Answer:

A = (a+b)/2

G = sqrt(ab)

Step-by-step explanation:

To find the arithmetic mean, we add the numbers together, then divide by how many numbers

A = (a+b)/2

To find the geometric mean, we multiply the numbers and take the nth root

G = (ab) ^ 1/2

G = sqrt(ab)

Problem 3

Murljashka [212]

Answer:

$-\frac{2}{5}$

Step-by-step explanation:

Given expression:

2x + 5y = -10

The equation of a straight line is;

y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

Now;

let us write the given expression in slope intercept format;

2x + 5y = -10

5y = -2x - 10

y = $-\frac{2x}{5}$ - 2

So, the slope of the line is $-\frac{2}{5}$
