Answer:
Ax + By = C is standard form.
Step-by-step explanation:
It is standard form because slope intercept is y = mx + b and point slope is y-y₁=m(x-x₁)
Hope this helps
Answer:
Standard form.
Step-by-step explanation:
y=mx + b is the slope-intercept form.
The y-intercept of the function f(x) = :
2/3[x| + 4 is (0,4). If the
function is translated down 9 units, what will be the new y-intercept?
The new y-intercept of the function is (0. -5)
How to determine the new y-intercept?From the question, we have the following parameters that can be used in our computation:
f(x) = 2/3|x + 4}
y-intercept = (0. 4)
The function is translated by
9 units down
This is represented as
(x, y) = (x, y - 9)
Substitute the known values in the above equation, so, we have the following representation
New y-intercept = (0. 4 - 9)
Evaluate
New y-intercept = (0. -5)
Hence, the new y-intercept = (0. -5)

If you can make payments of $450 on a 5-year loan that has an APR of 6.5%,
what is the maximum loan amount you can afford?
Answer:
To determine the maximum loan amount you can afford, you need to know the amount of your monthly payment and the annual percentage rate (APR) of the loan. The APR is the interest rate of the loan, expressed as a yearly rate. It takes into account not only the interest rate, but also any fees or other charges associated with the loan.
In this case, you know that you can make monthly payments of $450 and that the APR of the loan is 6.5%. To determine the maximum loan amount you can afford, you can use the following formula:
Maximum loan amount = (Monthly payment / (APR / 100 / 12)) * (1 - (1 + (APR / 100 / 12))^-n)
where n is the number of monthly payments. In this case, you are taking out a 5-year loan, which means you will make 60 monthly payments (5 years * 12 months/year = 60 months), so n = 60. Plugging these values into the formula, we have
Maximum loan amount = ($450 / (6.5% / 100 / 12)) * (1 - (1 + (6.5% / 100 / 12))^-60)
= ($450 / 0.00542) * (1 - (1 + 0.00542)^-60)
= $83,146.54
Therefore, the maximum loan amount you can afford is $83,146.54. This is the maximum amount you can borrow, assuming that you make monthly payments of $450 and the APR of the loan is 6.5%. You should carefully consider your ability to make these monthly payments before taking out a loan of this amount.

1. The translation was of 4 units right and 3 units down.
2. All the blue lines connecting the equivalent vertices will have a slope of -3/4.
What is the translation?
The translations of the triangle is given by the rule presented as follows:
(x,y) -> (x + 4, y - 3).
Hence the meaning of each of these translations is given as follows:
x -> x + 4 is a translation of four units right.y -> y - 3 is a translation of three units down.The coordinates of the original vertices are given as follows:
(0,0), (0,4), (3,0).
Then the coordinates of the translated vertices are given as follows:
(4,-3), (4,1), (7,-3).
For a linear function, the slope is given by the vertical change divided by the horizontal change.
From these translations, the changes are given as follows:
Vertical change of 3 units down, hence of -3.Horizontal change of 4 units right, hence of +4.Thus the slope of the linear function connecting the original vertices are given as follows:
m = -3/4.

