Which function has the greatest constant of variation? A x 8 9 10 11 y 20 22.5 25 27.5 B x 1 2 3 4 y 3.2 6.4 9.6 12.8 C On coordinate plane C, a line goes through points (0, 0) and (3, 1). D On coordinate plane D, a line goes through points (0, 0) and (1, 2).
Answer:
the answer is b
Step-by-step explanation:
edge 2020
The function with the greatest constant of variation is function B, x: 1, 2, 3, 4, y: 3.2, 6.4, 9.6, 12.8.
What is the equation?
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The constant of variation (k) is calculated as k = Δy/Δx for two points on a line.
For Function B, k = (6.4 - 3.2)/(2 - 1) = 3.2, which is the greatest constant of variation among all the functions.
For Function A, x: 8, 9, 10, 11, y: 20, 22.5, 25, 27.5, k = (22.5 - 20)/(9 - 8) = 1.25.
For Function C, on the coordinate plane C, a line goes through points (0, 0) and (3, 1), k = (1 - 0)/(3 - 0) = 1/3.
For Function D, on the coordinate plane D, a line goes through points (0, 0) and (1, 2), k = (2 - 0)/(1 - 0) = 2.

blThe mean height of the corn plants of variety A is 43.8 inches. Interpret the value of the mean in the
situation.
Answer:
The average inches of the height of the corn plants of variety A is 43.8 inches
Step-by-step explanation:
In mathematics or statistics, the mean refers to the average of numbers.
The mean is estimated by dividing sum of all the numbers by the count of the numbers.
For this question, the mean height of the corn plants of variety A of 43.8 inches is obtained as follows:
Sum of all the inches = 46 + 46 + 47 + 48 + 49 + 49 + 50 + 6 + 48 + 49 = 438 inches
Count of all the inches = 10
Mean = Sum of all the inches / Count of all the inches = 43.8 inches
The interpretation of this is that the average inches of the height of the corn plants of variety A is 43.8 inches.

alejandro william scored 13 goals last season. he scored 5 more goals this season than last season than last season. how many goals did he score this season
Answer:
18 goals this season.
Step-by-step explanation:
First, we must identify what the question is asking.
13 goals last season, 5 more this season.
How many this season?
Well, if he scored more this season, we know this is going to be an addition problem.
Since he scored 13 last season a 5 more this season, we must add 13 and 5.
13 + 5 = 18 :D
Answer:
18 goals this season
Step-by-step explanation:
Well we are trying to find the answer to this season.
If he scored more goals than last season (13), you will need to add.
13+5= 18

Answer:
Give M the statement of this question
∠A and \angle B∠B are complementary angles. If m\angle A=(8x+27)^{\circ}∠A=(8x+27)
∘
and m\angle B=(6x-21)^{\circ}∠B=(6x−21)
∘
, then find the measure of \angle B∠B.
Answer:
∠ B = 15°
Step-by-step explanation:
Complementary angles sum to 90° , that is
∠ A + ∠ B = 90 , substitute values
8x + 27 + 6x - 21 = 90
14x + 6 = 90 ( subtract 6 from both sides )
14x = 84 ( divide both sides by 14 )
x = 6
Thus
∠ B = 6x - 21 = 6(6) - 21 = 36 - 21 = 15°
Answer:
16
Step-by-step explanation:
(3x+9)+(6x+27)=
(3x+9)+(6x+27)=

Listen i know its dumb but-
solve for w
10 + w = -9
Answer:
w = -19
Explanation:
To solve this equation, subtract ten from both sides. This will isolate the variable (w) and allow us to find its value.
[tex]10 + w = -9\\(10 - 10) + w = (-9 - 10)\\w = (-9 - 10)\\w = -19[/tex]
If you would like to double check that the variable (w) does in fact equal negative nineteen, substitute the value of the variable in the equation and solve.
[tex]10 + w = -9\\10 + -19 = -9\\-19 = -19 [true][/tex]
Therefore, the value of w in the given equation is -19.

Answer:
I think it would be A
Step-by-step explanation:
you can take the square root of x^2 to make it x and then you would have to do that to the 10 as well. from there we know that the number can be either positive or negative so that would be the answer. you dont always have to put an exact number for these questions.
Answer:
a) [tex]\pm\sqrt{10}[/tex]
Step-by-step explanation:
[tex]x^2 = 10[/tex]
[tex]\sqrt{x^2} =\sqrt{10}[/tex]

What values of x and y satisfy the system of equations {y=3x+2y=3x−6? Enter your answer as an ordered pair, like this: (42, 53) If your answer includes one or more fractions, use the / symbol to separate numerators and denominators. For example, if your answer is (4253,6475), enter it like this: (42/53, 64/75) If there is no solution, enter "no"; if there are infinitely many solutions, enter "inf."
Answer:
No solutions / "no"
Step-by-step explanation:
y = 3x + 2
y = 3x - 6
Since both equations are equal to y, you can set them equal to each other.
3x + 2 = 3x - 6
subtract 3x from both sides
2 = -6
This equation is not true, therefore your answer is no solutions.
