Answer:

(-11)

Step-by-step explanation:

The line joining the midpoint of two sides of the triangle, is parallel to the third side and half of the third side.

(1/2)VT = DC

(x + 17)* \dfrac{1}{2}=(2x + 25)

Multiply the whole equation by 2

x + 17 = 2*(2x + 25)

x + 17 = 4x + 50

17 - 50 + x = 4x

    -33 + x = 4x

- 33 = 4x - x

-33 = 3x

x = -33/3

x = -11

Tìm hai số có tổng là 177. Nếu bớt số thứ nhất đi 17 đơn vị và thêm vào số thứ hai 25 đơn vị thì số thứ nhất bằng 2/3 số thứ 2
Ira Lisetskai [31]

Trả lời:

86 và 91

Giải thích từng bước:

Cho hai số là x và y. Nếu tổng của chúng là 177, thì;

x + y = 177 ... 1

Nếu 17 bị trừ đi số đầu tiên, nó được biểu thị là x - 17

Nếu 25 được thêm vào số thứ hai l, nó được biểu thị bằng y + 25

Nếu số thứ nhất bây giờ bằng 2/3 số thứ hai, thì:

x-17 = 2/3 (y + 25) .... 2

Từ 1, x = 177-y ... 3

Thay thế 3 thành 2

177-y-17 = 2/3 (y + 25)

160-y = 2/3 (y + 25)

3 (160-y) = 2 (y + 25)

480-3y = 2y + 50

-3y-2y = 50-480

-5y = -430

y = 430/5

y = 86

Vì x = 177-y

x = 177-86

x = 91

Do đó hai số là 86 và 91

If the data point is at (3, 10.5) and the prediction equation is y = -6.1x + 12.5, what is the value of the residual for this da
Keith_Richards [23]

Given:

The data point is (3,10.5).

The prediction equation is y=-6.1x+12.5.

To find:

The value of the residual for this data point.

Step-by-step explanation:

The data point is (3,10.5). So, the actual value is 10.5 at x=3.

Prediction equation is

y=-6.1x+12.5

Putting x=3, we get

y=-6.1(3)+12.5

y=-18.3+12.5

y=-5.8

The formula for residual is:

Residual = Actual value - Expected value

Residual=10.5-(-5.8)

Residual=10.5+5.8

Residual=16.3

Therefore, the residual for the given data point is 16.3.

An airplane flying at attitude of 32,000 feet descends at a rate of 1,300 feet per minute. If the plane descends for 15 minutes,
Furkat [3]
Since the plane descends 1,300 feet per minute it would descend 19,500 feet after 15 minutes (1,300 x 15 = 19,500) Subtract this from the plane's initial altitude 32,000 and the new altitude will be 12,500. (32,000-19,500=12,500)

Option 1: $30 an hour plus a non-refundable deposit of $50. Option 2: $20 an hour plus a non-refundable deposit of $75. Kyle is
Margaret [11]
Option 1 equation- 30x+50
Option 2 equation- 20x+75
There is automatically a one time fee of $50 for option 1 and $75 for option 2

1 day:
Option 1- this person pays a total of $80 (because of the one time fee of 50 and 30 per day)
option 2- pays a total of $95 (one time fee of 75 and then an additional 20 per day)

Day 2:
Option 1- $80+$30(daily fee)=$110
Option 2- $95+$20(daily fee)=$115

Day 3:
Option 1- $110+$30=$140
Option 2-$115+$20=$135

They will have to stay a minimum of 3 days for option 2 to be a better deal
