What is the equation of the line in point-slope form containing the points (4, -1) and (10, 0)?

Answers

Find slope first
(0+1)/(10-4)= 1/6
Point slope: (y-y1) = m(x-x1)
Solution: (y+1) = 1/6(x-4)

Answer:

The equation of the line in point-slope will be:

[tex]y\:=\:\frac{1}{6}x-\frac{5}{3}[/tex]

Step-by-step explanation:

Given the points

(4, -1)(10, 0)

Finding the slope between  (4, -1) and (10, 0)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(4,\:-1\right),\:\left(x_2,\:y_2\right)=\left(10,\:0\right)[/tex]

[tex]m=\frac{0-\left(-1\right)}{10-4}[/tex]

[tex]m=\frac{1}{6}[/tex]

We know that the slope-intercept form of the line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

Using the slope-intercept form to find the y-intercept 'b'

[tex]y = mx+b[/tex]

substituting m = 1/6 and the point (4, -1)

[tex]-1\:=\:\frac{1}{6}\left(4\right)+b[/tex]

[tex]\frac{2}{3}+b=-1[/tex]

subtract 2/3 from both sides

[tex]\frac{2}{3}+b-\frac{2}{3}=-1-\frac{2}{3}[/tex]

[tex]b=-\frac{5}{3}[/tex]

now substituting b = -5/3 and m = 1/6 in the slope-intercept form

[tex]y = mx+b[/tex]

[tex]y\:=\:\frac{1}{6}x+\left(-\frac{5}{3}\right)[/tex]

[tex]y\:=\:\frac{1}{6}x-\frac{5}{3}[/tex]

Therefore, the equation of the line in point-slope will be:

[tex]y\:=\:\frac{1}{6}x-\frac{5}{3}[/tex]

Pedro has a student loan of $62,845. This loan has a simple interest rate of 7% per year. What is the amount of interest that Pedro will be charged on this loan at the end of the year?​

Answers

I believe it would be $4,399.15 because if you use the formula I=P*R*T
P=62,845
R=0.07 or 7%
T=1 year period
So overall your equation is 62845*0.07*1=$4,399.15
Now at this point the interest is added onto the principal amount to figure out some new amount after one year so:
62845.00+4399.15=$67,244.15

Jordan is another employee at the same coffee shop. He has worked there longer than Gabe and earns 3 more per hour than Gabe. How much money will he earn after the following hours: 4, 8 ,12 and 16

Answers

Answer:

1.

- Gabe earns 13.5 per hour

2.

x ------------------ 4  ---- 8 --------- 12 ------ 16

Earnings ----- 57 ---- 111 ------- 165------ 219

Step-by-step explanation:

See attachment for complete question

Solving (a): Gabe's earnings per hour,

To do this, we simply calculate the slope (m) of the table.

[tex]m = \frac{y_2 - y_1}{x_2- x_1}[/tex]

Where

[tex](x_1,y_1) = (3,40.5)[/tex]

[tex](x_2,y_2) = (6,81.0)[/tex]

[tex]m = \frac{y_2 - y_1}{x_2- x_1}[/tex]

[tex]m = \frac{81 - 40.5}{6 - 3}[/tex]

[tex]m = \frac{40.5}{3}[/tex]

[tex]m = 13.5[/tex]

Hence, Gabe earns 13.5 per hour

Solving (b): Jordan earnings

First, we calculate the equation of Gabe's table using:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = 13.5[/tex] and [tex](x_1,y_1) = (3,40.5)[/tex]

[tex]y - 40.5 = 13.5(x - 3)[/tex]

[tex]y - 40.5 = 13.5x - 40.5[/tex]

[tex]y = 13.5x[/tex]

If Jordan earns 3 more per hour than Gabe, then: Jordan's equation would be;

[tex]y = 13.5x + 3[/tex]

When x  = 4

[tex]y = 13.5*4 + 3 = 54 + 3 = 57[/tex]

When x = 8

[tex]y = 13.5*8 + 3 = 108 + 3 = 111[/tex]

When x = 12

[tex]y = 13.5*12 + 3 = 162 + 3 = 165[/tex]

When x = 16

[tex]y = 13.5*16 + 3 = 216 + 3 = 219[/tex]

About 9/10 Of the avocados grown in the United States are in California about what percent of our car is going in the United States are grown in California?

Answers

Answer:

9/10 x 100% = 90%

Step-by-step explanation:

The question is asking us to convert the given fraction, 9/10, to percentage. As we know, to convert any number to percentage, we simply multiple by 100%. We are not changing the value because 100% means 100/100 = 1. So, we are basically multiplying by 1.

