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

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

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 !!

What is the solution for the equation 6x - 8 = 4x? x =

Answers

Answer:

x = 4

Step-by-step explanation:

6x - 8 = 4x

subtract 4x from both sides of the equation

6x - 4x -8 = 4x - 4x

2x - 8 = 0

add 8 to both sides of the equation

2x - 8 + 8 = 0 + 8

2x = 8

divide both sides of the equation by 2

2x/2 = 8/2

x = 4

Answer:

x = 4.

Step-by-step explanation:

6x - 8 = 4x

6x - 4x - 8 = 0

6x - 4x = 8

2x = 8

x = 4.
