For a complex number, multiplying by the conjugate always gives which of the following? Select one: O A Non-negative complex number O B. Non-negative real number O C. Negative real number D. Positive rational number E. Negative irrational number​

Answer:

X=9 so D

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

70 and 12x + 2 are same- side interior angles and are supplementary, thus

12x + 2 + 70 = 180 , that is

12x + 72 = 180 ( subtract 72 from both sides )

12x = 108 ( divide both sides by 12 )

x = 9 → D

Answer

A.y-6=-5/4(x+2)

D.y-1=-5/4(x-2)

E.y-3.5=-1.25x

Step-by-step explanation:

The equation which represents the data values given in the table written in slope - intercept form is y = - 1.25x + 3.50

The data given :

X ____ Y

-2 ____ 6

0 ____ 3.5

2 ____ 1

4 ____ - 1.5

We could represent the equation in the form :

b = slope = Rise / Run

b = slope = Rise / Run c = intercept

From the table :

Slope = (y2 - y1) ÷ (x2 - x1) = (6 - (-1.5)) / (-2 - 4) = 7.5/-6 = -1.25

Using any pair of (x, y) values, we can obtain the intercept value :

Using ; (2, 1)

1 = -1.25(2) + c

1 = - 2.50 + c

1 + 2.50 = c

c = 3.50

Therefore, the equation becomes ; y = - 1.25x + 3.50

Answer:

The amount charged for a hamburger is $11

Step-by-step explanation:

The function relating the amount d charged with the number of hamburgers is;

d = 3h + 8

The amount charged for a hamburger can be calculated by substituting the value 1 for h

Thus, we have;

d = 3(1) + 8 = $11

Answer:

The constant of proportionality is 3.50.

Step-by-step explanation:

We know that when y directly varies with x, such that

[tex]y=kx[/tex]

The number 'k' is called the constant of proportionality.

Given the equation

[tex]y=3.50x[/tex]

as

[tex]y=kx[/tex]

so

[tex]k=3.50[/tex]           ∵ [tex]y=kx[/tex]

Here the value of k = 3.50, which is the constant of proportionality.

Therefore, the constant of proportionality is 3.50.

Answer:4.064 times

Step-by-step explanation:

Step 1

Area  of  Land owned by John =2.17 x 104 square miles

Area  of  Land owned by Sam= 5.34 x 103 square miles.

When we say about how many times is a quantity greeter than the other we mean that  how much is the smaller quantity contained in the larger quantity. and in such cases, we divide.

Area  of  Land owned by John/Area  of  Land owned by Sam

=2.17 x 104 square miles/ 5.34 x 103 square miles

=21,700 square miles /5,340 square miles

=4.064 times

Therefore  we say that John's owns an area of land  by 4.064 times Sam's land.

Answer: y=-2x-9

Step-by-step explanation:

If ANGL is a square, then NG and LG are adjacent sides.

Adjacent sides are perpendicular.  [Each angle is 90°]

The equation of line NG is [tex]Y=\dfrac12 X-6[/tex].

By comparing it to equation in slope intercept form y=mx+c ( where , m= slope , c=y-interecpt)

slope =[tex]\dfrac12[/tex]

Let slope of LG be n, then

[tex]n\times \dfrac{1}{2}=-1[/tex] [Product of slopes of two perpendicular line =-1]

[tex]\Rightarrow n=-2[/tex]

Equation of a line passes through (a,b) and have slope m is given by :-

[tex](y-b)=m(x-a)[/tex]

Equation of LG :

[tex](y-1)=-2(x-(-5))\\\\\Rightarrow\ y-1=-2x-10\\\\\Rightarrow\ y=-2x-9[/tex] [In intercept form]

Step-by-step explanation:

Given that:

The total cost of the fruit is $16.87

And Norman purchased 3.5 lb of his favorite mixture of dried fruits.

The cost of the fruit per pound can be calculated by dividing the total cost of fruit by the total amount of pounds of fruit purchased.

i.e.

The cost of the fruit per pound = $16.87/3.5

The cost of the fruit per pound = $4.82

Answer:

1782 cm³

Step-by-step explanation:

First, you measure the volume of the cuboid as a whole which is length x breadth x height, 9 x 12 x 18 = 1944 cm³. Then measure the volume occupied by the space, 3 x 3 x 18 since the hole runs along the entire length = 162 cm³.

Then you subtract the volume occupied by the hole from the volume of the cuboid in total, 1944 - 162 = 1782 cm³

f = 2

Step-by-step explanation:

Hope this helps you! :3

Answer:

f = 2

Step-by-step explanation:

2+1.25f = 10 - 2.75f

Add 2.75f to both sides

2 + 4f = 10

Subtract 2 on both sides

4f = 8

Divide by 4 on both sides to isolate the variable f

f = 8/4

f = 2
