Answer:

21 + 12i

Step-by-step explanation:

Given

(3 - 4i)(1 + 5i) - (2 - i) expand the product of factors

= 3 + 11i - 20i² - 2 + i

= 3 + 11i + 20 - 2 + i  collect like terms

= 21 + 12i

Step-by-step explanation:

Answer:

1/2 x 1/10 = 2/100

1/2 + 1/10 =  6/10

1/2 - 1/10 =  4/10

1/2 divided by 1/10 = 5

1) 6r + 7 = 13 + 7r    - Subtract 6r from both sides...

   7 = 13 + r       - Subtract 13 from both sides....

 6(-6) + 7 = 13 + 7(-6)

  -36 + 7 = 13 -42

   -29 = -29  ( It works )

2) -14 + 6b + 7 - 2b = 1 + 5b    - Combine like terms...

   -7 + 4b = 1 + 5b        - Add 7 to both sides....

    4b = 8 + 5b       - Subtract 5b from both sides....

     -b = 8            - Divide both sides by -1

3) 8x + 4(4x+3) = 4(6x + 4) - 4     - Distributive property

   8x + 16x + 12 = 24x + 16 - 4        Combine like terms

   24x + 12 = 24x + 12       - Both terms equal each other

    0 = 0

Since both terms equal each other, all numbres fit.

hope my answer helps you

Step-by-step explanation:

Yes that is definitely possible. You will have to either double up on geometry and algebra II or algebra II and pre-calculus. At my high school, there were multiple people that did the latter. I also knew someone that doubled up on pre-calculus and calculus I, but I don't recommend that.

For this sort of problem, you need to be familiar with prefixes.

So:

megabyte = [tex]1 *10^6[/tex] bytes

kilobyte = [tex]1*10^3[/tex] bytes

and a regular byte would just be [tex]1[/tex]

Now, you will need to do a conversion:

[tex]1megabyte*\frac{1*10^6bytes}{1megabyte}*\frac{1*10^{-3}kilobyte}{1byte}[/tex]

I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are [tex]1*10^6[/tex] bytes!)

In the second fraction thought, remember one kilobyte is [tex]1*10^3[/tex] bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do [tex]\frac{1kilobyte}{1*10^3bytes}[/tex], but I think it is more correct to do write it out how I did).

*** They do equal the same thing though! Do whichever way is easier for you!

Now, your answer should be:

[tex]10^3[/tex] kilobytes (1000 kilobytes)

Hope this helped!

Answer: 2/5

Explanation: Ask if you want an explanation!

      The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.

Finding the Slope

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)      

                                          =  (5 - 1) ÷ (8 - (-2))    

                                          =   ⁴/₁₀

                                          = ²/₅  

Checking my answer:

We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y - 1 =  ²/₅ (x + 2)

In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.

Answer:

x = 7

Step-by-step explanation:

y = 14

14 x 2 = 28

Therefore:

3.5 x 2 = 7

Value of y is 112 when value of x is 28

Given that;

Value of y is 14 when x = 3.5

Find:

Value of y when value of x = 28

Computation:

We know that, y is directly proportional to x

So,

[tex]Value\ of\ y = 14[\frac{28}{3.5} ] \\\\Value\ of\ y = 14[8]\\\\Value\ of\ y = 112[/tex]

Answer:

x=20

Step-by-step explanation:

-12+x=8

Add 12 on both sides (-12 + 12 + x = 8 + 12)

which crosses out -12

and then you get x=20

Answer:

62.5%

Step-by-step explanation:

Step-by-step explanation:

If everything is kept in terms of x then:

For part A the general area would just be side times side.

Here it would be (30x)(4x)

=[tex]120x^{2}[/tex]

For part B since you have 5 sections divide the long side by 5.

[tex]\frac{30x}{5} =6x[/tex]

Then multiply by the other side of the rectangle to find the area of one section.

6x(4x)=[tex]24x^{2}[/tex]

Alternatively you could just divide the large area by 5 to get the area of one section.

[tex]\frac{120x^{2} }{5}=24x^{2}[/tex]

Answer:

x > -3.4

Step-by-step explanation:

1 < (x + 5.5) / 2

first multiply each side by 2

2 < x + 5.5

Then subtract 5.5 from each side

-3.4 < x

x has to be on the left so you switch the hole equation around to get

x > -3.4

Answer: x≤360

Step-by-step explanation:

The perpendicular bisector of a line divides the line into two equal segments and is perpendicular to the line

The perpendicular distance of point P from the line l is equal to the distance of the lost point s from the line l and points P and s are on opposite sides of the line l

The point s can be marked by constructing the perpendicular to line l passing through P

The steps to construct a perpendicular line from a point to a line and mark point s are given as follows;

The constructed point s above is the required point and points P and s are located on opposite sides of the line l

Answer:

$2091

Step-by-step explanation:

We know:

12.75 per hour (h)

41 hours each day twice a week: each week (41 x 2) = 82

Since it is asking for two weeks: 82 x 2 = 164 hours

164 x 12.75 = $2091
