x= 3

Step-by-step explanation:

1. -5(3) + 2 = -13      

2. -15 + 2 = -13         A positive times a negative will always equal a negative

3. -13 = -13         Whenever you add anything to a negative number, the                    

                           number becomes smaller

Answer: 2x-9y=1

Step-by-step explanation:

(this is how i found it don't know if this is how you learned it though)

Subtract 20 from both sides of -3x-8y=20, so that it becomes -3x-8y-20

Subtract 19 from both sides of -5x+y=19, so you get -5x+y-19

Subtract like terms from both equations (-3x-8y-20)-(-5x+y-19), which gives you 2x-9y-1

-3--5=2, -8-1=-9, -20--19=-1

Add 1 to both sides and you get 2x-9y=1

the prices of stock A at 9am was $12.18 since then the price has been increasing at the rate of $0.06 each hour. At noon the price of stock B was $12.68. It begins to descrease at the rate of $0.09 per hour. If the 2 rates continue in how many hours will the prices of the two stocks be the same?

Answers

Answer:

3.33hours

Step-by-step explanation:

Where the number of hours = h

the prices of stock A at 9am was $12.18 since then the price has been increasing at the rate of $0.06 each hour.

The Algebraic expression =

$12.18 + $0.06 × h

12.18 + 0.06h

At noon the price of stock B was $12.68. It begins to descrease at the rate of $0.09 per hour.

$12.68 - $0.09×h

12.68 - 0.09h

If the 2 rates continue in how many hours will the prices of the two stocks be the same?

Stock A = Stock B

12.18 + 0.06h = 12.68 - 0.09h

Collect like terms

0.06h + 0.09h = 12.68 - 12.18

0.15h = 0.5

h = 0.5/0.15

h = 3.3333333333 hours

h = 3.33hours

When a 49 pound weight is attached to a spring, the spring
stretches 7 inches. Assume that the length of the spring y varies directly
with the weight attached x. Write and solve a direct variation equation to
find the length of the spring when a 63 pound weight is attached.

Answers

im not for sure but I think the answer is 9! my reasoning is below,,

Step-by-step explanation:

[tex] \frac{49}{7} = \frac{63}{x} [/tex]

do the crossing method and it would result in this

(49×x) = (63×7)

after simplifying both sides

49x = 441

divide both sides by 49 and the result will be

x = 9 !!

4. Which of the following could be the areas of the three squares shown?

Answers

Answer:

Option (A)

Step-by-step explanation:

Three squares shown in the figure are formed on the sides of the given right triangle.

By Pythagoras theorem,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

Area of the square on the hypotenuse = Area of the square on the leg 1 + Area of the square on leg 2

Option (A).

95 = 40 + 55

True.

Option (B).

45 ≠ 35 + 25

False.

Option (C).

100 ≠ 10 + 10

False.

Option (D).

1200 ≠ 40 + 30

False

Therefore, Option (A) shows the areas of three squares.

Using the diagram below, what is the horizontal distance between the control tower and the plane?

Answers

Answer:

x = 664.093 m

Step-by-step explanation:

tan∅ = opposite over adjacent

Since we are trying to find the horizontal distance, that means we are dealing with the bottom length and not the hypotenuse (the diagonal length):

Our theta (∅) = 52°

Our opposite = 850 m

Our adjacent = x m

tan52° = 850/x

xtan52° = 850

x = 850/tan52°

x = 664.093 m

An excerpt from The Wonderful Wizard of OzL. 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.
