Answer:

-3

Step-by-step explanation:

I reduced it

Answer:

The answer would be -3 because a negative number multiplied by a positive number would make it a negative number for the answer.

Step-by-step explanation:

Let the larger integer be x

Hence, the smaller integer = x-2

Hence,

Reciprocal of the x= 1/x

Reciprocal of x-2= 1/ x-2

Hence. their sum=

[tex] \frac{1}{x} + \frac{1}{x - 2} \\ = \frac{x - 2 + x}{x(x - 2)} \\ = \frac{2x - 2}{ {x}^{2} - 2x} [/tex]

The sum of the reciprocals of two consecutive even integers if the larger integer is [tex]x[/tex] is [tex]\frac{2}{x}[/tex].

For two consecutive even integers, if the larger integer is [tex]x[/tex], then the smaller one is [tex]x-2[/tex].

Their reciprocals will be [tex]\frac{1}{x}[/tex] and [tex]\frac{1}{x-2}[/tex].

Now, the sum of the reciprocals is [tex]\frac{1}{x} + \frac{1}{x-2}[/tex]

[tex]= \frac{1}{x} + \frac{1}{x-2}[/tex]

[tex]= \frac{x-2+x}{x(x-2)}[/tex]

[tex]= \frac{2x-2}{x(x-2)}[/tex]

[tex]= \frac{2(x-2)}{x(x-2)}[/tex]

[tex]= \frac{2}{x}[/tex]

So, the sum of the reciprocals of two consecutive even integers if the larger integer is [tex]x[/tex] is [tex]\frac{2}{x}[/tex].

Answer:

2.1 months

Step-by-step explanation:

Let x represent the number of months

Set up expressions to represent the cost of each Internet provider

40x + 39 will represent the first one

30x + 60 will represent the other

Set these equal to each other and solve for x:

40x + 39 = 30x + 60

10x + 39 = 60

10x = 21

x = 2.1

So, the cost will be the same in 2.1 months

Answer : -5

Step by Step Explanation:

You first combine like terms which is -38 and 7, so subtract the 7 from the right and add it to -38.

That will give you 45. Then divide 9x and -45 by 9. That will give you -5

Step-by-step explanation:

Answer:

The value is [tex] E(k) = \frac{68}{52}[/tex]

Step-by-step explanation:

From the question we are told that

The total number of cards is [tex]n = 52[/tex]

Let k represent the winnings and loss when any card is drawn

So k = $5 when a faced card is drawn

So k= $ 20 when an Ace card is drawn

So g = - $2 when any other card is drawn

Generally in a standard deck of card

The number of Ace is 4

The number of queen is 4

The number of jack is 4

Therefore the number off faced cards is

R = 4 + 4 + 4 = 12

Generally the number of other cards is

Y = n - R

=> Y = 52 - 12

=> Y = 36

Generally the probability of drawing a faced card is mathematically represented as

[tex]P(k = 5) = \frac{ 12}{52}[/tex]

Generally the probability of drawing a Ace card is mathematically represented as

[tex]P(k = 20) = \frac{ 20}{52}[/tex]

Generally the probability of drawing a other card is mathematically represented as

[tex]P(k = -2) = \frac{ 36}{52}[/tex]

Generally the expected profit from any one draw is mathematically represented as

[tex]E(k) = \sum k_i * P(K = k)[/tex]

=>    [tex]E(k) =  5 * \frac{ 12}{52}  + 20\frac{ 20}{52} + [- 2 * \frac{ 36}{52}][/tex]

=> [tex] E(k) = \frac{68}{52}[/tex]

Answer:

x = -5, 7

Step-by-step explanation:

Step 1: Write equation

x² - 2x - 35 = 0

Step 2: Solve for x

Factor: (x - 7)(x + 5) = 0

Find roots: x = -5, 7

Step 3: Check

Plug in x to verify if it's a solution.

(-5)² - 2(-5) - 35 = 0

25 + 10 - 35 = 0

35 - 35 = 0

0 = 0

7² - 2(7) - 35 = 0

49 - 14 - 35 = 0

35 - 35 = 0

0 = 0

Step-by-step explanation:

Answer:

b=2.5

Step-by-step explanation:

We know that,

Area of a rectangle= Length X Breadth

Perimeter of a rectangle= 2( Length + Breadth)

From the provided information we get that,

Area= Perimeter

lb=2(l+b)

Substituting l=10,

10b=2(10+b)

10b=20+2b

10b-2b=20

8b=20

b=20/8

b=2.5

Answer:

  82/99

Step-by-step explanation:

1. Notice the length of the repeating pattern.

  the pattern is 82 repeating, a 2-digit pattern

2. Notice where the repeating pattern starts, relative to the decimal point.

  the repeating starts at the decimal point

3. If the repeating starts at the decimal point, use a pattern of repeating 9s of the same length as the denominator of the fraction

  2 nines are the denominator: 82/99

4. Reduce the fraction if possible

  this fraction cannot be reduced

As a simplified fraction, 0.828282... = 82/99

_____

Comment on more complicated cases

If the repeat does not start at the decimal point, or if the number contains an integer part, then the numerator of the fraction is found in a slightly different way. Let n be the number of repeating digits of the number x. The fraction is then ...

  (10^n·x -x)/(10^n -1)

Example:

  1.2345345345...        a number with a 3-digit repeat not starting at the decimal point

  (1234.5345... -1.2345...)/(1000 -1) = 1233.3/999  = 4111/3330

The multiplication by 10^n aligns the repeating parts so they cancel when you do the subtraction.

Answer:

  a)  A = {-3, -2, -1}

  b)  n(A) = 3

  c)  A is finite

Step-by-step explanation:

a) The elements of A are the integers between -4 and 0, not including those values. Those integers are -3, -2, -1, so those are the elements of set A.

  A = {-3, -2, -1}

__

b) n(A) is the number of elements in set A. Obviously, there are 3:

  n(A) = 3

__

c) Since n(A) is not "infinity", the set A is finite.

Answer:

  544 units²

Step-by-step explanation:

The surface area is the sum of the areas of the three rectangular faces and the two triangular bases.

  SA = 10×14 +10×14 +12×14 + 2(1/2)(12)(8)

  = 14×(10+10+12) +12×8

  = 448 +96

  = 544 . . . . square units

_____

The area of a rectangle is the product of its dimensions:

  A = LW

The area of a triangle is half the product of its base and height:

  A = (1/2)bh

Here, both triangles have the same area, so we multiplied the area of one of them by 2 to get the area of both of them.
