The complex numbers are [tex]\(5i - 2\)[/tex] and [tex]\(5i + 2\)[/tex], meeting the conditions: sum [tex]\(10i\)[/tex], difference [tex]\(-4\)[/tex], product [tex]\(-29\)[/tex].

Let's denote the two complex numbers as [tex]\(a\)[/tex] and [tex]\(b\)[/tex].

Given:

1. [tex]\(a + b = 10i\)[/tex]

2. [tex]\(a - b = -4\)[/tex]

3. [tex]\(a \times b = -29\)[/tex]

From the first equation, we can isolate one variable in terms of the other:

[tex]\[ a = 10i - b \][/tex]

Now, substitute this expression for [tex]\(a\)[/tex] into the second and third equations:

[tex]\[ (10i - b) - b = -4 \][/tex]

[tex]\[ 10i - 2b = -4 \][/tex]

[tex]\[ 2b = 10i + 4 \][/tex]

[tex]\[ b = 5i + 2 \][/tex]

Now that we have found [tex]\(b\)[/tex], we can substitute it back into the expression for [tex]\(a\)[/tex] to find [tex]\(a\)[/tex]:

[tex]\[ a = 10i - (5i + 2) \][/tex]

[tex]\[ a = 10i - 5i - 2 \][/tex]

[tex]\[ a = 5i - 2 \][/tex]

So, the two complex numbers are [tex]\(5i - 2\)[/tex] and [tex]\(5i + 2\)[/tex]. Both of these satisfy the given conditions.

Final answer:

The next number in the arithmetic sequence 10, 23, 36, ? is 49.

Explanation:

The given sequence is an arithmetic sequence, where each number is obtained by adding a fixed value (the common difference) to the previous number. To find the next number in the sequence, we need to determine the common difference and add it to the last number in the sequence.

Looking at the given sequence: 10, 23, 36, ?, we can see that the common difference is 13, as each subsequent term is obtained by adding 13 to the previous term.

Therefore, to find the next term in the sequence, we add 13 to the last term, which is 36. So, the next number in the sequence is 49.

Hey there!!

Given equation :

... c(x) = 29x + 54.5

In this equation $54.50 is installation fee and this would remain as a constant. ( This value wouldn't change ).

'x' is represented as the number of months.

The total cost or c(x) is given as $344.50

Getting this into equations :

... 344.50 = 29x + 54.5

Subtracting 54.5 on both sides :

... 29x = 290

Dividing by 29 on both sides :

... x = 10

Hence, the number of months is 10.

Hope my answer helps!!

By manipulating the provided cost function, we find that with $344.50, you can afford 10 months of cable service.

To determine the number of months of cable service you can have for $344.50, you simply need to solve the equation C(x) = 29x + 54.5 = 344.5, where C(x) represents the cost of the service and x is the number of months you are paying for. We can start by subtracting the installation fee (54.5) from both sides of the equation, which gives us 29x = 290. Then, dividing through by 29, we arrive at x=10.

Therefore, you can have cable service for 10 months if you have $344.50.

The answer is 122.5 using long division

720/6=120

15/6=2.5

735 divided by 6, or in standard form, [tex]735/6[/tex], is a division problem.

In order to divide 735 by 6, you must first:

See how many times 6 goes into 7: 1 time

6*1=6

Then subtract 6 from 7 (which comes from the 7 in the hundreds place): Which gives you 1

Then bring down the 3 and combine it with 1: Which gives you 13

Once you do that, see how many times 6 goes into 13: 2 times

6*2=12

Subtract 12 from 13: You get 1

Then bring down the 5 and combine it with the 1: Which gives you 15

Finally, see how many time 6 goes into 15: 2 times

6*2=12

Subtract 12 from 15: You get 3

This means that the answer is: 122 with a remainder of 3

This is the process:

Answer:

6

Step-by-step explanation:

rise = 6

---------------------

run = 1

Rise is the y axis and run is the x axis. You look at the point and first go either up or down to the point you need to stop at. In this case we go down. Run is when you go sideways. Once you reach the line where the point lies, you need to go sideways 1 time to get to the point. Since rise is over run, 6 over 1

Therefore...........

6 over 1 = 6!!!!

Answer:

n= -4

Step-by-step explanation:

First we have to find the equation of line which passes through (6,3) and (8,4).

Then we have to pass this line through the point (n , -2).

we know, equation of line passing through (x1,y1) and (x2,y2) is

[tex]\frac{x-x1}{x1-x2}=\frac{y-y1}{y1-y2}[/tex]

So, the equation of line passing through (6,3) and (8,4) is

[tex]\frac{x-6}{6-8}=\frac{y-3}{3-4}[/tex]

or, [tex]\frac{x-6}{-2} =\frac{y-3}{-1}[/tex]

multiplying both sides by  -2

x-6=2(y-3)

or, x-6=2y-6

or, x-2y=6-6

or, x-2y=0

Now, we have to pass this line through  (n,-2)

So, using the point in the line, that is using  x=n  , y=-2

we get

n-2(-2)=0

or, n+4=0

or, n=-4

Answer:

Step-by-step explanation:

Given that the line passes through

(6,3), (8,4), and (n,-2).

We have to find the value of n.

