Solve: 3|x|+4≥1. Write your solution in interval notation
The solution of the inequality 3|x|+4≥1 in interval notation is {x | -1 ≤ x ≤ 1}.
What is interval notation?An interval on a number line can be represented using interval notation. It is a method of representing subsets of the real number line, in other words. The numbers in between any two particular provided numbers are referred to as an interval. For instance, the interval containing 0, 5, and all values between 0 and 5 is the set of numbers x satisfying 0 x 5.
Given that the inequality is:
3|x|+4≥1
Subtract 4 from both sides of the equation:
3|x| + 4 - 4 ≥ 1 - 4
3 |x| ≥ -3
Divide 3 from both sides of the equation:
|x| ≥ -1
We know that, |x| can be written as x and -x thus,
x ≥ -1
-x ≥ -1 or x ≤ 1
Hence, the solution of the inequality 3|x|+4≥1 in interval notation is {x | -1 ≤ x ≤ 1}.

Question 15 of 30 1 cm -- 2 cm 1 i 3 cm 1 cm 4 cm 4 cm Find the surface area of the above solid.
ANSWER:
The surface area of the above solid is 54 cm^2
STEP-BY-STEP EXPLANATION:
The total surface area of the figure is equal to the sum of the area of all the faces.
In this case it is best to divide the figure in two, as follows:
The total surface area would be the sum of both surface areas.
The surface area of part A would be:
\(\begin{gathered} SA_A=2\cdot l\cdot w+2\cdot l\cdot h+2\cdot w\cdot h \\ \text{ Replacing} \\ SA_A=2\cdot3\cdot4+2\cdot3\cdot1+2\cdot4\cdot1 \\ SA_A=24+6+8 \\ SA_A=38 \end{gathered}\)The surface area of part B would be:
\(\begin{gathered} SA_B=2\cdot1\cdot4+2\cdot1\cdot2+2\cdot1\cdot2 \\ SA_B=8+4+4 \\ SA_B=16 \end{gathered}\)The area of the figure would then be the sum of both areas, like this:
\(\begin{gathered} SA=SA_A+SA_{VB} \\ SA=38+16 \\ SA=54 \end{gathered}\)Solve |x-5| > -2. Write your solution in interval notation.
Answer:
(−∞,∞)
Step-by-step explanation:
Since |x−5| is always positive and −2 is negative, |x−5| is always greater than −2, so the inequality is always true.
All real numbers
So, the answer is (−∞,∞)
On average, Nathaniel drinks
4/5 of a 10-ounce glass of water in
2 2/5
hours. How many glasses of water does he drink in one hour? Enter your answer as a whole number, proper fraction, or mixed number in simplest form.
Nathaniel drinks 3 glasses of water in one hour.
To find out how many glasses of water Nathaniel drinks in one hour, we need to calculate his drinking rate per hour.
In 2 2/5 hours, Nathaniel drinks 4/5 of a 10-ounce glass of water.
Let's convert the mixed number of hours to an improper fraction:
\(2\frac{2}{5} = \frac{(5 \times2 + 2)}{5}\)
\(=\frac{12}{5}\)
Now, we can set up a proportion to find his drinking rate per hour.
We know that \(\frac{12}{5}\) hours corresponds to \(\frac{4}{5}\) of a glass of water.
Let's assign "x" as the number of glasses he drinks in one hour.
The proportion is then
\(\frac{(\frac{12}{5} hours) }{(x glasses) } =\frac{(\frac{4}{5} glass)}{(1 hour)}\)
Cross-multiplying gives us
\((\frac{12}{5} )\times1=\frac{4}{5}\times(x)\)
Simplifying, we get
\(\frac{12}{5} =\frac{4}{5}\times x\)
Dividing both sides by \(\frac{4}{5}\), we find x:
\(x=\frac{(\frac{12}{5} )}{\frac{4}{5} }\)
\(x=\frac{12}{4}\)
\(x = 3.\)
Therefore, Nathaniel drinks 3 glasses of water in one hour.

Step-by-step explanation:
Each meeting room has 325 chairs.
Since we don't know how many meeting rooms there are, the number is replaced with the variable, m.
An equation is a problem with an equals sign so you need to put what it would equal.
Since you don't know how many meeting rooms there are you use the variable, c which represents the total number of chairs.

The correct option for the given question is c) lim x→a¯ f(x) = f(a) when the function f(x) is said to have jump discontinuity at a point x=a.
What is jump discontinuity?Jump continuity is a concept in calculus that describes the behaviour of a function at a specific point where the function jumps from one value to another value without any intermediate values. In other words, a function is considered jump continuous at a point if the function approaches a finite limit from both the left and right sides of that point, but the function values on the left and right sides of the point are not equal.
According to the given information:
The correct notation for the left-hand limit as x approaches a from the left side is lim x→a¯, where the horizontal line above the "a" indicates approaching from the left side.
The statement "lim x→a¯ f(x) = f(a)" means that the limit of f(x) as x approaches a from the left side is equal to the value of f(a) at x = a. This indicates that the function f(x) has a jump discontinuity at x = a, where the function jumps from one value to another value at that specific point.

