2 Determine whether the equation is a direct variation. If it is, state the constant of variation: 4y = 9x?
OYes, k= 9/4
O Yes, k = 4/9
O Yes, k = 9
O Not direct variation
Yes the the equation is following direct variation. Correct option is A, Yes, k = 4/9
What is Direct Variation?The change in one quantity as a result of the change in another is known as direct variation. This implies that if one quantity increases or decreases, the other must do the same.
Direct variation describes how one quantity directly affects the other when it varies. The precise reverse of this is called inverse variation. You will discover what direct and inverse variants are in this article, along with various cases that have been solved.
4y = 9x
standard equation for direct variation is y = kx
y = 9/4 x
On comparing the equation with standard equation,
k = 9/4
Hence, the equation is following direct variation

The cups of vinegar needed will be 1 1/3 cups.
How to calculate the value?From the information, the salad dressing recipe calls for 3/4 cup of olive oil for every 1/2 cup of vinegar.
Let the.cuos needed for the.olive.oio be represented by x.
Therefore, this will be:
1/2 / 3/4 = x/2
Cross multiply
0.75 × x = 2 × 1/2
0.75x = 1
x = 1/0.75
x = 1 1/3
Therefore the cups of vinegar needed will be 1 1/3 cups.

Two collinear points on a line are given in the table below:

2 1 (2,1)
Select the points that lie on the line. and the relationship between the coordinates x and y.

(4, 3)
(7,2)
4/8, 2/8
Answer:
(4,2) and ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex]) are lie on the line, and y = [tex]\frac{1}{2}[/tex] x , is showing the relationship of x and y coordinates of given line.Given that
The co-ordinates of line is (0,0) and (2,1).To find
The points that lie on the line, and The relationship between the coordinates x and y.So, according to the question
We have,
The X and Y co-ordinates of line (0,0) and (2,1).For finding any point that lie on line, first we have to find the slope of given line,
So, we know that
slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where,
x₁ = 0 and x₂ = 2
y₁ = 0 and y₂ = 1
Now, putting the values, we will get
(m) = [tex]\frac{1-0}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]
m = [tex]\frac{1}{2}[/tex]
We know that, the equation of line
y-y₁ = m(x- x₁ )
y-0 = [tex]\frac{1}{2}[/tex] (x- 0)
y = [tex]\frac{1}{2}[/tex] x -------------(1)
{ this equation (1) is showing a relationship the coordinates x and y }
For finding which point is lie in that line, this point must be prove that equation (1).
Now, let's check the points
For point (4,2)
y = [tex]\frac{1}{2}[/tex] x -------------(1)
2 = [tex]\frac{1}{2}[/tex] × 4
2 = 2
So, point (4,2) lie in this line.
For point (4,3)
y = [tex]\frac{1}{2}[/tex] x -------------(1)
3 = [tex]\frac{1}{2}[/tex] × 4
3 ≠ 2
So, point (4,3) not lie in this line.
For point (7,2)
y = [tex]\frac{1}{2}[/tex] x -------------(1)
2 = [tex]\frac{1}{2}[/tex] × 7
2 ≠ [tex]\frac{7}{2}[/tex]
So, point (7,2) not lie in this line.
For point ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex])
y = [tex]\frac{1}{2}[/tex] x -------------(1)
[tex]\frac{2}{8}[/tex] = [tex]\frac{1}{2}[/tex] × [tex]\frac{4}{8}[/tex]
[tex]\frac{2}{8}[/tex] = [tex]\frac{2}{8}[/tex]
So, point ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex]) lie in this line.
(4,2) and ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex]) are lie on the line, and y = [tex]\frac{1}{2}[/tex] x , is showing the relationship of x and y coordinates of given line.

A square acre of land is 5,280 square yards.
Between which two integers is the length of one side?
between 17 and 18 yards
between 72 and 75 yards
between 24 and 243 yards
between 1,320 and 1,321 yards
By factor decomposition, area of a square and power and root properties, the length of the side is between 72 yards and 76 yards. (Correct choice: B)
What integers are the limits between the length of an equivalent square side of a given area?
The area of a triangle is equal to the square of its side length and the area of land is a composite number, that is, a product of prime numbers. By factor decomposition, the equivalent form of 5,280 square yards is:
5,280 = 2⁵ × 3 × 5 × 11
Then, the equivalent side is equal to the square product of the product:
x = √(2⁵ × 3 × 5 × 11)
x = √(2⁴) × √(2 × 3 × 5 × 11)
x = 2² × √(2 × 3 × 5 × 11)
x = 4√330
As for √330 is between √324 = 18 and √361 = 19, then the length of the side is between 72 yards and 76 yards.

Using proportions, it is found that:
The value of A is of 10.The value of B is of 35.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
In the first row of the table, we are given the scale factors of 1 and 1.25. From the second row, we have that the width for a scale of 1 is of 8 inches, and for a scale of 1.25 is of A, hence:
A = 1.25 x 8 = 10.
For the third row, we have that the scale of 1 is of 28 inches, while the scale of 1.25 is of B, hence:
