What is the sum of the complex numbers -9 - i and -5 - i?

1. -14 - 2i

2. 14 - 2i

3. 14 + 2i

4. -14 + 2i

Answer:

c = -12

Step-by-step explanation:

Quadratic Standard Form: ax² + bx + c

Step 1: Write equation

3x² + 6x = 12

Step 2: Subtract 12 on both sides

3x² + 6x - 12 = 0

Here, we have the standard form of the quadratic. We see that our c = -12

Answer:

65

Step-by-step explanation:

650x0.1=65

the answer is 65 dollars uwu

Answer:

$65

Step-by-step explanation:

10% of 650 is 65 because you multiply .1 and 650, or move the decimal one place to the left. because the question asks for the discount price, you would just find the discount.

Step-by-step explanation:

Hey, there!!

Here,

3(2x-5)=25 is given.

To slolve: x

Now,

Multiply (2x-5) by 3.

6x-15 = 27.

Shift (-15) on right side.

6x= 27+15

or, 6x= 42

Divide 42 by 6.

[tex]x = \frac{42}{6} [/tex]

Therefore, x= 7.

Hope it helps....

[tex]\boxed{x = 7}[/tex]

Let's solve your equation step-by-step.

[tex]3(2x-5)=27[/tex]

Step 1: Simplify both sides of the equation.

[tex]3(2x-5)=27[/tex]

[tex](3) (2x) + (3) (-5) = 27[/tex] (Distribute)

[tex]6x + -15 = 27[/tex]

[tex]6x - 15 = 27[/tex]

Step 2: Add 15 to both sides.

[tex]6x -15 + 15 = 27 + 15[/tex]

[tex]6x = 42[/tex]

Step 3: Divide both sides by 6.

[tex]\frac{6x}{6} = \frac{42}{6}[/tex]

Answer:

[tex]\huge\boxed{D, x -4}[/tex]

---- Starting with: ----

x² - 10x + 24

Since we have a leading coefficient of 1, simply find two numbers that sum up to -10 and multiply into 24.

By guessing and checking, we get the numbers -6 and -4. Put these into factors:

(x - 6)(x - 4)

Therefore, a binomial present in factored form is D. x - 4

Answer:

13.2

Step-by-step explanation:

Given

[tex]10x = 132[/tex]

Required

Determine the initial quantity

The interpretation of this question is to solve for the value of x

To start with:

[tex]10x = 132[/tex]

Divide both sides by 10

[tex]\frac{10x}{10} = \frac{132}{10}[/tex]

[tex]x = \frac{132}{10}[/tex]

[tex]x = 13.2[/tex]

Hence, the initial quantity is 13.2

Answer:

[tex]A=73.5\text{ cm}^2[/tex]

Step-by-step explanation:

The formula for an area of a triangle is:

[tex]A=\frac{1}{2}bh[/tex]

Where b is the base length and h is the vertical height.

From the triangle, we can see that the base is 21 cm while the vertical height is 7. Thus:

[tex]A=\frac{1}{2}(7)(21)[/tex]

Multiply:

[tex]A=\frac{1}{2}(147)[/tex]

Multiply:

[tex]A=73.5\text{ cm}^2[/tex]

And that's our answer :)

The Area of triangle is 73.5 square cm.

We have from the figure,

Base of triangle = 21 cm

Height of triangle = 7 cm

side of triangle = 15 cm

We know the formula for Area of Triangle

Area of Triangle = 1/2 x base x height

Now, plugging the value of base and height in the formula we get

Area of triangle = 1/2 x  base x height

= 1/2 x 21 x 7

= 147/2

= 73.5 square cm

Answer:

[tex]\huge \boxed{{10x^2 + 12x \mathrm{\ units^2 }} }[/tex]

Step-by-step explanation:

area of shaded region = area of whole rectangle - area of unshaded region

Area of a rectangle is length × width.

A = 5x(3x+2) - (x(5x-2))

Expand brackets.

A = 15x² + 10x -(5x² - 2x)

Distribute negative sign.

A = 15x² + 10x - 5x² + 2x

Combine like terms.

A = 10x² + 12x

Step-by-step explanation:

Answer:

y = 9/5

4th Option

Step-by-step explanation:

Step 1: Write out function f(y)

f(y) = 5y - 3

Step 2: Define variable from problem

f(y) = 6

Step 3: Replace variable

6 = 5y - 3

Step 4: Add 3 to both sides

9 = 5y

Step 5: Isolate y by dividing both sides by 5

y = 9/5

Question:

Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the  water. At the end of his jump, Danny was 2.3 meters below the surface of the water.

