dangina [55]

Answer:

m = undef

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

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

Step-by-step explanation:

Step 1: Define

Point (3, -2)

Point (3, 6)

Step 2: Find slope m

Substitute: $m=\frac{6+2}{3-3}$
Add/Subtract: $m=\frac{8}{0}$
Divide: m = undef

When we divide anything by zero, we will get undefined. Therefore, this would be a vertical line.

What is 1735/1000 written as a decimal?

Marat540 [252]

Answer:

$\frac{1735}{1000}$ as a decimal is 1.735.

Step-by-step explanation:

To convert a fraction into a decimal, you first have to put the fraction into simplest form.

1. Simplest form

$\frac{1735}{1000} = \frac{347}{200}\\\$

To do this you must find a number you can equally divide both numbers by.

That number in this situation, 5.

$1000/5= 200\\1735/5= 347\\1735:1000 = 347:200\\\frac{1735}{1000} =\frac{347}{200}$

Now you must make this simplest formed fraction into a mixed number.

2. Simplest form into Mixed number

$\frac{347}{200}= 1\frac{147}{200}$

To do this you see how many times the denominator, the bottom number of the fraction, goes into the numerator, the upper part of the fraction.

Since 200 x 2 = 400 and since 400 > 347 this means...

200 goes into 347, once.

Finally, subtract and divide.

Remember put the whole number in front of the mixed number, before the decimal

3. Subtract, divide, decimalize

$147/200= 0.735\\\\1\frac{147}{200}= 1.735$

Hopes this helps you!

Have a good afternoon!

Half the marbles in a bag are red, 1/6 of the marbles are blue, and the remaining 8 marbles are white how many total marbles are

Gemiola [76]

Hey there! I'm happy to help!

Let's represent the total number of marbles with the variable t. We have the following information.

1/2t+1/6t+8=t (1/2 of total are red, 1/6 of total are blue, 8 are white, add them up to get total)

Now, we solve for t.

1/2t+1/6t+8=t

We combine like terms.

2/3t+8=t

We subtract t from both sides.

-1/3t+8=0

We subtract 8 from both sides.

-1/3t=-8

We divide both sides by -1/3.

t=24

Therefore, there ae 24 total marbles in the bag.

Have a wonderful day! :D

Connecting a DVD player to a television set requires a cable with special connectors at both ends. You buy a six-foot cable for

ankoles [38]

So a 3 foot cable is10.25
a 6foot cable is 15.50
so
x=cost per foot
y=cost of special connectors
3x+y=10.25
6x+y=15.50
make first equation negative and add to the first
3x=5.25
divide both sides by 3
1.75=x
so it costs 1.75 for a foot of cable

subtitue into first equation
3(1.75)+y=10.25
5.25+y=10.25
subtract 5.25 from both sides
y=5 dollars=cost of special so
4x+y=4(1.75)+5=7+5=$12

so the cost of a 4 foot cable is $12
