Answer:

[tex]\Huge \boxed{3+16i}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

[tex]3+\sqrt{-16} * 6-\sqrt{-64}[/tex]

Using imaginary number rule : [tex]\sqrt{-n} =\sqrt{n} *i[/tex]

Where [tex]n[/tex] is a positive integer.

[tex]3+\sqrt{16} *i* 6-\sqrt{64}*i[/tex]

[tex]3+4i* 6-8i[/tex]

Multiplying.

[tex]3+24i-8i[/tex]

Combining like terms.

[tex]3+16i[/tex]

[tex]\rule[225]{225}{2}[/tex]

Answer:

3 + 16i

Step-by-step explanation:

3 + √-16 * 6 - √-64

= √-16 * 6 = 24i;    √-16 * 6;     √-16 = 4i

= 4 * 6i    multiply the numbers 4 * 6 = 24

= 24 i

√-64 = 8i;   √64    apply a radical rule

= √-1 √64

= √64  i;    √64 = 8

= 8i

= 3 + 24i - 8i

= 3 + 16i

Complete Question

You are given the dollar value of a product in 2016 and the rate at which the value of the product is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the terms of year t. (Let t=16 represent 2016)

2016 Value     Rate

$2150           $250 increase per year

Answer:

The  equation is  [tex]V(t) = 250 (t) + 4.3[/tex]

Step-by-step explanation:

Generally linear equation is represented mathematically as follows

      [tex]y = mx + c[/tex]

Where  y is the dependent variable which in this case is  dollar value of a product (V(t))

   x is the independent variable which in this case is the time in years(t)

  m is the slope which in this case is the  rate at which the value of the product is expected to change during the next 5 years

So  

        [tex]V(t) = m t + c[/tex]

When  t =  16  years

         [tex]2150 = 250 (16) + c[/tex]

=>       [tex]c = 4.3[/tex]

So the linear equation is  

      [tex]V(t) = 250 (t) + 4.3[/tex]

Assuming you are asking what does x represent when you say "What does represent" the answer is a: the number of days it take the brothers to paint 13 pictures.

The first 2 sentences are useless and don't tell you anything (well they do but you don't need the information).

Both brothers can paint 13 pictures in x days.

So x means days, more specifically, the number of days it took for the brothers to paint 13 pictures.

Answer:

Christopher needs 24 feet of fencing. Your rectangle should be 5x7 feet.

Step-by-step explanation:

Line PO is 5 feet wide, and we know that the side across from it is 5 feet wide. 5+5=10. The longer sides are supposed to be 2 feet longer than the shorter sides, so they have to be 7 feet long. 7+7=14. 10+14=24.

Answer:

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

So we know that:

[tex]f(3)=-2\text{ and } f(4)=-4[/tex]

This is the same as saying we have two coordinates: (3,-2) and (4,-4).

Let's find the equation of the linear function.

First, let's find the slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute (3,-2) for x₁ and y₁ and let (4,-4) be x₂ and y₂:

[tex]m=\frac{-4--2}{4-3}[/tex]

Simplify:

[tex]m=-2/1=-2[/tex]

So our slope is -2.

Now, use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Let's use (3,-2) for x₁ and y₁ and use -2 for m:

[tex]y+2=-2(x-3)[/tex]

Now, we can figure out the x-intercept.

Recall that the x-intercept is when the graph touches the x-axis.

In other words, the y-value would be 0. It will be (x,0).

So, to solve for the x-intercept, substitute 0 for y and solve for x:

[tex]0+2=-2(x-3)[/tex]

Simplify and distribute the right:

[tex]2=-2x+6[/tex]

Subtract 6:

[tex]-4=-2x[/tex]

Divide both sides by -2:

[tex]x=2[/tex]

So, our x-intercept is (2,0)

Answer: 50 km

Step-by-step explanation: So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by  

2.5 /1 . Then, 20 x 2.5=50. So the answer is 50 km

Answer:

B. 0.78

Step-by-step explanation:

0.78 would be closest to the nearest hundredth, depending on where the decimal is depends on how many numbers that come after the decimal.

