but let's solve this in a more interesting way:
First, remember how the absolute value works:
IxI = x if x ≥ 0
IxI = -x if x ≤ 0
Then if we have something like:
IxI < B
We can rewrite this as
-B < x < B
Now let's answer the question, here we have the inequality:
I-k -2I < 18
Then we can rewrite this as:
-18 < (-k - 2) < 18
Now let's isolate k:
first, we can add 2 in the 3 parts of the inequality:
-18 + 2 < -k - 2 + 2 < 18 + 2
-16 < -k < 20
Now we can multiply all sides by -1, remember that this also changes the direction of the signs, then:
-1*-16 > -1*-k > -1*20
16 > k > -20
Then k can be any value between these two limits.
So the correct options (from the given ones) are:
k = -16
k = -8
k = 0

A conveyor belt at a recycling center is 294 feet long. The belt moves 7 feet in 6 seconds. A sorter calculates that it
takes 343 seconds for an object to travel the length of the belt. He places his plastic water bottle at the start of the belt so he can tie
his shoe. He walks to the end of the belt before 343 seconds pass. His bottle is already in the shredder. How many seconds does it
take the water bottle to travel the length of the belt? What is the sorter's error?
Answers
The sorter's error is 91 seconds. This means that the sorter miscalculated the time it would take for the water bottle to travel the length of the belt by 91 seconds.
What lengths are examples of?When anything is referred to as being "long," it refers to its overall length. In other words, it is the larger of the third or upper two dimensions of a geometric object. An example of a shape with two dimensions is a rectangle.
To find out how many seconds it takes for the water bottle to travel the length of the belt, we can use the equation:
distance = rate x time
We know the distance (294 feet) and the rate (7 feet per 6 seconds). Let's solve for time:
294 feet = (7 feet/6 seconds) x time
294 feet x 6 seconds = 7 feet x time
1764 seconds = 7 feet x time
time = 1764 seconds / 7 feet
time = 252 seconds
So it takes 252 seconds for the water bottle to travel the length of the belt.
Now let's calculate the sorter's error:
343 seconds - 252 seconds = 91 seconds
The sorter's error is 91 seconds. This means that the sorter miscalculated the time it would take for the water bottle to travel the length of the belt by 91 seconds.

What is linear regression?In general, to find the equation of a trend line in a scatter plot, you can use linear regression. Linear regression is a statistical method that finds the line of best fit through a set of data points. The equation of the trend line can then be written in the slope-intercept form, y = mx + b, where "m" is the slope of the line and "b" is the y-intercept.
The yellοw pοints are lοcated at the pοints (1, 0) and (8, 7)
Fοr a linear equatiοn that pases trοugh the pοints (x1, y1) and (x2, y2), the slοpe is:
s = (y₂ - y₁)/(x₂ - x₁)
Then, fοr οur equatiοn, the slοpe is
s = (7-0)/(8-1) = 1
Then οur linear equatiοn is
y = 1 × x + b
where b is the y-axis intercept.
Tο find b, we can use that when x = 1, y = 0

Answers
The result is positive, Tori made a capital gain of $1,839 from the sale of the Mattel stock.
What is selling price ?
The selling price is the amount of money at which a product or service is sold to the customer. It is the price that the customer pays to purchase the product or service from the seller. The selling price is usually determined by considering various factors such as the cost of production, overhead expenses, marketing expenses, and the desired profit margin. The seller may also take into account the competition in the market and adjust the selling price accordingly.
According to given information :To calculate Tori's capital gain or loss, we need to find the difference between the amount she sold the shares for and the amount she bought them for.
Tori bought 300 shares of Mattel stock for $34.87 per share, so her initial investment was:
300 x $34.87 = $10,461
She later sold all of the shares for $41 per share, so she received:
300 x $41 = $12,300
To find her capital gain or loss, we subtract her initial investment from the amount she received from the sale:
$12,300 - $10,461 = $1,839
Since, the result is positive, Tori made a capital gain of $1,839 from the sale of the Mattel stock.

2 3/4 of 500grams in step by step calculator
Answers
Answer:
To calculate 2 3/4 of 500 grams, follow these steps:
1. Convert the mixed number to an improper fraction:
2 3/4 = (2 x 4 + 3)/4 = 11/4
2. Multiply the improper fraction by 500:
11/4 x 500 = (11 x 500)/4 = 2,750/4
3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:
2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2
Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

Step-by-step explanation:
You want to know which of the given points satisfies the inequality.
GraphWe find it easiest to plot the given points on a graph of the solution. This shows us that (1, 2) is a solution to the inequality. (It lies in the solution area.)
__
Additional comment
Another way to choose the answer is to try each of the points in the inequality.
If you can visualize the boundary line (without plotting it) as a line with positive slope and a y-intercept of 2, you can more readily reject the first choice and accept the last choice. (0, 3) is above the y-intercept, and (1, 2) is to the right of it (in the solution space).
You may also recognize the x-intercept will be -3, so the second choice lies above the boundary line.

The value of x is 30°
How to find the value of x?
Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.
(5w+20)° + 3w° = 180° (sum of angles on a straight line is 180° )
5w +20 + 3w = 180
8w + 20 = 180
8w = 180 - 20
8w = 160
w = 160/8
w = 20°
3w° + 4x° = 180° (sum of angles on a straight line is 180° )
3w + 4x = 180
Put w = 20 and solve for x:
3(20) + 4x = 180
60 + 4x = 180
4x = 180 - 60
4x = 120
x = 120/4

- We cannot determine the domain of f(x) or h(x) from the given table but we can see that g(x) has a domain of all real numbers.
- We can see that g(x) has the highest maximum value among the three functions, which is 8.
- We cannot determine the range of f(x) or g(x) from the given table but we can see that h(x) has a range of all negative numbers.
- We cannot say anything about the domain or range of f(x) based on the given table.
- Therefore, the two statements that can be used to compare the characteristics of the functions are: g(x) has the greatest maximum value and all three functions share the same domain.

what is the value of x^2 - 6x + 9 when x = 2 + i?
Answers
The Expression x^2 - 6x + 9 when x = 2 + i is -2i
To evaluate the expression x^2 - 6x + 9 when x = 2 + i, we substitute the value of x into the expression:
(2 + i)^2 - 6(2 + i) + 9
Simplifying the first term, we get:
(2 + i)^2 = 2^2 + 2(2)(i) + i^2 = 4 + 4i + i^2
Since i^2 = -1, we can substitute that in and simplify further:
(2 + i)^2 = 4 + 4i - 1 = 3 + 4i
Now we substitute this into the original expression:
(2 + i)^2 - 6(2 + i) + 9 = (3 + 4i) - 6(2 + i) + 9
Simplifying further, we get:
= 3 + 4i - 12 - 6i + 9
= 0 - 2i
= -2i
Therefore, the value of x^2 - 6x + 9 when x = 2 + i is -2i.
