Answer:

the answer for this problem is (x,y)=(0,9)

Answer:

y = 9

x = 0

Step-by-step explanation:

5x + 2y = 18

-5x + 5y = 45 add two equations up

5x + 2y -5x + 5y = 18 + 45 add like terms (note that, 5x will eliminate -5x)

7y = 63 divide both sides by 7

y = 9 to find the value of x we can use this information

5x + 2y = 18 replace y with 9

5x + 2*9 = 18

5x + 18 = 18 subtract 18 from both sides

5x = 0 and x = 0

Essentially, what we're looking at here are two alternate interior angles.

Wait. What? Alternate interior angles?

It sounds like some super fancy math jargon, but it's a fairly simple concept that I'll try my best to explain. First, let's look at lines L and M as two parallel lines, meaning that these two are lines with equal slopes, and will never intersect. See that line that goes in between the parallel lines L and M? That's called a transversal. It's basically a line that goes through two parallel lines.

Now we know that there's a transversal going through the parallel lines. So what? Well, there's a couple of special attributes to transversals. See the two angles, 7x-7 and 4x+14? As you can tell, these two angles alternate in the interior space between the transversal and the parallel lines.

Alternate interior angles are equal. There's a way to prove that they're equal, but I won't bore you with the specifics since that's not what the question's asking.

If the angles need to be equal for lines L and M to be parallel, we can make an equation that'll solve for x:

7x - 7 = 4x + 14

Subtract 4x from both sides:

7x - 4 x - 7 = 4x - 4x + 14

3x - 7 = 14

Add 7 to both sides:

3x - 7 + 7 = 14 + 7

3x = 21

Divide both sides by 3 to completely isolate x:

[tex]\frac{3x}{3}[/tex] = [tex]\frac{21}{3}[/tex]

x = 7

And that's our answer! If you need me to explain anything any further, just ask!

. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

Answer:

13

Step-by-step explanation:

The mean of the data is also known as the average. To find the mean/average, add up all the data and divide it by the number of inputs recorded.

9 + 16 + 13 + 14 + 10 + 16 + 17 + 9 = 104

There are 8 terms.

104 / 8 = 13

The mean is 13.

Step-by-step explanation:

Here only Fungi is an example of decomposer.

Rabbits and lions are examples of consumers.

Trees are an example of producers.

The following list defines and provides examples of the feeding (trophic) levels that comprise food webs:

Producer: organism on the food chain that can produce its own energy and nutrients. Examples: grasses, Jackalberry tree, Acacia tree

Primary consumer/herbivore: organism that eats mainly plants. Examples: cows, impalas, warthogs, zebras

Secondary consumer/carnivore: organism that eats meat. Examples: leopard, lion

Omnivore: organism that eats a variety of organisms, including plants, animals, and fungi. Examples: humans, aardvarks

Decomposer/detritivores: organisms that break down dead plant and animal material and waste and release it as energy and nutrients in the ecosystem. Examples: bacteria, fungi, termites

Scavenger: animal that eats dead or rotting animal flesh. Examples: vultures, hyenas

Insectivore: organism that mostly eats insects. Example: Red-billed oxpecker

Answer:

C. Fungi

B. Lions

Step-by-step explanation:

C. fungi are called decomposers because they break down the dead and decaying organic matter into simpler substances such as carbon dioxide, water, simple sugars, and mineral salts and provide the nutrients back to the soil

B. A decomposer is a living thing that gets energy by breaking down dead plants and animals, lions eat other animals to get energy.

Answer:

61.57 ft

Step-by-step explanation:

Look at the picture. You need to find the base value.

so we can sue the cosine formula here.

cos x° = adjacent / hypotaneous

cos 52 ° = adj / 100

adjacent = 100 cos 52°

               =61.57 ft

Answer:

the man is 61.6 ft away from the spot directly under the kite.

Step-by-step explanation:

in order to find the bottom length which is b we need to First find the height of this right angle triangle.

to find the height we need to use sin:

sin 52° = X/100

sin 52° * 100 = h

h= 78.8 ft

next we can find b which is the base of the triangle.

a^2+b^2=c^2

100^2 +b^2 = 78.8^2

100^2 -78.8^2 = b^2

b^2= 3790.56

b= √3790.56

b= 61.6 ft

therefore the man is 61.6 ft away from the spot directly under the kite.

Answer:

The relationship between these two sequences is it always doubles.  When we look at each sequence, 1, 2, 3, 4, 5, each number is multiplied by 2 to create the other sequence.

1 x 2 = 2.

2 x 2 = 4.

3 x 2 = 6.

4 x 2 = 8.

5 x 2 = 10.

When we arrange these numbers, 2, 4, 6, 8, 10, this is the exact sequence as before.  Therefore, this is the relationship.

Answer: 2, 4, 6, 8, 10,                           <                                |

                                                                                               |

Step-by-step explanation:                                                    |                                if you just  arange the numbers to 1 x 2 = 2                         |

                                                          2 x 2 = 4                       |

                                                          2 x 3 = 6                       |

  and then so on and so on you would get this answerer. |

Step-by-step explanation:

A invested 450

B invested 150

C invested 600

total investment was 1200

share of A is 450/1200 = .375

share of B is 150/1200 = .125

share of C is 600/1200 = .5

C received a profit of 24.70.

that would be .5 of the total profit.

if we let x = total profit, we get .5 * x = 24.70

solve for x to get x = 24.70 / .5 = 49.40

A share of total profit = .375 * 49.4 = 18.525

B share of total profit = .125 * 49.4 = 6.175

C share of total profit .5 * 49.4 = 24.7

total profit = 49.4 as we had calculated earlier.

Answer:

Below in bold.

Step-by-step explanation:

Degrees = radians * 180/π.

6. 3.8 radians = 3.8 * 180 / π

    = 217.7 degrees to nearest hundredth.

8. 5π/4 radians = 5π/4 * 180/π

     =  5*180/4

     =  225 degrees.

Answer:

The correct answer is [tex]11.45 cm. ^2[/tex]

Step-by-step explanation:

I just got it correct.

The approximate area of the shaded sector in the circle shown is,

⇒ 11.45 cm²

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

A circle is shown in figure with diameter 5.4 cm.

Hence, Radius of circle = 5.4 / 2 = 2.7 cm

Since, Area of circle = πr²

Hence, We get;

Area of circle = πr²

Area of circle = 3.14 × 2.7²

Area of circle = 22.89 cm²

Thus, Area of shaded region of the circle is,

⇒ 22.89 cm²

⇒ 22.89/2 cm²

⇒ 11.45 cm²

Thus, The approximate area of the shaded sector in the circle shown is,

⇒ 11.45 cm²

Answer: 15000 millimeters

Step-by-step explanation:

Since David David made a batch of 5 liters of blue liquid everyday. The number of liters that'll be made for 3 days will be:

= 5 liters × 3

= 15 liters

We should note that 1000 millimeters = 1 liter. Therefore, 15 liters will be converted to millimeters which will be:

= 15 × 1000

= 15000 millimeters
