Answer:

Step-by-step explanation:

If there is a constant rate of change, its value will be ...

k = y/x

Please help In which table does y vary directly with x?

grigory [225]

Answer:

Table D

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Verify each case

Table A

For x=1, y=3

Find the value of k

$k=y/x$ -----> $k=3/1=3$

For x=2, y=9

Find the value of k

$k=y/x$ -----> $k=9/2=4.5$

the values of k are different

therefore

The table A not represent a direct variation

Table B

For x=1, y=-5

Find the value of k

$k=y/x$ -----> $k=-5/1=-5$

For x=2, y=5

Find the value of k

$k=y/x$ -----> $k=5/2=2.5$

the values of k are different

therefore

The table B not represent a direct variation

Table C

For x=1, y=-18

Find the value of k

$k=y/x$ -----> $k=-18/1=-18$

For x=2, y=-9

Find the value of k

$k=y/x$ -----> $k=-9/2=-4.5$

the values of k are different

therefore

The table A not represent a direct variation

Table D

For x=1, y=4

Find the value of k

$k=y/x$ -----> $k=4/1=4$

For x=2, y=8

Find the value of k

$k=y/x$ -----> $k=8/2=4$

For x=3, y=12

Find the value of k

$k=y/x$ -----> $k=12/3=4$

All the values of k are equal

therefore

The table D represent a direct variation or proportional relationship

The linear equation is $y=4x$

Answer:

3.162 units

Step-by-step explanation:

First identify the points that undergo transformation

You have;

A = (0,0) and B =(1,3)

The transformation is T: (x,y)= (x+2, y+1), this means to get the image you add the x coordinate of the object to 2, and the y coordinate to 1.

Finding coordinates of the image points A' and B'

A'= (0+2,0+1) = (2,1)

B'=(1+2, 3+1)=(3,4)

Finding the distance A'B'

The formula for distance d is

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

where

x₁=2

x₂=3

y₁=1

y₂=4

d=distance between two points

Applying the formula

$d=\sqrt{(3-2)^2+(4-1)^2} \\\\\\d=\sqrt{1^2+3^2} \\\\\\d=\sqrt{1+9} \\\\\\d=\sqrt{10} \\\\\\d=3.162$

The distance A'B' is √10 =3.162 units
