Ux is a median of triangle UVW and XV = 4.6, find VW.

Write an equation in standard form for the line that passes through the given points.

Agata [3.3K]

So, pretend this is your x-axis and y-axis:

I

(-2,7) • I

I

I • (2, 5)

I

_________________I____________________

I

TO GET FROM POINT (-2, 7) TO POINT (2, 5), WE MOVE DOWN 2 AND OVER 4, SO THE SLOPE IS -1/2. IF WE FOLLOW THAT SLOPE AND MOVE DOWN 1 AND OVER 2 FROM THE FIRST POINT OF (-2, 7), WE WILL LAND ON A POINT LOCATED AT (0, 6), WHICH WOULD BE THE "Y-INTERCEPT". WE WERE JUST ABLE TO CALCULATE THE SLOPE OF THE LINE AND THEN USE THE SLOPE TO FIND THE INTERCEPT. SO, THE "SLOPE-INTERCEPT" FORM OF THE EQUATION FOR THIS LINE IS:

y = -1/2x + 6

TO RE-WRITE THIS IN STANDARD FORM, WE JUST WANT TO MOVE THE X VARIABLE OVER TO THE LEFT WITH THE Y VARIABLE, SO:

y = -1/2x + 6

+1/2x + 1/2x

1/2x + y = 6 .... and that is your answer!

Which relationships have the same constant of proportionality between yyy and xxx as the equation 3y=27x3y=27x3, y, equals, 27,

Tanya [424]

Answer:

A, B and C

Step-by-step explanation:

In the equation: 3y=27x

Making y the subject of the equation, we have:

$y=\frac{27}{3}x\\y=9x$

The constant of proportionality between y and x is 9.

We want to determine which relationships have the same constant of proportionality 9.

Option A

y=9x

The constant of proportionality is 9.

Option B

2y=18x

Divide both sides by 2 to obtain: y=9x

The constant of proportionality is 9.

Option C

x=3, y=1/3

Substitution into y=kx gives:

1/3=3k

k=9

The constant of proportionality is 9.

Option D

x=6, y=2/3

Substitution into y=kx gives:

2/3=6k

k=2/3*6=4

The constant of proportionality is 4.

Option E

When x=2, y=18

Substitution into y=kx gives:

18=2k

k=9

However, when x=4, y=27

Substitution into y=kx gives:

27=4k

k=6.75

This is not a proportional relation since the constant of proportionality is not equal.

The correct options are A, B and C

A website had 826, 140 hits last month what is the value of the 8 in 826,140

Angelina_Jolie [31]

800,000 or eight hundred thousand.

<h3>Further explanation</h3>

Problem: The given number is 826,140.

Question: What is the value of the digit 8?

The Process:

This is a problem with place value.

Let us set the place values from 826,140 consecutively as follows.

In the thousands period: 8 hundred thousands, 2 ten thousands, 6 one thousands.
In the units period: 1 hundreds 4 tens 0 ones.

Let us say in word form: eight hundred twenty-six thousand six hundred forty.

Hence, the value of the 8 in the numbers 826,140 is 800,000 or eight hundred thousand.

- - - - - - -

Extra:

What is the value of the digit 6 in the numbers 826,140? The answer is 6,000 or six thousand.

- - - - - - -

Notes:

Recall that the digits in large numbers are in groups of three places, i.e.,

hundreds,
tens, and
ones (or units).

The groups are called periods, i.e.,

millions period
thousands period
ones or units period

Commas are typically used to separate the periods.

Answer:

upper left: -7/3, lower: 3, upper right: -2/3

Step-by-step explanation:

upper left :

(1-8)/(7-4)=-7/3

lower:

(9-0)/(4-1)=9/3=3

upper right:
