What is an equation of the line that passes through (0, 4) and (2,8)?

Answers

Answer 1

Answer:

y=2x+4

Step-by-step explanation:

Hi there!

We are given the points (0, 4) and (2,8)

We want to write the equation of the line that passes through these two points

There are 3 ways to write the equation of the line, but the most common way is with slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

So, to use this way, we need to find the slope of the line

The slope can be calculated using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We are already given the points needed to find the slope, but let's label them to avoid any confusion

[tex]x_1=0\\y_1=4\\x_2=2\\y_2=8[/tex]

Now substitute these values into the formula.

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{8-4}{2-0}[/tex]

Subtract

m=[tex]\frac{4}{2}[/tex]

Divide

m=2

The slope of the line is 2

Here is the equation of the line so far:

y=2x+b

Now we need to find b

As stated before, b is the y intercept of the line, which is the point in where the line passes through the y axis; the value of x at this point is 0

One of the points we were given earlier is actually the y intercept of the line; that point is (0, 4) *notice how x=0 at this point

The value of b is the value of y at the y intercept; in this case, the value of b is 4

Substitute 4 as b into the equation

y=2x+4

Hope this helps!

Answers

Answer:

Step-by-step explanation:

1.1 L

Given:

A rectangular container that has:

   a length of 30 cm,

   a width of 20 cm, and

   a height of 24 cm

It is filled with water to a depth of 15 cm.

When an additional 6.5 L of water are poured into the container, some water overflows.

Question:

How many liters of water overflow the container?

The Process:

Step-1: calculate the volume of rectangular container

The volume of rectangular container is 14,400 cm³, then converted to 14,4 L.

Step-2: calculate the volume of water filled in the container to a depth of 15 cm

The volume of water filled is 9,000³ cm, then converted to 9 L.

Step-3: calculate the volume of water overflow when an additional 6.5 L of water is poured into a container.

The volume of water overflow equals the initial water volume is added to the additional water volume then subtracted by the container volume.

The volume of water overflow =

Thus, the volume of water overflow of the container is 1.1 L.

What is tax?

A tax is some specific financial amount or some other charged taxpayer by the government in order to fund government spending.

Given is that you have to buy a new computer for $800.00 or a refurbished computer with the same equipment for $640.00. If you are paid $10.00/hour and your deductions are -

FICA (7.65%),

Federal tax withholding (12%)

State tax withholding (8%).

Total money earned after all the deductions -

A{n} = 10 - {7.65% of 10 + 12% of 10 + 8% of 10}

A{n} = 10 - {7.65/100 x 10 + 12/100 x 10 + 8/100 x 10}

A{n} = 10 - {7.65/10 + 12/10 + 8/10}

A{n} = 10 - 2.765

An = 7.235

Cost of new computer = $800.

For 1 hour. you earned $7.235.

Then, you will earn $1 in (1/7.235) hours

So, you will earn $800 in (1/7.235 x 800) = 110.5

Therefore, you will have to work 110.5 hours to buy the new computer.

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 8. If there were 6600 no votes, what was the total number of votes?

Answers

Answer:

The total number of voters = 10725

Step-by-step explanation:

The total number of votes cast was 5 + 8

The no votes ratio is 8/ 13

This question is a a proportion question.

A proportion question is 2 ratios equal to other. Three of the parts of the ratios are known and you are asked to find the fourth. In this question the no votes are known to be 8 and the total is 13.

The total no votes = 6600. So the three parts are known are

no vote ratio = 8No vote number =6600total vote ratio part = 13You are asked to find the total number of voters.

8/13 = 6600/x               Cross multiply

8x = 13*6600                Combine the right.

8x = 85800                   Divide by 8

8x/8 = 85800/8            

x = 10725

The total number of voters = 10725

Kevin uses 36 ounces of dried apples and 18 ounces of
dried cranberries to make a fruit snack. He plans to sell the snack in 1\2
containers. How may containers will he fill? Will any fruit snack be left over?

Answers

Answer:

6 containers

6 ounces of fruit snack will be left over

Step-by-step explanation:

1 pound = 16 ounces

⇒ ¹/₂ pound = 8 ounces

Total weight = weight of dried apples + weight of dried cranberries

                     = 36 + 18

                     = 54 ounces

Containers needed = total weight ÷ weight of snacks in one container

                                 = 54 ÷ 8

                                 = 6.75

Therefore, he will fill 6 containers

Snack left over = total weight - (number of containers × weight of snacks one container will hold)

                          = 54 - (6 × 8)

                          = 54 - 48

                          = 6 ounces

By using Euler's notation, we will see that:

z^7 = 78,125*e^(-i*4.48)

How to get z^7?

We know that:

z = 4 - 3i

Remember that for a complex number:

w = a + bi

In Euler's notation, we can write this as:

w = √(a^2 + b^2)*e^(i*Atan(b/a))

Then, for z, we will get:

z =  √(4^2 + (-3)^2)*e^(i*Atan(-3/4))

z = 5*e^(-i*0.64)

Now, if we apply an exponent of 7 to this number, we will get:

z^7 = ( 5*e^(-i*0.64))^7

z^7 = 5^7*e^(-i*7*0.64) = 78,125*e^(-i*4.48)

6.1291 < 8.3 < 8.308 < 8.38

Step-by-step explanation:

Start by looking at the whole numbers.

6 < 8


Since the only whole numbers are 6 and 8, we can rule out that the smallest number, or with the least value, is 6.

Next, look at the tens place.

Since they are all 8.3--, we cannot find the next one until we look at the hundredths place.

Next, look at the hundredths place.

Keep in mind that 8.3 is the same as 8.300

There is 8.30 < 8.38 and 8.308 <8.380

Now we know the lowest value and the highest value! (6.1291 and 8.38)

Between the last two, let's figure out where they place


Look at the thousandths place.

8.300 < 8.308

If point P partitions the segment MN in a 5 : 2 ratio, then to calculate the x and y values of point P:

divide the difference of the x (or y) values of the two endpoints by the sum of the ratiosmultiply this by 5, since P partitions the segment at 5 : 2add this to the x (or y) value of point M

x-value of P:

[tex]\sf \implies \left(\dfrac{x_N-x_M}{5+2}\right)\cdot5+x_N[/tex]