6b-10b = -60+4
-4b = -56
b = -56/(-4)
b = 14
Therefore,
PS = 6b-4 = 6(14)-4 = 84-4 = 80RS = 10b-60 = 10(14)-60 = 140-60 = 80The following selected information was extracted from the records of B Solomon.
1. B Solomon, the owner of Solomon Traders, bought a new Machine for R250 000 on 1 July 2013.
2. On 1 October 2014, he purchased a second Machine for R350 000 cash.
3. On 30 June 2015, the Machine bought during 2013 was sold for R120 000 cash.
4. It is the business’ policy to depreciate Machines at 20% per annum on cost.
REQUIRED:
Prepare the following ledger accounts reflecting all applicable entries, in the books of Solomon Traders, properly balanced/closed off, for the years ended 31 March 2016:
1.1. Accumulated depreciation.
1.2. A Machines realisation.
NB: Show all calculations as marks will be awarded for calculations.
1.1. Accumulated depreciation:
The accumulated depreciation for the machine bought on 1 July 2013 would be R150,000 as of 31 March 2016.
1.2. Machine realization:
The machine bought in 2013 was sold for R120,000 on 30 June 2015, resulting in a profit/loss on the sale of R10,000.
1.1. Accumulated Depreciation:
To calculate the accumulated depreciation, we need to determine the annual depreciation expense for each machine and then accumulate it over the years.
Machine bought on 1 July 2013:
Cost: R250,000
Depreciation rate: 20% per annum on cost
Depreciation expense for the year ended 31 March 2014: 20% of R250,000 = R50,000
Depreciation expense for the year ended 31 March 2015: 20% of R250,000 = R50,000
Depreciation expense for the year ended 31 March 2016: 20% of R250,000 = R50,000
Accumulated depreciation for the machine bought on 1 July 2013:
As of 31 March 2014: R50,000
As of 31 March 2015: R100,000
As of 31 March 2016: R150,000
1.2. Machine Realisation:
To record the sale of the machine bought in 2013, we need to adjust the machine's value and the accumulated depreciation.
Machine's original cost: R250,000
Accumulated depreciation as of 30 June 2015: R100,000
Net book value as of 30 June 2015:
R250,000 - R100,000 = R150,000.
On 30 June 2015, the machine was sold for R120,000.
Realisation amount: R120,000
To record the sale:
Debit Cash: R120,000
Debit Accumulated Depreciation: R100,000
Credit Machine: R250,000
Credit Machine Realisation: R120,000
Credit Profit/Loss on Sale of Machine: R10,000 (difference between net book value and realisation amount).

The lengths of two similar figures are 35 ft and 10 ft. What is the scale factor, perimeter ratio and area ratio in simplest form of the first to the second.
The scale factor is 7:2, the perimeter ratio is 7:2, and the area ratio is 49:4.
Scale Factor:
The scale factor represents the ratio of corresponding lengths in similar figures.
In this case, the scale factor is given as 7:2.
Perimeter Ratio:
The perimeter ratio of two similar figures is equal to the ratio of their corresponding perimeters.
Since the scale factor is 7:2, the perimeter ratio will also be 7:2.
This means that the ratio of the perimeters of the first figure to the second figure is 7:2.
Area Ratio:
The area ratio of two similar figures is equal to the square of the scale factor. In this case, the scale factor is 7:2.
Thus, the area ratio will be (7/2)² = 49/4.
This indicates that the ratio of the areas of the first figure to the second figure is 49:4.

The domain of the function is (-∝, -3) ∪ (-3, +∝)
The range is (-∝, 3) ∪ (3, +∝) and the asymptotes are x = -3 and y = 3
How to determine the domainFrom the question, we have the following parameters that can be used in our computation:
f(x) = 2/(x + 3) + 3
Set the denominator to not equal to 0
So, we have
x + 3 ≠ 0
So, we have
x ≠ -3
As an interval notation, we have
(-∝, -3) ∪ (-3, +∝)
How to determine the rangeHere, we have
f(x) = 2/(x + 3) + 3
When x = -3, we have
f(-3) = undefined + 3
This means that
f(x) ≠ -3
As an interval notation, we have
(-∝, 3) ∪ (3, +∝)
How to determine the asymptotesIn (a), we have
x ≠ -3
This means that
Vertical asymptote: x = -3
In (b), we have
f(x) ≠ -3
This means that