The following equation describes this situation  14.2 + (-16,5) = -2.3 .

What does -16.5 tell us?

Answer:

The displacement between his current position and his initial position

Step-by-step explanation:

Given

[tex]Initial\ Position = 14.2m[/tex]

[tex]Final\ Position = -2.3m[/tex]

[tex]14.2 + (-16.5) = -2.3[/tex]

Required

What does -16.5 represents?

To understand this, we need to first calculate the displacement between his initial and final position

[tex]Displacement = Final\ Position - Initial\ Position[/tex]

[tex]Displacement = -2.3m - 14.2m[/tex]

[tex]Displacement = - 16.5m[/tex]

So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

[tex]\bold{y=1.5\times 2^x+4}[/tex]

Step-by-step explanation:

Given:

Exponential function with common ratio 2.

Horizontal asymptote at y = 4

Passes through point (2, 10)

To find:

Equation of the exponential function ?

Solution:

Equation for an exponential function may be given as:

[tex]y=ab^x+c[/tex]

Where b is the common ratio and

c is the y value of horizontal asymptote.

[tex](x, y)[/tex] are the points on the function.

We are given that:

b = 2

c = 4

Let us put all the given values and find equation.

[tex]y=a\times 2^x+4[/tex]

Now, let us put [tex]x = 2, y = 10[/tex] to find the value of a.

[tex]10=a\times 2^2+4\\\Rightarrow a\times 2^2=10-4\\\Rightarrow a\times 4=6\\\Rightarrow a =1.5[/tex]

[tex]\therefore[/tex] the equation of exponential function is:

[tex]\bold{y=1.5\times 2^x+4}[/tex]

Answer:

A. Width = 25   Length = 15

Step-by-step explanation:

Length = L = Width - 10

Width = W

Perimeter of a rectangle

=> 2 (L + B) = 80

=> 2 (W - 10 + W) = 80

=> 2 (2W - 10) = 80

=> 4W -20 = 80

=> 4W -20 + 20 = 80 + 20

=> 4W = 100

=> 4W/4 = 100/4

=> W = 25

Width = 25

Length = 25 - 10 = 15

So, the answer is A.

Answer:

The sale this month = 79

Step-by-step explanation:

Let the amount he needs to sell this month = x

[tex]Average = \frac{sum\ of\ individual\ data\ }{number\ of\ entries}[/tex]

[tex]Average= \frac{90\ +\ 45\ +\ 103\ +\ 68\ +\ x}{5}[/tex]

Note that number of entries = number of months = 5

To maintain an average sales of 77, the amount of sale in month 5 is determined as follows:

[tex]77 = \frac{306\ +\ x}{5} \\cross-multiplying\\77\ \times\ 5\ = 306\ +\ x\\385 = 306\ +\ x\\x =385\ -\ 306\\x = 79[/tex]

Answer:

418.2477796 m

Step-by-step explanation:

You divide it in to a rectangle and 2 half circles (which will make a whole circle if added together) and solve them.

P= 2( L + W) - - > 2 ( 102 + 60)= 324

Cf= 2лr^2 - - - > 2л(30)^2=30л

324 + 30л = 418.2477796 m

Answer:

n = -6

Step-by-step explanation:

You will collect like terms

10(6n+6+5n-5)=13(35+7n-25+3)

it will give you this

10(11n+1)=13(10+10n)

Then you remove the parenthesis

110n+10 = 130 +130n

Move the terms

110n -130n = 130-10

collect like terms

-20n=120

divide both sides

Step-by-step explanation:

Answer:

(-10,8)

Step-by-step explanation:

So our original point is (-6,9).

A translation of 4 units to the left means that the x-value would go left by 4. In other words, we subtract 4 to -6. We subtract because going to the left means that it's going to the negative direction.

A translation of down 1 unit means that the y-value would go down by 1. In other words, we subtract 1. Again, we subtract because going downwards means that it's going to the negative direction.

Therefore, the new point would be:

1.5 + 2y = 20

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We subtract 1.5 from both sides.

2y = 20 - 1.5

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Subtract 1.5 from 20 to get 18.5.

2y = 18.5

Divide both sides by 2.

[tex]y = \frac{18.5}{2}[/tex]

Reduce the fraction [tex]\frac{185}{20} = 9.25[/tex] to lowest terms by extracting and canceling out 5.

[tex]y =\frac{37}{4}[/tex].

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[tex]\frac{37}{4} = 9.25[/tex] in decimal form.
