Answer:

  no real solutions; k = ±i(2/3)√15

Step-by-step explanation:

If k is one of the roots, then substituting it for x will satisfy the equation:

  k -4k -20/k = 0

Multiplying by k gives ...

  -3k^2 -20 = 0

  k^2 = -20/3 = -6 2/3

There are no real values of k such that this is true.

__

If we allow k to be imaginary, then ...

  k = ±i√(20/3) = ±i(2/3)√15

Possible imaginary values of k are ±(2/3)√15.

Answer:

-x^5 + 7x⁴ + 8x² - 9x - 5

Step-by-step explanation:

For the question given:

Rocks traded, sold or given away are denoted by negative values, '-' while rocks bought or purchased are diniywd as positive, '+'

Starting = 8x² ;

Purchase = + 7x⁴ ;

Trades = - x^5

Gives away = - 9x

Sells = - 5

The number of rocks Emily now has :

8x² + 7x⁴ - x^5 - 9x - 5

In standard form:

Arrange in order of power :

-x^5 + 7x⁴ + 8x² - 9x - 5

Answer:

If you wanted to simplify the equation:

9y - 30 = 6

If you wanted to solve for y:

y = 4

Step-by-step explanation:

3(3y - 10) = 6

9y - 30 = 6

Add 30 to both sides of the equation:

9y - 30 + 30 = 6 + 30

Simplify:

9y = 6 + 30

9y = 36

Divide both sides of the equation by 9:

9y ÷ 9 = 36 ÷ 9

Cancel terms that are in both the numerator and denominator:

y = 36 ÷ 9

y = 4

Answer:

1/2x-1

Step-by-step explanation:

-3-(-4)/-4-(-6)

1/2 slope

y-(-4)=1/2(x-(-6)

y+4=1/2(x+6)

y+4=1/2x+3

y=1/2x+3-4

y=1/2x-1

Using the equation y = abx , substitute both of your given points into that equation.

2 = ab2 and 4 = ab3 Solve each equation for a.

2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3

Cross multiply: 2b3 = 4b2 Divide both sides by b2

2b = 4 a = 2/4 = 1/2

b = 2

y = 1 (2)x

Answer:

x=10

Step-by-step explanation:

Well know that the 6x+1 angle plus the 29 degree angle are eqail to 90 degrees becasue that red square means that that whole angle is equal to 90 degrees. Now we can make a equation to represent this:

6x+1+29=90

6x+1=61

6x=60

X=10!

Answer:

This will be your answer. I hope this helps, good luck! :)

Yes, that is a correct statement.

But im left wondering what is the darn question

Answer:

no. they are not. add up the angles on each triangle to find x, if the angles are not exactly the same, then they are not similar

Answer:

13.8 ounces of salt

Step-by-step explanation:

A restaurant small salt shakers contains 0.6 ounces of salt. The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?

Step 1

Note that:

1 shaker = 0.6 ounces of salt

8 shakers = x

Cross Multiply

x = 8 × 0.6 ounces of salt

x = 4.8 ounces of salt

Step 2

The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?

This is calculated as:

18.6 ounces of salt - 4.8 ounces of salt

= 13.8 ounces of salt

Answer:

3 minutes; 27 minutes; 30 minutes

Step-by-step explanation:

Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.

Therefore,

[tex]x + 9x + 10x = 1 \: hour \\ \\ 20x = 60 \: minutes \\ \\ x = \frac{60 \: minutes}{3} \\ \\ x = 3 \: minutes \\ \\ 9x = 9 \times 3 = 27 \: minutes \\ \\ 10x = 10 \times 3 = 30 \: minutes[/tex]

Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:

3 minutes; 27 minutes; 30 minutes

Answer:

The jumping dolphin --  changes

The flying seagull -- same

The octopus --  same

Step-by-step explanation:

The distance of the Albatross from the sea surface when compared to the vertical distance from the eyes of the :

The jumping dolphin :

As the dolphin jumps out from the sea, the vertical distance of the albatross from the surface seems to be decreasing and then increasing as seen by the jumping dolphin.

The flying seagull :

The distance of the albatross is at the same height as seen by the seagull since it is flying at the same level, i.e. at the level of the sea surface

The octopus :

The octopus remains at the same depth below the water surface. So the distance of the albatross for the octopus remains the same at 5 m above the ocean surface.

Answer:

274 long sleeved shirts

Step-by-step explanation:

Deal Finder is sorting its production supply of long-sleeve shirts. They have 1,089 long-sleeve shirts. The first 266 are donated.

The amount of long sleeved shirt left after donation is calculated as:

1089 long sleeved shirts - 266 long sleeved shirts

= 823 long sleeved shirts left.

The rest are split up to be shipped to 3 stores. What fraction represents how many long-sleeve shirts each store will receive?

The amount of long sleeved shirts each store would receive is calculated as:

823 long sleeved shirts /3 stores

= 274 2/3 long sleeved shirts

A shirt is a whole number 1 and can't be in Fraction.

Therefore, each store would receive 274 long sleeved shirts

You will pay $450 for a item with original price of $600 when discounted 25%. In this example, if you buy an item at $600 with 25% discount, you will pay 600 - 150 = 450 dollars.
