To graph the equation 2x + 5y = 10, Zeplyn draws a line through the points (5, 0) and (0, What is the slope of the line represented by 2x + 5y = 10?
Answers
Answer: -2/5
Step-by-step explanation:
To find the slope, we set the function use y = mx + b forms.
2x + 5y = 10
5y = -2x + 10 Minus 2x in both side
y = -2/5x + 10/5 Divide 5 from both side
y = -2/5x + 2
In the y = mx + b, the m before variable x is always the slope, so -2/5 is the slope for 2x + 5y = 10.

How do matter and energy move through an ecosystem?
Answers
Step-by-step explanation:
How Matter Moves Through Ecosystems
Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher-level consumers when they eat lower-level consumers. When living things die, the cycle repeats.How Energy Moves Through Ecosystems
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during respiration in plants. The majority of the chemical energy stored in plants is transformed into other forms by an assortment of consumers, such as cows, rabbits, horses, sheep, caterpillars, and other insects eating plants.Fran can type 297 words in 5.5 minutes.

Variance Standard deviation
Answers
Answer:
[tex]Mean = 48.6364[/tex]
[tex]s^2 = 331.8545[/tex] -- Sample Variance
[tex]s = 18.2169[/tex] --- Sample Standard Deviation
Step-by-step explanation:
Given
[tex]n = 11[/tex]
[tex]Data: 24, 41 ,25 ,68 ,53 ,83 ,43 ,63 ,56 ,34 ,45[/tex]
Solving (a): The sample mean
[tex]Mean = \frac{\sum x}{n}[/tex]
So:
[tex]Mean = \frac{24 +41 +25 +68 +53 +83 +43 +63 +56 +34+ 45}{11}[/tex]
[tex]Mean = \frac{535}{11}[/tex]
[tex]Mean = 48.6364[/tex]
Solving (b): Sample variance (s^2)
This is calculated as:
[tex]s^2 = \frac{\sum (x - \bar x_i)^2}{n - 1}[/tex]
Where:
[tex]\bar x = 48.6364[/tex]
So:
[tex]s^2 = \frac{(24 -48.6364)^2 +(41 -48.6364)^2 +......................+( 45 -48.6364)^2}{11-1}[/tex]
[tex]s^2 = \frac{3318.54545456}{10}[/tex]
[tex]s^2 = 331.8545[/tex]
Solving (c): Sample Standard Deviation (s)
This is calculated as:
[tex]s = \sqrt {s^2[/tex]
[tex]s = \sqrt{331.8545[/tex]
[tex]s = 18.2169[/tex]

Answers
Answer:

What is a right angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.
In the given diagram,
The distance between observer and bird = 1.9 miles,
And the distance from observer to the ground = 1.2 miles.
Let the distance of bird from ground is h miles.
To find the distance of bird from ground,
Use Pythagoreans theorem,
(1.9)² = (1.2)² + h²
3.61 = 1.44 + h²
3.61 - 1.44 = h²
2.17 = h²
h = 1.473 miles
The distance of bird from the ground is 1.47 miles.

(-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent expression to 7x² + 2x - 5
(12x² + 6x - 5) - (5x² + 8x - 12) is equivalent expression to 7x² - 2x + 7
Step-by-step explanation:
✔️(3x² - 6x + 11) - (10x² - 4x + 6)
Open the bracket by applying the distributive property
3x² - 6x + 11 - 10x² + 4x - 6
Add like terms
-7x² - 2x + 5
Therefore:
(3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to expression -7x² - 2x + 5
✔️(-3x² - 5x - 3) - (-10x² - 7x + 2)
Apply distributive property
-3x² - 5x - 3 + 10x² + 7x - 2
Add like terms
7x² + 2x - 5
Therefore:
(-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent expression to 7x² + 2x - 5
✔️(12x² + 6x - 5) - (5x² + 8x - 12)

Solve the system using substitution.
X + 2y = -6
6x + 2y = 4
([?], [ ]
Answers
Answer:
Step-by-step explanation:
Rearrange x+2y=-6 to solve for x:
x = -2y-6
substitute -2y-6 for x into the second equation:
6x + 2y = 4
6(-2y-6) + 2y = 4
-12y-36 + 2y = 4
-10y = 40
y = -4
x = -2y-6 = 2
(x,y) = (2,-4)
The solution for the system of equations is (2,-4).
The given system of equations are x + 2y = -6-----(1) and 6x + 2y = 4-----(2).
How do solve systems of equations using the substitution method?To solve a system of equations using substitution:
Step 1: Isolate one of the two variables in one of the equations.Step 2: Substitute the expression that is equal to the isolated variable from Step 1 into the other equation. This should result in a linear equation with only one variable.Step 3: Solve the linear equation for the remaining variable.Step 4: Use the solution of Step 3 to calculate the value of the other variable in the system by using one of the original equations.Now, rearrange x+2y=-6 to solve for x:
So, x = -2y-6
Substitute -2y-6 for x into the second equation 6x + 2y = 4.
That is, 6(-2y-6) + 2y = 4
⇒-12y-36 + 2y = 4
⇒-10y = 40
⇒y = -4
By substituting y = -4 in x = -2y-6 we get x=2.
Therefore, the solution for the system of equations is (2,-4).
