choice c, slope is 3/1, y-int is -4

Answer 2

Answer:

C. f(x)=3x-4

Step-by-step explanation:

slope formula is (y2-y1)/(x2-x1)

(-1+4)/(-1-0)

3/1=3

The slope is going up and to the right so it is positive

is the function y= sin(x)/x even, odd or neither

Answers

the function is odd

The function y = sin(x) / x is an even function.

What is an even function?

Even Function - A true function f(x) is said to be an even function if the output value of f(-x) is the same as the f(x) for all values of x in the domain of f.

The equation should be stored in an even function:

f(-x) = f(x)

The function is given as,

y = sin(x) / x

Put x = -x, then we have

y = sin(-x) / (-x)

y = -sin(x) / (-x)

y = sin(x) / x

The function y = sin(x) / x is an even function.

More about the even function link is given below.

Anyone with the answers to unit 1 Geometry basics homework 5 angle relationships

Answers

Answer:

Step-by-step explanation:

1) x + 65 = 90

x = 90 -65

x = 25

2) x + 51 = 180 {Linear Pair}

x = 180 - 51

x = 129

3) y = 107 {Vertically opposite angles are equal}

x + 107 = 180 {linear pair}

x = 180 - 107

x = 73

z = x {Vertically opposite angles are equal}

z = 73

4) If sum of two angles is 180,, then they are called supplementary.

one angle = 13

It's supplement = 180 - 13

= 167

5) If sum of two angles is 90, then they are called complementary.

one angle = 38

It's complement = 90 - 38

= 52

6) ∠1 + ∠2 = 180

5x + 9 + 3x +11 = 180 {Combine like terms}

8x + 20 = 180

8x = 180 -20

8x = 160

x= 160/8

x = 20

∠1 = 5x + 9

= 5*20 +9

= 100+9

= 109

∠2 = 3x +11

= 3*20 +11

= 60 +11

= 71

7) Vertically opposite angles are equal

∠2 = ∠2 1

20x - 14 = 17x + 1

20x - 17x -14 = 1

3x - 14 = 1

3x =1 +14

3x = 15

x = 15/3

x = 5

∠2 = 20x - 14

= 20*5 - 14

= 100 - 14

= 86

8) ∠K + ∠L = 90

3x +3 + 10x - 4 = 90 {Combine like terms}

13x -1 = 90

13x = 90 + 1

x = 91/13

x = 7

∠K = 3x + 3

= 3*7 + 3

= 21 +3

= 24

∠L = 10x - 4

= 10*7 -4

= 70 - 4

= 66

The terms that does not describe polygon A’B’C’D should be considered as the option c. reflection.

What is reflection?

In terms of geometry, a reflection should be known as the flip, It should be considered as the mirror image of the shape. The image should reflect via the line that we called as the reflection line.

When it should be at reflection so each and every point in the figure should be equidistant with respect to the another figure.

Hence, The terms that does not describe polygon A’B’C’D should be considered as the option c. reflection.

Ye is riding home from a friend's house. After 5 minutes he is 4 miles from home, after 15 minutes Ye is 2 miles from home. Which equation models his distance from home y, in terms of minutes, x?

Answers

Answer:

[tex]y = -\frac{1}{5}x + 5[/tex]

Step-by-step explanation:

Given

[tex]5\ minutes = 4\ miles[/tex]

[tex]15\ minutes = 2\ miles[/tex]

Required

Determine the equation

y represents distance

x represents time

So, the given parameters can be modeled (x,y) as:

[tex](x_1,y_1) = (5,4)[/tex]

[tex](x_2,y_2) = (15,2)[/tex]

First, we need to determine the slope of the function.

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

[tex]m = \frac{2 - 4}{15 - 5}[/tex]

[tex]m = \frac{-2}{10}[/tex]

[tex]m = -\frac{1}{5}[/tex]

The equation can be determined using:

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

Where

[tex]m = -\frac{1}{5}[/tex]

[tex](x_1,y_1) = (5,4)[/tex]

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

becomes

[tex]y - 4 = \frac{-1}{5}(x - 5)[/tex]

Open bracket

[tex]y - 4 = -\frac{1}{5}x + 1[/tex]

Solve for y

[tex]y = -\frac{1}{5}x + 1 + 4[/tex]

[tex]y = -\frac{1}{5}x + 5[/tex]

Frank BaumChapter 12: The Search for the Wicked WitchThe Emerald City was soon left far behind. As they advanced the ground became rougher and hillier, for there were no farms nor houses in this country of the West, and the ground was untilled.In the afternoon the sun shone hot in their faces, for there were no trees to offer them shade; so that before night Dorothy and Toto and the Lion were tired, and lay down upon the grass and fell asleep, with the Woodman and the Scarecrow keeping watch.Now the Wicked Witch of the West had but one eye, yet that was as powerful as a telescope, and could see everywhere. So, as she sat in the door of her castle, she happened to look around and saw Dorothy lying asleep, with her friends all about her. They were a long distance off, but the Wicked Witch was angry to find them in her country; so she blew upon a silver whistle that hung around her neck.At once there came running to her from all directions a pack of great wolves. They had long legs and fierce eyes and sharp teeth."Go to those people," said the Witch, "and tear them to pieces.""Are you not going to make them your slaves?" asked the leader of the wolves."No," she answered, "one is of tin, and one of straw; one is a girl and another a Lion. None of them is fit to work, so you may tear them into small pieces.""Very well," said the wolf, and he dashed away at full speed, followed by the others.Read the passage on the left to answer the following questions:1) What inference can be made about the country of the West?A) The land is empty and barren.
