Answer:

Graph B

Step-by-step explanation:

The equation for direct variation is y=kx, with k being the slope. As you can see from the equation, there is no y-intercept. In graph A, you would add 8; therefore, it does not meet the requirements for direct variation.

Answer:

Step-by-step explanation:

2. 2(3x+4)=10

6x+8=10

6x+8-8=10-8

6x=2

x= 1/3

3. 2x + 7 = 5x + 16

7 + 2x = 5x + 16

7 + 2x = 16 + 5x

7 + 2x + -5x = 16 + 5x + -5x

7 + -3x = 16 + 5x + -5x

7 + -3x = 16 + 0

7 + -3x = 16

7 + -7 + -3x = 16 + -7

0 + -3x = 16 + -7

-3x = 16 + -7

-3x = 9

x = -3

4. x/3-8=-2

x/3=6

x=18

5. 3x-6=-12

3x-6+6=-12+6

3x=-6

x=-2

sorry but i cannot solve 1 or 6 because i am quite stupid

What is the distance between ( 8 , − 3 ) (8,−3)left parenthesis, 8, comma, minus, 3, right parenthesis and ( 4 , − 7 ) (4,−7)lef

Elena L [17]

Given Information:

Point 1 = (8, −3)

Point 2 = (4, −7)

Required Information:

Distance between points = d = ?

Answer:

Distance between points = d = √32 = 5.657

Step-by-step explanation:

We are given two points,

(x₁, y₁) = (8, −3)

(x₂, y₂) = (4, −7)

We are asked to find the distance between these two points.

The distance is given by

$d = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2 }$

Substitute the given coordinates into above equation

$d = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2 } \\\\d = \sqrt{(4 - 8)^2 +(-7 - (-3))^2 } \\\\d = \sqrt{(-4)^2 +(-7 +3)^2 } \\\\d = \sqrt{(-4)^2 +(-4)^2 } \\\\d = \sqrt{16 +16 } \\\\d = \sqrt{32} \\\\d = 5.657$
