What is the distance from (−2, 4) to (0, −6)? round your answer to the nearest hundredth.
daser333 [38]
Formula for distance between two points:

d = √( (x₂ -x₁)² + (y₂ - y₁)²)

x₁ = -2, y₁ = 4, x₂ = 0,  y₂ = -6

d = √( (x₂ -x₁)² + (y₂ - y₁)²)

d = √( (0 -  -2)² + (-6 - 4)²)

d = √( (0 + 2)² + (-10)²)

d = √( (2)² + (-10)²)

d = √(4 + 100)

d = √104        Use a calculator

d  ≈ 10.1980

d ≈ 10.20 units    to the nearest hundredth.

Hi how can I graph this if it dosn't have a slope?<br> 1. y = (2/3)x - 1 <br> y = -x + 4
12345 [234]

System of Linear Equations entered :

[1] y - 2x/3 = -1

[2] y + x = 4

// To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 3

// Equations now take the shape:

[1] 3y - 2x = -3

[2] y + x = 4

Graphic Representation of the Equations :

-2x + 3y = -3 x + y = 4

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = -y + 4

// Plug this in for variable x in equation [1]

[1] 3y - 2•(-y +4) = -3

[1] 5y = 5

// Solve equation [1] for the variable y

[1] 5y = 5

[1] y = 1

// By now we know this much :

y = 1

x = -y+4

// Use the y value to solve for x

x = -(1)+4 = 3

I hope this help you

Karen has 9 feet of lace for her tablecloth. She used 3 feet of lace.
RideAnS [48]
First calculate th feet of lace she haven't used.
9 - 3 = 6 ft
now we can convert feet into yard. we can divide the amount into 3 because it says 3ft is 1yrd
6 / 3 = 2 yards
