Answer:

y = 6x direct variation

Step-by-step explanation:

Remember that direct variation is y = kx and inverse variation is y = k/x where k is a constant

x= 1 2 5 10

y= 6 12 30 60

First look at direct y = kx solving for k y/x =k

y/x from the table is 6/1 =6 12/2 = 6 30/5 =6 60/10 =6 so k=6

This is a direct variation with k=6

y = 6x

What numbers are 1.4 units from −3.2 on a number line? pick one from both sets of answers

Fantom [35]

First, add 1.4 to the number given.

-3.2 + 1.4 = 1.4 - 3.2 = -2.2

a.-2.2 is one of your answer

Next, subtract 1.4 to the number given

-3.2 - 1.4 = -4.6

a.-4.6 is your next answer

a. -2.2, a. -4.6 are your two answers

hope this helps

This table models a linear function. x −8 −4 4 8 y −3 0 6 9 Enter the coordinates of the y-intercept in the boxes.

adell [148]

Answer:

y-intercept is 3

Step-by-step explanation:

We are given table

x: -8 -4 4 8

y: -3 0 6 9

We can select any two points

$x_1=-8,y_1=-3$

$x_2=-4,y_2=0$

Firstly, we will find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{0+3}{-4+8}$

$m=\frac{3}{4}\quad$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

we can plug values

$y+3=\frac{3}{4}(x+8)$

now, we can solve for y

$y=\frac{3}{4}x+3$

For finding y-intercept , we can plug x=0

$y=\frac{3}{4}\times 0+3$

$y=0+3$

$y=3$

So,

y-intercept is 3

What is greater 66mm or 6cm

LuckyWell [14K]

66mm=6cm
So that means that any 66mm is 6cm point 6mm ===> 66cmm=6.6cm
Thus, 6cm is not greater but it is equal to 66mm
It's like you looking at 1yd=3feet which also means that 3feet=1yd.
