Answer:

The answer is

N(a) = (a + 25) /4

Step-by-step explanation:

If the function is

A(n) = 4n -25

and we wish to get the inverse function N(a)

We let

A(n) = a

n = N(a)

Plugging in the values

a = 4 N(a) - 25

Arranging the equation:

4 N(a) = a + 25

N(a) = (a + 25) /4

A snake slithers 2/9 miles in 4/5 hours what is its speed in miles per hour
Mamont248 [21]

Answer:

5/18

Step-by-step explanation:

speed = distance / time

s = (2/9 miles) / (4/5 hours)

To divide by a fraction, multiply by the reciprocal:

s = (2/9) × (5/4)

s = 10/36

s = 5/18

So the snake's speed is 5/18 miles per hour.

The linear combination method gives a solution of (–4, 2) for which of these systems of linear equations?
Andrew [12]

Answer:

3x + 13y = 14

6x + 11y = -2

Step-by-step explanation:

<em>See Attachment for complete question</em>

To determine which of the options has (-4,2) as its solution; we have to test each linear combination until we arrive at an answer;

Given that

(x,y) = (-4,2)

Testing Option A

3x + 13y = 14

6x + 11y = -2

Substitute x = -4 and y = 2 in 3x + 13y = 14

3(-4) + 13(2) = 14

Open Brackets

-12 + 26 = 14

14 = 14

Substitute x = -4 and y = 2 in 6x + 11y = -2

6(-4) + 11(2) = -2

Open Brackets

-24 + 22 = 2

2 = 2

<em>In both cases, the expression on the right hand side equates to that on the left hand side; </em>

<em>Hence, there's no need to check for other options. </em>
