Distance = √(x2-x1)² + (y2-y1)²
= √(2+1)² + (8-9)²
= √3² + (-1²)
=  √ 3+1
= √4
= 2

In short, Your Answer would be 2 units

Hope this helps!

Answer:

The distance is equal to 3.16

Step-by-step explanation:

To find the distance between the points (2, 8) and (-1, 9), we will follow the steps below;

First we need to write down the formula for finding distance between two points.

D = √(x₂ - x₁)² + (y₂ - y₁)²

From the question, the points given are;   (2, 8) and (-1, 9)

This implies that;  x₁ = 2      y₁ = 8        x₂=-1        y₂ = 9

We can now proceed to insert our values into the formula;

D = √(x₂ - x₁)² + (y₂ - y₁)²

D = √(-1 - 2)² + (9 - 8)²

D = √(-3)² + (1)²

D = √9 + 1

D = √10

D =3.16

The distance is equal to 3.16

FIND THE VALUEOF THE VARIBLE AND FILL THE BLANK.

Answer:

f = 2

g = 8

h = -9

k = 40

m = 1

Step-by-step explanation:

Equation 1:

23f - 17 = 29

Add 17 to both sides. This undoes the -17.

23f = 29 + 17

Add 17 to 29 to get 46.

23f = 46

Divide both sides by 23. This undoes the multiplication by 23.

f = 46/23

Divide 46 by 23 to get 2.

f = 2

Equation 2:

2(3g + 4) = 56

Divide both sides by 2. This undoes the multiplication by 2.

3g + 4 = 56/2

Divide 56 by 2 to get 28.

3g + 4 = 28

Subtract 4 from both sides. This undoes the +4.

3g = 28 - 4

Subtract 4 from 28 to get 24.

3g = 24

Divide both sides by 3. This undoes the multiplication by 3.

g = 24/3

Divide 24 by 3 to get 8.

g = 8

Equation 3:

h + 9 = 0

Subtract 9 from both sides. This undoes the +9.

h = 0 - 9

Any number subtracted from 0 gives its negation.

h = -9

Equation 4

3(k - 8) = 96

Divide both sides by 3. This undoes the multiplication by 3.

k - 8 = 96/3

Divide 96 by 3 to get 32.

k - 8 = 32

Add 8 to both sides. This undoes the -8.

k = 32 + 8

Add 8 to 32 to get 40.

k = 40

Equation 5:

5m - 5 = 0

Add 5 to both sides. This undoes the -5

5m = 0 + 5

Anything plus 0 gives itself.

5m = 5

Divide both sides by 5. This undoes the multiplication by 5

m = 5/5

Anything divided by itself gives you 1.

m = 1