Therefore 0.078 would be to the nearest thousandths and 7.8 would be to the nearest tenths.

Answer:

B

Step-by-step explanation:

I recommend simply using a calculator. If you divide 7/9 you would bet 0.7 (repeating). Round to the hundredths and you would get 0.78

Answer:

d =(m-q)/a

Step-by-step explanation:

[tex]q+ad=m\\ad = m-q\\\frac{ad}{a} = \frac{m-q}{a} \\\\d = \frac{m-q}{a}[/tex]

Answer:

d =  ( m-q)/a

Step-by-step explanation:

q+ad=m

Subtract q from each side

q-q+ad=m-q

ad = m-q

Divide each side by a

ad/a = ( m-q)/a

d =  ( m-q)/a

Answer:2

Step-by-step explanation: 12-8=4 4/2=2

Answer:

x = 2

Step-by-step explanation:

We can make an equation that meets the requirements stated.

Decreased signifies subtraction, so 12 will reduce the value after it. A number can be any letter you'd like, but I'll stick to x. Since 2 is multiplying that number, we can make 2 the coefficient. Finally, set it equal to 8.

12 - 2x = 8 Subtract 12 from both sides of the equation.

-2x = -4 Divide by -2 on both sides of the equation.

x = 2

Answer:

C

Step-by-step explanation:

So we have the equation:

[tex]3x-7=x+3[/tex]

Subtract x from both sides. The right cancels:

[tex](3x-7)-x=(x+3)-x\\2x-7=3[/tex]

Add 7 to both sides. The left cancels;

[tex](2x-7)+7=(3)+7\\2x=10[/tex]

Divide both sides by 2:

[tex](2x)/2=(10)/2\\x=5[/tex]

So, our answer is C

Answer:

C) x = 5

Step-by-step explanation:

A) 3(-5) - 7 = (-5) + 3

   -15 - 7 = (-5) + 3

   -23 = (-5) + 3

   -23 = -2 (they do not equal the same so no)

B) 3(2) - 7 = (2) + 3

    6 - 7 = (2) + 3

    -1 = (2) + 3

    -1 = 5 (they do not equal the same so no)

C) 3(5) - 7 = (5) + 3

    15 - 7 = (5) +  3

    8 =  (5) + 3

    8 = 8 (they equal the same so yes)

D) 3(-2) - 7 = (-2) + 3

    -6 - 7 = (-2) + 3

    -13 = (-2) + 3

    -13 = 1 (they do not equal the same so no)

Answer:

x = 51

Step-by-step explanation:

(x-3) /4 = 12

Multiply each side by 4

(x-3) /4 *4 = 12*4

x-3 = 48

Add 3 to each side

x-3+3 = 48+3

x = 51

Answer:

[tex]\Huge \boxed{x=51}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

[tex]\displaystyle \frac{x-3}{4} =12[/tex]

Multiplying both sides by 4.

[tex]\displaystyle \frac{x-3}{4} *4=12 *4[/tex]

[tex]x-3=48[/tex]

Adding 3 to both sides.

[tex]x-3+3=48+3[/tex]

[tex]x=51[/tex]

[tex]\rule[225]{225}{2}[/tex]

Answer:

Answer:

[tex]\huge\boxed{B. [1,2,3,........]}[/tex]

Step-by-step explanation:

[tex]9x - 4 < 13 x - 7[/tex]

Combining like terms

=> [tex]-4 + 7 < 13x-9x[/tex]

=> [tex]3 < 4x[/tex]

Dividing both sides by 4

=> [tex]x > \frac{3}{4}[/tex]

=> [tex]x > 0.75[/tex]

This means that x can be any number that is greater than 0.75

So, The solution set = [1,2,3,........]
