Find the equation of the line with the given description.parallel to y = 3x − 4, passes through (5, 4)
Answers
Given the equation of a line:
\(y=3x-4\)You can identify that it is written in Slope-Intercept Form:
\(y=mx+b\)Where "m" is the slope of the line and "b" is the y-intercept.
By definition, parallel lines have the same slope but different y-intercepts. Therefore, you can determine that the slope of the given line and the slope of the line you must find is:
\(m=3\)Because they are parallel.
You know that the other line passes through this point:
\((5,4)\)Then, you can set up:
\(\begin{gathered} x=5 \\ y=4 \end{gathered}\)And substitute the slope and those coordinates into:
\(y=mx+b\)Then, by substituting values into the equation and solving for "b", you get:
\(\begin{gathered} 4=3(5)+b \\ 4=15+b \\ 4-15=b \\ b=-11 \end{gathered}\)Knowing the values of "m" and "b", you can write the equation of the other line in Slope-Intercept Form:
\(y=3x-11\)Hence, the answer is:
\(y=3x-11\)Round to the nearest hundredth (2 decimal places) when necessary

The ratio of the scaled area to the actual area of the patio is 0.1389 square feet : 320 square feet or 1 : 2306.56
What is a scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object,
We have,
The actual dimensions of the patio are 20 feet by 16 feet.
The scale factor is 1 inch to 4 feet,
This means that 1 inch on the scale drawing represents 4 feet in reality.
So the dimensions of the scale drawing are:
20 feet x (1/4) = 5 inches (length on scale drawing)
16 feet x (1/4) = 4 inches (width on scale drawing)
The area of the actual patio is:
= 20 feet x 16 feet
= 320 square feet
The area of the scale drawing is:
= 5 inches x 4 inches
= 20 square inches
The ratio of the area of the scaled drawing to the actual area of the patio is: 20 square inches : 320 square feet
To simplify this ratio, we need to convert both values to the same units.
Converting the area of the scale drawing to square feet:
= 20 square inches x (1/144) square feet/square inch
= 0.1389 square feet
So the ratio of the area of the scaled drawing to the actual area of the patio is:
0.1389 square feet : 320 square feet
Or, in simplified form:
1 : 2306.56
Thus,
The ratio of the scaled area to the actual area of the patio is 0.1389 square feet : 320 square feet or 1 : 2306.56

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.
Answers
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).

Which expression is equal to the polynomial below 2x^4+5x^3-8x-20
Answers
The expression that is equal to the given Polynomial expression is (x^3-4)(2x+5).
The polynomial expression given is 2x^4+5x^3-8x-20. We have to identify the expression that is equal to this given polynomial expression.
We will factor the given polynomial expression to determine the equivalent expression. We can use factorization by grouping to factor the expression completely and determine the equivalent expression .
Factorization by grouping:
We can group the first two terms 2x^4 and 5x^3 together and factor out x^3 from them. We can also group the last two terms -8x and -20 together and factor out -4 from them.
This gives us;2x^4+5x^3-8x-20= x^3(2x+5)-4(2x+5) =(x^3-4)(2x+5)
Therefore, the expression that is equal to the given polynomial expression is (x^3-4)(2x+5).

with the two schools tied. Let x represent the number of correct answers given by School A in the final

Which equation models the scoring in the final round and the outcome of the contest?
OA. 9x + 2x - 62 = - 9x + 24
OB. 2x-9x + 62 = 9x + 24
OC. 9x - 2x - 62 = 9x + 24
OD. 9x - 2x + 62 = 9x + 24
Answers
Answer:
9x - 2x + 62 = 9x + 24
Number of correct answer each obtained = 19
Step-by-step explanation:
Given that:
Number of correct answers = x
POINTS for correct answers = 9
POINTS for incorrect answers = - 2
SCHOOL A:
Number of correct answers = x
Number of incorrect answers = x
Initial point = 62
Initial point + 9(number of correct answers) + - 2(number of incorrect answers)
62 + 9x - 2x
SCHOOL B :
Number of correct answers = x
Number of incorrect answers = 0
Initial point = 24
Initial point + 9(number of correct answers) + - 2(number of incorrect answers
24 + 9x
Since they end up tied :
School A = School B
62 + 9x - 2x = 24 + 9x
9x - 2x + 62 = 9x + 24
Number of correct answers gotten :
9x - 2x + 62 = 9x + 24
7x + 62 = 9x + 24
7x - 9x = 24 - 62
-2x = - 38
x = 19
Hence, Number of correct answers each obtained = 19

(Round your answer to one decimal place.) % Tries 0/99(2) How long does it take for his money to double? (Round your answer to two decimal places.) years Tries 0/99
Answers
We have to use the compount interest formula
\(\begin{gathered} A=P(1+r)^t \\ \frac{A}{P}=(1+r)^t \\ \\ \sqrt[t]{\frac{A}{P}}=\sqrt[t]{(1+r)^t}^ \\ \\ r=\sqrt[t]{\frac{A}{P}}\text{ - }1 \\ \\ r=\sqrt[21]{\frac{5000}{2000}}\text{ - }1 \\ r=0.04459 \\ r=4.45\%=4.5\% \end{gathered}\)A is the total amount
P is the principal amount
r is the interest annual rate, which is the unknown variable and t is the nnumber of yeaers
That would be the formula for the r. Let's find it then
For a the annual rate of interest is 4.5%
2) Now, we have the r, we can find the number 2 which is how long for it to double, so we have to find t.
\(\begin{gathered} A=P(1+r)^t \\ \\ 4000=2000(1+0.045)^t \\ \\ \frac{4000}{2000}=(1.045)^t \\ 2=1.045^t \\ \log_{1.045}2=t \\ \\ t=15.747=15.75\text{ years} \end{gathered}\)So, for it to double it takes 15.75 years.

The t-test value for the given collected data of hours of studying and exam grade is equal to 10.45.
As given in the question,

Mean of the exam grade μ₂ = ( 55 + 75 + 80 + 85 + 99) / 5

Standard deviation of time σ₁ = 1.82
Standard deviation of exam grade σ₂ = 16.04
Standard error of time = σ₁/√n

Standard error of time =σ₂/√n

Answers
You would expect to pay $90 each month for electricity based on an average usage of 120 KWHs per month.
How to find the expected monthly payTo calculate the monthly cost of electricity, you can multiply the average number of kilowatt-hours (KWH) used per month by the cost per KWH.
Given:
Cost per KWH: $0.75
Average monthly usage: 120 KWHs
To find the monthly cost, you can multiply the cost per KWH by the average monthly usage:
Monthly Cost = Cost per KWH * Average monthly usage