Let us name the points as A, B and C in that order

Slope of AB = slope of BC since all 3 points lie in the same line

To find slope of AB:

Slope = (y2-y1)/(x2-x1) = (4-3)/(8-6) = 1/2

To find slope of BC:

Using the same formula slope = (-2-4)/(n-8) = -6/(n-8)

The two slopes are equal.

Hence 1/2 = -6/(n-8)

n-8 = -12

n = -4

If 4 - 3 + 5 = -6 + 8 + 4 is a mathematically correct statement, then both sides should end up with the same number:

4 - 3 + 5 = -6 + 8 + 4     Original statement.

1 + 5 = -6 + 8 + 4     You can do this in any order, but I start by doing the 4 - 3.

6 = -6 + 8 + 4     Finish simplifying the left side.

6 = 2 + 4     Combine the -6 and 8.

6 = 6     Finish simplifying the right side.

Because both sides are equal to each other, the sentence must be true.

Therefore, the sentence is true because when simplified, the statement is 6 = 6.

Hope this helps! :)

EDIT: Just incase anyone is curious, both this way and the way the other guy used both work, as they both prove that both sides are equal.

Chemical changes in mixtures can be identified by the creation of a new substance, a change in color or odor, production of gas, or formation of a precipitate. When two clear liquids change color or form a new solid upon mixing, as happens with silver nitrate solution and copper wire, or potassium iodide and lead nitrate, a chemical change has occurred.

In order to identify which of the four mixtures has undergone a chemical change, we need to look for indications of that change. There are several telltale signs of a chemical reaction. Such signs include the creation of a new substance, a change in color or odor, the production of gas (bubbles), or the formation of a precipitate (a solid that forms from a liquid mixture).

If two clear liquids mix and then change color, as seen when copper wire is immersed in an aqueous solution of silver nitrate and the solution turns blue, a chemical change has likely occurred. The copper wire also becomes covered with a gray solid, demonstrating the creation of a new substance. Another example is when two solutions, potassium iodide and lead nitrate, mix and form a solid, or precipitate, of lead iodide. This is another clear indication of a chemical change.

The mixture demonstrating a chemical change would exhibit characteristics such as a change in color, gas evolution, precipitate formation, or temperature change, indicating the formation of new substances.

In order to identify which mixture demonstrates a chemical change, it's essential to understand the characteristics of physical and chemical changes. Physical changes involve alterations in the state or appearance of a substance without forming new substances. On the other hand, chemical changes result in the formation of new substances with distinct properties.

If one of the mixtures exhibits a change in color, the evolution of gas, the formation of a precipitate, or a change in temperature, it suggests a chemical change. These are indicative of chemical reactions where bonds between atoms are broken and new ones are formed.

For instance, if a mixture produces a gas with effervescence, it implies the release of a new substance. Similarly, if a color change occurs, indicating the formation of a new compound, or if a solid precipitate forms, these are strong indicators of a chemical change.

Observing these characteristics in a mixture would signify a chemical reaction between the clear liquids, indicating the occurrence of a chemical change. It's crucial to analyze the physical and chemical properties of each mixture to pinpoint the one that demonstrates such transformative chemical processes.

Assuming that the question is "11 times 6" rather than "11x times 6". The answer would be 66.

The equation for this problem is: 11 + (11 x 6) - 11)

"11 more than" means you would add 11 to the next equation. "11 less than" means you would subtract 11 from the following equation.

According to Order of Operations, you would start with the expressions in the parenthesis. So we would start with "11 x 6", which is 66. Then the expression would become 11 + (66 - 11). We would do the expression the parenthesis, "66 - 11", and we would get the answer 55. The expression would become 11 + 55, and 11 + 55 is 66.

The arithmetic statement '11 more than 11 less than (11x6)' first requires you to do the multiplication, resulting in 66, then subtract 11 to get 55, and finally add 11 to get 66.

The mathematical statement "11 more than 11 less than (11x6)" is an arithmetic problem that requires several steps to solve. Firstly, compute the values in brackets. You must multiply 11 by 6, which results in 66. The next step is to understand what '11 less than' means. It means to subtract 11 from 66, which gives you 55. Then you interpret the last part of the statement: '11 more than', which means you add 11 to that 55. This finally gives you a sum of 66.

The missing phrase in Mackenzie's proof of the Vertical Angles Theorem is 'because they are both equal to 180 degrees'. This establishes that the sums of the angles are equal (since they are both supplementary), and allows her to then utilize the Subtraction Property of Equality to show that angle 1 is congruent to angle 3.

Mackenzie's paragraph proof for the Vertical Angles Theorem is almost complete. She has correctly identified that angle 1 and angle 4 are supplementary, as are angle 3 and angle 4, due to the fact that they each add up to 180 degrees. This establishes the equation: (angle 1 + angle 4) = (angle 3 + angle 4). The blank spot in Mackenzie's proof would need to be filled with the phrase 'because they are both equal to 180 degrees'. Mackenzie then correctly utilizes the Subtraction Property of Equality to state that, since the sums are equal, if you subtract angle 4 from both sides, you arrive at angle 1 = angle 3. Thus, completing the proof of the Vertical Angles Theorem: when two lines intersect, opposite or vertical angles are congruent, i.e., they have the same measure.
