Answer:

5 + i

Step-by-step explanation:

Combine real part ans combine imaginary parts

2 + 3i + 3 - 2i = 2 + 3 + 3i - 2i

                      = 5 + i

Answer:

5 and 1i

Step-by-step explanation:

So you’re adding the following complex numbers: (2 + 3i) + (3 - 2i)

normally if you see a (-) in front of a number, that means it’s negative so we’re gonna think about this as -2i and positive 3.

so you’re gonna want to take the 2 regular while numbers (without the variable) and then add those together. they’re like numbers so neither of them have a variable, which means they can easily be added, but you can’t add a number like 7 to a number like 9h because there’s a variable.

Now that you’ve added the 2 and 3, you get 5 right? so now you’re gonna take the 3i and -2i, and add those together. since the number 3i is bigger than -2i, the ending number after you add those is gonna be positive, and it’s gonna be 1i.

now i’m not sure if you’re supposed to make an equation out of this but you’re answer will be 5 and 1i or 5 + 1i

also if you don’t want to put 1i, 1i is the same as just “i”. so you can put 5 + i :)

hope this helped!!

Step-by-step explanation:

Answer: 150c + 400t ≥ 4900

Step-by-step explanation:

Let the number of chairs sold = c

Let the number of tables sold = t

Price for each chair = $150

Price for each table = $400

The inequality that could represent the number of tables and chairs sold will be:

(150 × c) + (400 × t) ≥ 4900

150c + 400t ≥ 4900

Answer:

  $112

Step-by-step explanation:

The amount of interest is given by the formula ...

  I = Prt

where P is the principal earning interest at annual rate r for t years.

  I = $400 · 0.08 · 3.5

  I = $112

The amount would earn $112 in interest by the end of 3 1/2 years.

Answer:

5x+35

Step-by-step explanation:

the parentheses means that you can multiply the outer number (5) with the inner numbers/variables

5*x=5x

Answer:

D)    < 3, 7)>

Step-by-step explanation:

Explanation:-

Given that the vector < 3 , -7 >

Given the vector reflection across the x-axis

                   (x,y) → (x , -y)

The vector < 3,-7> →< 3, -(-7)>

                  < 3,-7> →< 3, 7)>

Answer:

6p - 2

Step-by-step explanation:

The expression that needs to be made in this question refers to the total number of people that signed the petition. To calculate this we need to add the total number of signatures that both you and your friend were able to acquire. Once we do this we simply combine like terms in order to simplify the expression as much as possible.

4p + 5 + 2p - 3

4p + 2p + 5 - 3

6p - 2

Therefore, the total and simplified expression for the total number of signatures would be 6p - 2

Answer:

The function have a constant ratio

No, it does not represent an exponential function.

Step-by-step explanation:

As given,

Ines has saved $5. She doubles the amount she saves each week.

⇒ In first week she saved = $5

   In second week she saved = 2×$5 = $10

   In third week she saved = 2×$10 = 20

  In fourth week she saved = 2×$20 = 40

and so on..

∴ we get the series

5, 10, 20, 40 ,.......

If the series is given as a, b, c, d, ..... , then

The common difference is defined as d = b-a = c-b

The common ration is defined as r = [tex]\frac{b}{a} = \frac{c}{b}[/tex]

Here, in the given question

The series is - 5, 10, 20, 40

This has no common difference , d =   10 - 5 (= 5 )≠ 20 - 10 (= 10)

As 5 ≠ 10

So the function does not define common difference .

Now,

This has common ratio , r =  [tex]\frac{10}{5} (=2) = \frac{20}{10}(=2)[/tex]

As 2 = 2

So, the function represent common ratio

Now,

The function does not represent an exponential function because it is increased by common ratio.

Answer:

x = 22

Step-by-step explanation:

x = 7 + 15

x = 22

Answer:

x = 22

Step-by-step explanation:

1x - 7 = 15

1x = 15 + 7

1x = 22 (divide both sides by the first number/1 to get x)

1x/1 = 22/1

x = 22

Have a great day!!

Step-by-step explanation:

8a + 16c

8(a + 2c)

answer is C

Part B

8(-5) + 16(-1)

-40 - 16 = -56

Answer:

PART A: 8(a + 2c)

PART B: -56

Step-by-step explanation:

PART A:

8a + 16c

8(a) + 8(2c)

8(a + 2c)

PART B:

8a + 16c

if a = -5, and c = -1,

8(-5) + 16(-1)

-40 + -16

= -56

Answer:

Miles would be the best.

Step-by-step explanation:

Miles are the largest way to measure land, so I would use that.

Miles

When measuring that far of a distance, you want to use the largest unit of measurement, because measuring in inches or centimeters is unrealistic.

Answer:

$4140 + $294d

Step-by-step explanation:

Hello,

Let's write down what we know first,

d days

14 food baths -- $175 and $8 per day

26 game booths -- $65 and $7 per day

What we want to find the amount of money paid for both food baths and game booths so after finding them individually, we need to add them up.

We already know the company rents out 14 fb and 26 gb and we know that each fb is 175 dollars and each gb is 65 dollars, so we should find out the cost of buying them. We can also write out the total cost of

14 * $175 = $2450

26 * $65 =  $1690

Now lets find the per day cost,

14 * $8 * d = $112d

26 * $7 * d = $182d

With both equations added together we get,

$2450 + $112d

$1690 + $182d

Add those together and we get:

$4140 + $294d

Answer:

B

Step-by-step explanation:

36 ÷ 3 = 12 is basically the division version of the original equation. None of the other equations equal the same answer so B is the correct option.

36 ÷ 3 = 12 is equivalent to 3 • 12 = 36