At one point the average price of regular unleaded gasoline was $3.65 per gallon. Assume that the standard deviation price per gallon is $0.06 per gallon and use Chebyshev's inequality to answer the following.
(a) What percentage of gasoline stations had prices within 4 standard deviations of the mean?
(b) What percentage of gasoline stations had prices within 1.5 standard deviations of the mean? What are the gasoline prices that are within 1.5 standard deviations of the mean?
(c) What is the minimum percentage of gasoline stations that had prices between $ 3.43 and $3.83 ?
Prices at 93.75% of gasoline stations were within four standard deviations of the mean. Prices at 44.44% of gas stations were within 1.5 standard deviations of the mean. The prices within 1.5 standard deviations of the mean are $3.56 to $3.74. The minimum percentage of gasoline stations with prices between $3.43 and $3.83 is 15.46%.
Chebyshev's inequality states that the proportion of data within k standard deviations of the mean is at least 1 - 1/k² for all values of k.
(a) To find the percentage of gasoline stations with prices within 4 standard deviations of the mean, we can plug k = 4 into the formula above to get 1 - 1/4² = 1 - 1/16 = 15/16 = 93.75%.
(b) To find the percentage of gasoline stations with prices within 1.5 standard deviations of the mean, we can plug k = 1.5 into the formula above to get 1 - 1/1.5² = 1 - 1/2.25 = 4/9 = 44.44%. The prices within 1.5 standard deviations of the mean are $3.65 +/- (1.5 × 0.06) = $3.65 +/- $0.09, so the prices within 1.5 standard deviations of the mean are $3.56 to $3.74.
(c) To find the minimum percentage of gasoline stations with prices between $3.43 and $3.83, we can use Chebyshev's inequality with k = ($3.83 - $3.43)/(0.06) = 4.17. Plugging this value into the formula gives us 1 - 1/k² = 1 - 1/17.3 = 15.46%, which is the minimum percentage of gasoline stations with prices between $3.43 and $3.83.

The angle measurement of T is 80°.
What is an angle measurement?When two lines or rays intersect at a common point, an angle is formed. The common point is referred to as the vertex. An angle measure in geometry is the measurement of the angle formed by two rays or arms at a common vertex.Here given,
∠Q = (9x - 17)°
∠R = (4x + 28)°
Since ∠Q and ∠R are co-interior angles in parallel lines.
∠Q + ∠R = 180°
So,
(9x - 17) + (4x + 28) = 180°
= 9x - 17 + 4x + 28 = 180°
By adding x variables together,
13x + 11 = 180°
=> 13x = 180°-11
=> x = 169° ÷ 13
x = 13
By substituting x,
∠Q = 9 x 13 - 17
= 117 - 17
= 100°
∠Q + ∠T = 180° (angles on a straight line is 180°)
100 + ∠T = 180°
∠T = 180 - 100
∠T = 80°
Therefore the value of ∠T is 80°.

select the most appropriate response. in the construction of confidence intervals, if all other quantities are unchanged, a decrease in the sample size will lead to a interval.
If all other quantities are unchanged, a decrease in the sample size will lead to a wider confidence interval.
What is a sample size?
Sample size refers to the number of observations or measurements that are taken from a larger population as part of a statistical study. In statistical analysis, a sample is a subset of the population being studied, and the sample size is the number of observations or units of analysis included in the sample.
A decrease in the sample size will lead to a wider confidence interval in the construction of confidence intervals.
In statistical inference, a confidence interval is a range of values that is estimated to contain the true value of a population parameter with a certain level of confidence. The width of the confidence interval depends on several factors, including the sample size, the level of confidence, and the variability of the data.
In general, as the sample size increases, the precision of the estimate of the population parameter improves, and the width of the confidence interval decreases. Conversely, as the sample size decreases, the precision of the estimate decreases, and the width of the confidence interval increases.
Hence, if all other quantities are unchanged, a decrease in the sample size will lead to a wider confidence interval.

value at the end of 3rd year will be Rs.
If it is sold for Rs.45000, the firm will make
profit/loss of Rs.
Answer:
The profit or loss on selling a fixed asset will be
Step-by-step explanation:
We know that,
Depreciation = Original value - Scrap value / Estimated life of an asset
-> 100,000 - 0/ 5
= Rs 20,000 for every year
for 3 years,
Depreciation= 3 * 20,000 = Rs 60,000
The value of the asset after 3 years of depreciation = 100,000- 60,000
=Rs 40,000 ---(1)
If it is sold for Rs 45,000 ---(2)
Profit = (2) - (1)
= 45,000-40000
= Rs 5,000
