An encryption key is used to help decrypt messages. True or False. Explain why

Answer:

The first option

Step-by-step explanation:

Because when you multiply the first equation by 2, it sets the -x to -2x which helps cancel the variable out allowing you to easily solve the system of equations.

Answer:

make the denominators ( bottom number ) the same and whatever u do to that do to the top

Step-by-step explanation:

e.g ½ - ⅓

make the common denominator 6

to get from 2 to 6 u times by 3 so it wud be 3/6

and then to get from 3 to 6 u times by 2 so do the same to the numerator (top number) so u get 2/6

3/6 take away 2/6 is 1/6

:)

Step-by-step explanation:

Make sure the denominators (thats the bottom number) are the same!! This is very important!! For example, if you are subtracting 3/10 from 1/2 you are going to multiply 1/2 by 5 (because 2×5 is 10) and get 5/10. Now, what you are going to do is subtract 4 from 5 and get 1/10. I hope this helped!

To find the average rate of change, we divide the change in the output value by the change in the input value.

Answer:

No, The sum of the lengths of sides b, c must be greater than the length of the remaining side a.

Answer:

D) x = 65

Step-by-step explanation:

I just tried B) x = 2.6 and it was wrong.

The true value of x in the equation is 65

The equation is given as:

[tex]\frac{x}5 - 2 = 11[/tex]

When x = 1.8, we have:

[tex]\frac{1.8}5 - 2 = 11[/tex]

[tex]-1.64 = 11[/tex] -- this is false

When x = 2.6, we have:

[tex]\frac{2.6}5 - 2 = 11[/tex]

[tex]-1.48 = 11[/tex] -- this is false

When x = 45, we have:

[tex]\frac{45}5 - 2 = 11[/tex]

[tex]7 = 11[/tex] -- this is false

When x = 65, we have:

[tex]\frac{65}5 - 2 = 11[/tex]

[tex]!1 = 11[/tex] -- this is true

Hence, the true value of x in the equation is 65

Given:

A bag contains 21 red marbles, 24 green marbles, and 21 blue marbles.

To find:

What color marble will you most likely choose if you choose a marble at random from the bag.

Solution:

We have,

Number of red marbles = 21

Number of green marbles = 24

Number of blue marbles = 21

Total number of marbles = 21+24+21

                                         = 66

Now,

[tex]P(Red)=\dfrac{21}{66}[/tex]

[tex]P(Green)=\dfrac{24}{66}[/tex]

[tex]P(Blue)=\dfrac{21}{66}[/tex]

The number of green marbles is largest. So, the probability of getting a green marble is largest.

Therefore, you will most likely choose green marble.

Answer:

The area of the rectangle is equal to the base times the height. That is, major side by minor side. In many places we will find how the height is called "h" and the base "b."

Step-by-step explanation:

The dimensions of rectangle are width of 5cm and Length of 28 cm.

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees

The perimeter of rectangle is

Perimeter=2(Length+width)

Given that  length is 3 more than five times its width.

L=3+5W

Perimeter=2(3+5w+w)

Perimeter of rectangle is given by 66cm

66=2(6w+3)

Apply distributive property on RHS side

66=12W+6

Subtract 6 from both sides

60=12W

Divide both sides by 12

W=5

L=3+5(5)=25+3=28

Hence the dimensions of rectangle are width of 5cm and Length of 28 cm.

2/3 is the slope, rise over ruj

Answer:

slope = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

To find the slope of a line, use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point on the line.

So, this formula requires two points from the line. Reading the graph, we can see that the two points marked on the line are (-3,-4) and (3,0). Thus, use the x and y values of those two points, substitute them in the appropriate order into the formula, and solve:

[tex]\frac{(0)-(-4)}{(3)-(-3)} \\= \frac{0+4}{3+3} \\= \frac{4}{6} \\= \frac{2}{3}[/tex]

Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

Answer:

  yes, 4

Step-by-step explanation:

We assume your sequence is supposed to be ...

  -7, -3, 1, 5

First differences are ...

  -3 -(-7) = 4

  1 -(-3) = 4

  5 -1 = 4

These differences are constant, so we can conclude the sequence is an arithmetic sequence, and the common difference is 4.
