Answer: Y = 29

Step-by-step explanation:

We are given:

X = 7

Y = 8 + 3x

Since we know that the variable X is really the number 7, substitute it in...

Y = 8 + 3x

Y = 8 + 3(7)

Y = 8 + 21

Y = 29

Dovator [93]

Answer:

let t = no of minutes when they are at the same altitude

:

52200 - 3300t = 2500t

52200 = 3300t + 2500t

52200 = 5800t

t = 52200/5800

t = 9 minutes they will be at the same altitude

:

The altitude:

9*2500 = 22500 ft

:

Check on other train

52200 - 9(3300) =

52200 - 29700 = 22500 ft

Answer:

17

Step-by-step explanation:

To find a median, always order the numbers from least to greatest.

The numbers were:

15, 19, 9, 27, 21, 21, 10, 14

Arrange them:

9, 10, 14, 15, 19, 21, 21, 27

The middle number is always the median, but there are two middle numbers.

9, 10, 14, 15, 19, 21, 21, 27

15 and 19 are the two middle numbers

Add them together, and divide by 2.

15+19=34

34 ÷ 2= 17

∴The median is 17

aliya0001 [1]

Answer:

A: g(x)

Step-by-step explanation:

The equation is technically in vertex form "y = a(x – h)² + k", where the vertex is (h, k).

For the domain and range to be as stated in the problem, your "vertex" needs to be (2, 3), and so you want y = a(x – 2)² + 3 which is answer choice A
