What is the equation of the line through (5,1) with a slope of -3?

PilotLPTM [1.2K]

Answer:

C

Step-by-step explanation:

The equation of a line is given by the formula $y-y_1=m(x-x_1)$

Where $x_1$ is the x-coordinate (it is given as 5)

$y_1$ is the y-coordinate (it is given as 1), and

m is the slope (it is given as -3)

Plugging in all the info into the formula we have:

$y-y_1=m(x-x_1)\\y-1=-3(x-5)$

From the answer choices, we see that C is the correct answer.

How in the world do I answer this problem??

galben [10]

Answer:

22

Step-by-step explanation:

ST is y and SU is 2y-4.

Note that SU = ST + TU = y + 18

So we have 2y - 4 = y + 18

2y - 4 = y + 18

2y = y + 22

y = 22

So ST is 22.

A random sample of 23 items is drawn from a population whose standard deviation is unknown. The sample mean isx⎯ ⎯ x¯ = 840 and

gayaneshka [121]

Answer:

$(832.156, \ 847.844)$

Step-by-step explanation:

Given data :

Sample standard deviation, s = 15

Sample mean, $\overline x = 840$

n = 23

a). 98% confidence interval

$\overline x \pm t_{(n-1, \alpha /2)}. \frac{s}{\sqrt{n}}$

$$E= t_{( n-1, \alpha/2 )} \frac{s}{\sqrt n}}$

$t_{(n-1 , \alpha/2)} \frac{s}{\sqrt n}$

$t_{(n-1, a\pha/2)}=t_{(22,0.01)} = 2.508$

∴ $E = 2.508 \times \frac{15}{\sqrt{23}}$

$E = 7.844$

So, 98% CI is

$(\overline x - E, \overline x + E)$

$(840-7.844 , \ 840+7.844)$

$(832.156, \ 847.844)$

Calculate the taxes based on the following taxable income amounts

Bingel [31]

1.) Taxable income is 22,764.42 (income 90,714 less range which is more than 87,850 but less than 183,250 = 2,864 multiply to its corresponding tax rate of 28% = 801.92 plus its corresponding amount of 21,962.50 = 22,764.42)

2.) Taxable income is 12,140.75

3.) Taxable income is 63,634.18

4.) Taxable income is 44,097.62

5.) Taxable income is 63,691.60

6.) Taxable income is 24,598.98

7.) Taxable income is 59,234.62

8.) Taxable income is 171,662.58

9.) Taxable income is 184,033.22

10.) Taxable income is 183,997.18

11.) Taxable income is 61,067.11

12.) Taxable income is 153,877.82

13.) Taxable income is 241,356.99

14.) Taxable income is <span>274,376.26
</span>
15.) Taxable income is 97,208.05

Note: Use the "from" amount as the basis, so if the income is 10,000 then you'll deduct 8,925 (basis) from 10,000 (since 10,000 is more than 8,925 but less than 36,250)
