What value of y would make {(-2, 18), (3, y), (6, 6), (-18, 2), (4, 9)} an inverse variation?
Answer:
The value of "y" the would make the ordered pairs an inverse variation is;
y = 12
Step-by-step explanation:
The given ordered pairs are;
{(-2, 18), (3, y), (6, 6), (-18, 2), (4, 9)}
When a pair of variables, "x" and "y", vary inversely to one another, as the value of one variable increases, the value of the other variable decreases
Mathematically, we have;
y ∝ 1/x
The above relation can be represented as an equation as follows;
y = k/x
Where;
k = The constant of proportionality
Therefore, k = y·x
From the given ordered, we have;
k = -2 × 18 = -36
k = 6 × 6 = 36
k = -18 × 2 = -36
k = 4 × 9 = 36
Therefore, the value of "k" is made constant as follows;
The inverse variation is y = k/(x × (-1)ⁿ)
Where;
n = The number of the term
Therefore, y = 36/(3 × (-1)²) = 12
y = 12
The given ordered pairs can therefore be written as follows;
{(-2, 18), (3, 12), (6, 6), (-18, 2), (4, 9)}.

In a community center 15 bottles are spaced evenly 12 cm apart from each other in a row for competition. What is the distance from the fourth bottles to the tenth bottles
Answer:
72cm
Step-by-step explanation:
From the 4th bottle to the 10th bottle there would be 6 gaps each of 12 cm as mentioned in the question.
Therefore, the total gap or distance between 4th and 10th bottles = 6*12 =
72cm
Given parallelogram JKLM, complete the following statements.
X=
Y=
m
m< L= Degrees
ML=
Answer: x= ?
y= 5
mK= 17
mL= 17
ML= 33
Step-by-step explanation:
i dont want to explain but i don’t know what x is i’m sure the rest are right
The value of x is; 20, the value of the y is 5 and the value of the angle K is; 43 degrees.
Given that;
Length of the line XL is 2y+23.
Length of the line Ml is 32-3y.
Length of the line JK is 6y-13.
What is Parallelogram?Parallelogram is a closed shaped quadrilateral in which the opposite sides are equal and parallel. Consecutive angles in a parallelogram are supplementary.
The sum of the consecutive angles is equal to the 180 degrees (supplementary).
Thus,
m∠M + m∠J = 180°
(6x + 17) + (2x + 3) = 180°
8x + 20 = 180°
8x = 160°
x = 20
So, m∠M = (2x + 3)°
= 2(20) + 3
= 43°
As the opposite sides of the parallelogram are equal. Thus;
(6y - 13) = 32 - 3y
6y + 3y = 32 - 13
9y = 45
y = 5
Now Opposite angles of a parallelogram are equal in measure thus,
m∠M = m∠K = 43°
Thus, the value of x = 20,
the value of the y = 5 and value of the angle K = 43 degrees.

which equation represents a linear function? y=4/x+1, y=2/3x -1/2
Answer:
y = 2/3x - 1/2
Step-by-step explanation:
y = 2/3x - 1/2 is a linear function. It contains a slope and a y-intercept and every x value will produce a unique y value.
y = 4/x + 1 is a rational function, as it contains a fraction.
Answer:
y = 2/3x - 1/2
Step-by-step explanation:
y = 2/3x - 1/2 is a linear function. It contains a slope and a y-intercept and every x value will produce a unique y value.
y = 4/x + 1 is a rational function, as it contains a fraction.

Enter a value for x that makes the equation -2x + 10 + 4x = 70 true
Answer:
x = 30
Step-by-step explanation:
- 2x + 10 + 4x = 70, that is
2x + 10 = 70 ( subtract 10 from both sides )
2x = 60 ( divide both sides by 2 )
x = 30

On a map, Roseville and smith town are 5 1/2 inches apart If the actual distance between the town is 16 1/2 miles, to what unit rate is the map drawn
Answer: The unit rate = 3 miles per inch.
Step-by-step explanation:
Given: Distance on map = [tex]5\dfrac12[/tex] inches [tex]=\dfrac{11}{2}[/tex] inches
Actual distance = [tex]16\dfrac12[/tex] miles [tex]=\dfrac{33}{2}[/tex] miles
That means 1 inch on map = [tex]\dfrac{\dfrac{33}{2}}{\dfrac{11}{2}}\ miles[/tex]
[tex]=\dfrac{33}{2}\ miles[/tex]
[tex]=3\ miles[/tex]
Hence, the unit rate = 3 miles per inch.

Find the value of x in 4:x::x:16
Given:
4:x::x:16
To find:
The value of x.
Solution:
We have,
4:x::x:16
It means, we have
4:x = x:16
It can be rewritten as
[tex]\dfrac{4}{x}=\dfrac{x}{16}[/tex]
On cross multiplication, we get
[tex]4\times 16=x\times x[/tex]
[tex]64=x^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{64}=x[/tex]
[tex]\pm 8=x[/tex]
Since ratio can be negative or positive, therefore, the value of x is either -8 or 8.

c = 49 cm, a = 41°. Find B in degrees. Round to 2 decimal places.
Answer:
49.03 degrees
Step-by-step explanation:
c = 49, [tex]\alpha[/tex] = 41
We can solve for [tex]\beta[/tex] if we first find b.
Remember: SOH CAH TOA
Cosine = Adj/Hypotenuse
So, Cos (41) = b/49
49 x (Cos 41) = b
49 x .755 = b
b = 36.99
sin [tex]\beta[/tex] = Opp/Hyp = b/49 = 36.99/49 = .755
β = inverse sin (.755) = 49.03° (Inverse sin is designated by sin⁻¹ on your calculator)
