Answer:

Step-by-step explanation:

It’s made up of the 1 dollar coin , .50 cents coin, .25 cents coin, and the .10 cents coin. If you multiply each by 25 you get the exact value , so these coins make it up but there is exactly 25 of each

The value of a bike depreciates by 55% per year. Work out the current value of a bike bought 2 years ago for £1300.

nikitadnepr [17]

Year 1: 1,300 * 55% = 715 depreciation
1,300 - 715 = 585 book value

Year 2: 585 * 55% = 321.75 depreciation
585 - 321.75 = 263.25 book value

Year 3: 263.25 * 55% = 144.79 depreciation
263.25 - 144.79 = 118.46 book value

If the bike was bought 2 years ago, then its current value is $263.25.

Currently, it is the beginning of Year 3 but depreciation is computed at the end of the year.

Determine if the two lines are parallel, perpendicular, or neither. Show the work used to get your answer

vichka [17]

Answer:

Perpendicular

Step-by-step explanation:

[1] We need to find the slopes of both lines! First, we will put them into standard form and then solve.

Standard form: y=mx+b

(1) 10x + 2y = 4

(subtract 10x from both sides)

2y = -10x + 4

(divide both sides by 2)

y = 5x+2

The slope is 5

(2) 5y - x = -5

(add x to both sides)

5y = x - 5

(divide both sides by 5)

y = $\frac{1}{5}$ x - 1

The slope is one-fifth

[2] Then, we need to determine if they are parallel, perpendicluar, or neither.

- If they are parallel they will have the same slope

- If they are perpendicular they will have exact opposite slopes

() Line 1 has a slope of 5 and line two has a slope of one-fifth. These are exact opposites so the lines are perpendicular.

(I hope this is correct and helped, have a nice day!)
