Answer: To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect. The two lines intersect in (-3, -4) which is the solution to this system of equations.

What is quadrilateral?A figure consisting of four sides connected together and forming a total angle of 360 degrees is called a quadrilateral.
Given that:-
ABCD is a kite, so AC I DB and DE= EB.
AD = 4 cm BD = 4 cm and CD = 3 cm.
The side AC will be calculated as:-
Since AC is bisecting the line BD so BE = ED and BE = 2 cm and ED = 2 cm. WE have AD = 4 cm so we will calculate AE first by using the Pythagorean theorem.
AE² = AD² - ED²
AE² = 4² - 2²
AE² = 16 - 4 = 12
AE = √12 = 3.46 cm
Similarly, we will find the value of EC.
EC² = 3 ² - 2²
EC² = 9 - 4 = 5
EC = √5 =2.23
WE know that AC = AE + EC
AC = 3.46 + 2.23
AC = 5.69 cm
Therefore the length of the side AC will be equal to 5.69 cm

A population of mutant Venus fly trap plants are taking over an island in the South Pacific, capturing everything from insects to small rodents
Answers
The question is incomplete. The complete question is :
A population of mutant Venus fly trap plants are taking over an island in the South Pacific, capturing everything from insects to small rodents. When they were first discovered they covered 4 square kilometers. As the population grows, the plants spread and cover more land. Use the table to write an equation.
Solution :
It is given that:
Venus fly trap plant is capturing everything on its way from small insects to other small rodents.
When they were first discovered, it covered an area of 4 square kilometers. But as more population grew and as years passed by, they spread over large land and covered more land.
Now from the table, it is seen that :
It covered 4 km square when discovered.
Then it covered 6.68 km square in the first year.
It covered 11.16 km square in the second year.
It covered 18.63 km square in the third year.
It covered 31.11 km square in the fourth year.
Therefore the equation which represents the growth is given by :

Answers
Answer:
Always linear...
Decreases with successive trophic level
Answer:
Food chains are very important for the survival of most species. When only one element is removed from the food chain it can result in extinction of a species in some cases.An example of a simple food chain would be: A plant grows using the sun's energy and nutrients from the soil. A rabbit eats the plant. A fox eats the rabbit. The fox dies and decomposes into organisms that feed the soil.A producer, which is able to produce its own food, is also called an autotroph. Every species in the ecosystem relies on producers for their existence.A producer is able to covert inorganic compounds into organic compounds. Without this process life could not exist.A producer can use either solar energy or chemical energy to convert organisms into usable compounds.Because the sun is necessary for photosynthesis, life could not exist if the sun disappeared.Consumers can be carnivores (meat eater only), herbivore (plant eater only), omnivore (eats animals and plants), and a scavenger (eats dead animals).Examples of omnivores (plant and animal eaters) are bears (which eat fish, insects, honey, moose, and grass), turtles (which eat crayfish, earthworms, lettuce, and algae), squirrels (which eat seeds, fruit, eggs, and insects), and monkeys (which eat fruit, leaves, and frogs).Examples of carnivores (animal eaters) include hawks, snakes, foxes, and spiders.Examples of herbivores (plant eaters) include rabbits, moose, cows, groundhogs, and grasshoppers.Decomposers, which feed on dead animals, break down the organic compounds into simple nutrients that are returned to the soil. These are the simple nutrients that plants require to create organic compounds.It is estimated that there are more than 100,000 different decomposers in existence.Al-Jahiz was a 9th century scientist who is responsible for introducing the concept of food chains.The food web, which is a concept that expands on the food chain, was introduced in 1927 by Charles Elton.Food chains can be short, or they can be long, depending on how many consumers can be eaten before one dies and begins to decompose.If a food chain were to continue too long, the energy would become less and less and it would not be very valuable to the animal at the end.Step-by-step explanation:

What is the diameter of a circle go through
Answers
Answer:
The diameter of a circle passes through the center of the circle and has its endpoints on the circle itself. The diameter of any circle is two times the length of that circle's radius.
Step-by-step explanation:
To find the diameter of a circle, you need to know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.

Answer:
B. 9/40
Step-by-step explanation:
just got the answer
The value of the tanθ is 9/40 after applying the Pythagoras theorem option (C) 9/40 is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a trigonometric ratio:
As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
sinθ = 9/41
sin is the ratio of the side opposite to the hypotenuse.
From the Pythagoras theorem:
Adjacent side² = hypotenuse² - opposite²
Adjacent side² = 41² - 9²
Adjacent side = 40
tan is the ratio of the side opposite to the adjacent
tanθ = 9/40
Thus, the value of the tanθ is 9/40 after applying the Pythagoras theorem option (C) 9/40 is correct.

A function f(x) has x-intercepts of -3 and -5. What is the constant term in the function?
f(x) = x2 + 8x +
Answers
Answer:
15
Step-by-step explanation:
The x-intercepts -3 and -5 are also "roots" of the polynomial. The corresponding factors are (x + 3) and (x + 5). Multiply the constants together: 3*5 = 15. This is the desired constant term.
Note that your f(x) = x2 + 8x + should be written f(x) = x^2 + 8x + ... The " ^ " denotes exponentiation.
Check: Multiply (x + 3) and (x + 5) together and compare the result to the given polynomial with constant term 15:
f(x) = (x + 3)(x + 5) = x^2 + 3x + 5x + 15 = x^2 + 8x + 15. This matches!

Find 5 Rational Numbers Between 1 and 2 using (a+b/2) where a=1 and b=2.
Answers
Answer:
There are two ways to find the rational number between any two numbers. I will tell you an easy method to find it.
As we have to find 5 rational numbers between 1 & 2
Take 5 and add 1 to it i.e. 5+1= 6
Now take the first number and multiply and divide it by 6 i.e.
1x6/6 = 6/6
Also take the second number and multiply and divide it by 6 i.e.
2x6/6= 12/6
This is done to convert 1 & 2 into rational number i.e. in form of p/q
Now we have two numbers 6/6 and 12/6 so five rational numbers between them are
7/6, 8/6, 9/6, 10/6, 11/6
The values of these number you can check will be between 1 & 2. Actually between any two number there are infinite number of rational numbers.