Since we are told that 9/10 avocados grown in the US are grown in California, then the percentage would be:

9/10 x 100% = 90%

Answers

Answer:

y = ⅔x - 5

Step-by-step explanation:

To write the equation, find the slope (m), to enable you write the equation of the line in point-slope form given a point, (-3, -7) that the line passes through.

Since the line is parallel to 2x - 3y = 24,, it would have the same slope (m) value.

Rewrite 2x - 3y = 24 in slope-intercept form.

Thus:

2x - 3y = 24

-3y = -2x + 24

y = ⅔x - 12

The slope of 2x - 3y = 24 is ⅔. Therefore, the line that is parallel to 2x - 3y = 24 is also ⅔.

To write the equation of the line, substitute (a, b) = (-3, -7) and m = ⅔ into y - b = m(x - a)

Thus:

y - (-7) = ⅔(x - (-3))

y + 7 = ⅔(x + 3)

y + 7 = ⅔x + 2

y = ⅔x + 2 - 7

y = ⅔x - 5

A company which uses the revaluation model for its PPE bought a building on 1 January 2014 for £50m. The building has an estimated useful life of 50 years and nil residual value. On 31 December 2018, the building was revalued at £40.5m and on 31 December 2020 it was revalued for a second time at £39m. The company uses the straight-line method of depreciation for all PPE items. There was no change to the remaining useful life after each revaluation. What is the net effect of both revaluations on the statement of comprehensive income?

Answers

Answer:

The net effect of both revaluations on the statement of comprehensive income is a net revaluation loss of £4.20m that will reduce the comprehensive income by the exact amount of £4.20m.

Step-by-step explanation:

This can be determined using the following 3 steps:

Step 1: Calculation of the effect of first revaluation: from 01 January 2014 to 31 December 2018

Building cost = £50

Number of useful life = 50

Revalued amount on 31 December 2018 = £40.5m

Annual depreciation expenses from 01 January 2014 to 31 December 2018 = Building cost / Number of useful life = £50m / 50 = £1m

Number of years from 01 January 2014 to 31 December 2018 = 5

Total depreciation expenses from 01 January 2014 to 31 December 2018 = Annual depreciation expenses from 01 January 2014 to 31 December 2018 * Number of years from 01 January 2014 to 31 December 2018 = £1m * 5 = £5m

Net book value on 31 December 2018 = Building cost - Total depreciation expenses from 01 January 2014 to 31 December 2018 = £50m - £5m = £45m

Revaluation loss from the first revaluation = Net book value on 31 December 2018 - Revalued amount on 31 December 2018 = £45m - £40.5m = £4.50m

Step 2: Calculation of the effect of second revaluation: from 01 January 2019 to 31 December 2020

Revalued amount on 31 December 2020 = £39m

Number of useful life remaining after 31 December 2018 = Number of useful life - Number of years from 01 January 2014 to 31 December 2018 = 50 - 5 = 45

Annual depreciation expenses from 01 January 2019 to 31 December 2020 = Revalued amount on 31 December 2018 / Number of useful life remaining after 31 December 2018 = £40.5m / 5 = £0.90

Number of years from 01 January 2019 to 31 December 2020 = 2

Total depreciation expenses from 01 January 2019 to 31 December 2020 = Annual depreciation expenses from 01 January 2019 to 31 December 2020 * Number of years from 01 January 2019 to 31 December 2020 = £0.90 * 2 = £1.80

Net book value on 31 December 2020 = Revalued amount on 31 December 2018 - Total depreciation expenses from 01 January 2019 to 31 December 2020 = £40.5m - £1.80 = £38.70m

Revaluation surplus from the second revaluation = Revalued amount on 31 December 2020 – Net book value on 31 December 2020 = £39m - £38.70 = £0.30m

Step 3: Calculation of the net effect of both revaluations on the statement of comprehensive income

Net revaluation loss = Revaluation loss from the first revaluation - Revaluation surplus from the second revaluation = £4.50m - £0.30m = £4.20m

Therefore, the net effect of both revaluations on the statement of comprehensive income is a net revaluation loss of £4.20m that will reduce the comprehensive income by the exact amount of £4.20m.

The net effect of the revaluations on December 31, 2018 and December 31, 2020 is that the comprehensive income will reduce by £11 million.

Data and Calculations:

Cost of PPE on January 1, 2014 = £50 million

December 31, 2018:

Revaluation amount =                   £40.5 million

Revaluation Loss =                          £9.5 million (£50 million - £40.5 million)

New book value =                        £40.5 million

December 31, 2020:

Revaluation amount =                   £39 million

Revaluation Loss =                          £1.5 million (£40.5 million - £39 million)

New book value =                        £39 million

Total Revaluation Loss = £11 million (£9.5 + £1.5 million)

Thus, the net effect of both revaluations on the company's statement of comprehensive income is reduction of £11 million.
