Answer:

23, 32, 69

Step-by-step explanation:

3 numbers x, y, z

z = 3x

y = x + 9

x+y+z=124

x + (x + 9) + 3x = 124

5x + 9 = 124

5x = 115

x = 23

y = 32

z = 69

check: 23 + 32 + 69 = 124

Which of the following options is a better purchase for a bicycle? Option 1: A cash sale for $88
stellarik [79]

<u><em>Answer:</em></u>

Option 3

<u><em>Explanation:</em></u>

<u>To get the value of the cheapest bike, best option, we will calculate the total cost of each bike:</u>

<u>i- Option 1:</u>

Total cost = $88

<u>ii- Option 2:</u>

$5 down payment and $8 per week for 10 weeks

Total cost = 5 + 8(10) = 5 + 80 = $85

<u>iii- Option 3:</u>

$12 down payment and $5 per month for 12 months

Total cost = 12 + 5(12) = 12 + 60 = $72

<u>iv- Option 4:</u>

$20 down payment and $20 per month for 12 months

Total cost = 20 + 20(12) = 20 + 240 = $260

<u>Now, from the above calculations, we can conclude that:</u>

The best price would be that of option 3 ($72). It is the lowest price compared to other option.

Hope this helps :)

Frequently on tour, a band called the Chieftains
JulijaS [17]

Correct option is C. Frequently on tour, a band called the Chieftains

<u>revered internationally</u><u> as spirited performers of </u><u>traditional Irish music</u><u>.</u>

<u />

<h3>What are Chieftains?</h3>

The Chieftains are a traditional Irish folk band formed in Dublin in 1962, by Paddy Moloney, Sean Potts and Michael Tubridy. Their sound, which is almost entirely instrumental and largely built around uilleann pipes, has become synonymous with traditional Irish music and they are regarded as having helped popularise Irish music around the world.

They have won six Grammys during their career and they were given a Lifetime Achievement Award at the prestigious BBC Radio 2 Folk Awards in 2002. Some music experts have credited The Chieftains with bringing traditional Irish music to a worldwide audience, so much so that the Irish government awarded them the honorary title of 'Ireland's Musical Ambassadors' in 1989.

I don’t get this one but the question was something about finding the equation.
Alina [70]

9514 1404 393

Answer:

  y = -(x -3)^2 +2

Step-by-step explanation:

The vertex form of the equation for a parabola is ...

  y = a(x -h)^2 +k

where the vertex is (h, k) and the value 'a' is a vertical scale factor.

The value of 'a' can be found by looking at the y-value of points ±1 either side of the vertex relative to the vertex. Here, the vertex y-value is +2 at x=3, and either side goes down 1 unit (to y=1) for 1 unit to the right or left. So, a = -1.

Using the values we've read from the graph for the vertex (h, k) = (3, 2) and the scale factor a = -1, we can write the equation as ...

  y = -(x -3)^2 +2
