the distance between given points. (-4,1) and (0, 4)​

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)

Answer:

Rise is 4

Step-by-step explanation:

a) Flip the equation

4x - 2 = 2

b) Add 2 to both sides

4x - 2 + 2 = 2 + 2

4x = 4

c) Divide both sides by 4

4x/4 = 4/4

The area of a sidewalk that surrounds a rectangle of 4 ft by 6 ft  is 56 ft²

The given situation can be depicted in the attached picture.

Recall the formula to calculate the area of a rectangle:

  A = l ⨉ w

Where:

l = length

w = wide

In the attached picture, the area of the sidewalk is the one with green color.

Notice that:

Area of sidewalk = area of bigger rectangle – area of smaller rectangle

Parameters of the bigger rectangle:

l = 6 + 2 + 2 = 10 ft.

w = 4 + 2 + 2 = 8 ft.

Area of bigger rectangle = 10 x 8 = 80 ft²

Parameters of the smaller rectangle:

l = 6 ft.

w = 4 ft.

Area of bigger rectangle = 6 x 4 = 24 ft²

Hence,

Area of sidewalk = 80 - 24 = 56 ft²

The amount of the discount that was given is $300.

A discount reduces the price of an item. When a discount is given, the item becomes cheaper. VAT is value added tax. VAT increases the price of an item.

The equation that can be used to represent the total cost of the bicycle is:

Total cost after VAT and discount = (1 + VAT) x (marked price - discount)

1921 = (1 + 0.13) x (2,000 - d)

1921 = 1.13 x (2,000 - d)

In order to determine the value of discount, take the following steps:

Divide both sides of the above equation by 1.13

1921 / 1.13 = 2000 - d

1,700 = 2,000 - d

Combine similar terms: 2000 - 1700 = d

Add similar terms together: d = 300

B(4015) is the [tex]2008^{th[/tex]term of the sequence.

What is the sequence?

Since the mean of the first terms is, the sum of the first terms is n². Thus, the sum of the first 2007 terms is 2007² and the sum of the first 2008 terms is 2008² Hence, the 2008th term of the sequence is

2008² - 2007² = (2008 + 2007) (2008 - 2007) = 4015

Note that n² is the sum of the first n odd integers.

From inspection, we see that the sum of the sequence is n². We also notice that n² is the sum of the first n odd integers.

Because 4015 is the only odd integer, B is the answer.

Answer:

Okay so a couple key points

$5.00 to ship it

Postcard stamps = $0.34

First class stamps= $0.49

And lastly he has 7 first class stamps

So with that being said you take .49 and times it by 7 since he has seven of them and that would be $3.43

And now you take $3.49 and subtract it from the $5.00 you'd be left with $1.57

Now you take $.34 and divide it by $1.57 and you would get a total of 4.61 so that means you would need five postcard stamps

So to be able to ship the package you'd need 7 first class stamps and 5 postcard stamps

Using scientific notation, the first step in simplifying the expression is given by:

a. Addition and subtraction requires the terms to be "like terms" with the same power of the base 10, so you would need to change the second number to (0.026 x 10^5).

A number in scientific notation is given by:

[tex]a \times 10^b[/tex]

With the base being [tex]a \in [1, 10)[/tex].

For two numbers in scientific notation to be added or subtracted, they need to have the same exponent, which removes options b and c.

Moving the second number for 10^3 to 10^5 would be equivalent to a multiplication by 100, hence we have to divide by 100 at the base, that is:

2.6 x 10^3 = (2.6/100) x 10^5 = 0.026 x 10^5.

Answer:

he traveled 900 feet

Step-by-step explanation:

250 + 650 = 900

Mr. Carter traveled a total distance of 900 feet from his boat to where he ended up.

Here, we have to find the total distance that Mr. Carter traveled from his boat to where he ended up, we need to calculate the sum of the distances above and below sea level.

The distance above sea level is 250 feet (his house boat's level), and the distance below sea level is 650 feet (where he ended up after jumping).

Total distance traveled = Distance above sea level + Distance below sea level

Total distance traveled = 250 feet + 650 feet

Total distance traveled = 900 feet

Mr. Carter traveled a total distance of 900 feet from his boat to where he ended up.

A) The unit prices are the same.

Step-by-step explanation:

First convert dollars to cents to make the calculation easier

Package of 50 paper plates costs $2.50
$2.50 = 2.50 x 100 = 250¢
So the unit price, which is the price per paper plate = 250/50 = 5¢

Package of 80 paper plates costs $4.00
$4.00 = 4.00 x 100 = 400¢
So the unit price, which is the price per paper plate = 400/80 = 5¢

So the unit prices of both packages are the same

The equation 3(4x + 12) = 2(6x + 8) has no solution because the variable x was neglected as it equals 0.

It should be noted that the equation given is illustrated as:

3(4x + 12) = 2(6x + 8)

Open the parentheses

12x + 36 = 12x + 16

Collect like terms

12x - 12x = 16 - 36

0 = -20

Therefore, it has no solution.
