The corresponding equation of the proportional relationship will be;
⇒ y = - 1/4x
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
The graph of a proportional relationship contains the point (-12, 3).
Now,
Let the equation of the proportion is,
⇒ y = kx
Where, 'k' is constant of proportion.
Since, The graph of a proportional relationship contains the point (-12, 3).
Hence, Substitute x = 0 12 and y = 3 in above equation we get;
⇒ 3 = k × - 12
⇒ 3 / (-12) = k
⇒ k = - 1/4
Thus, The equation of the proportion is,

Bro can someone please help me on these three questions I’ve been trying to get help on these questions for like the past 30 minutes please help me
Answer:
Step-by-step explanation:
1). By applying cosine rule in the given triangle,
cos(x°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(x°) = [tex]\frac{6}{8}[/tex]
x = [tex]\text{cos}^{-1}(\frac{3}{4} )[/tex]
x = 41.41°
2). By applying cosine rule in the given triangle,
cos(x°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(x°) = [tex]\frac{4}{5}[/tex]
x = [tex]\text{cos}^{-1}(0.8)[/tex]
x = 36.87°
3). By applying cosine rule in the given triangle,
cos(x°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(x°) = [tex]\frac{51}{85}[/tex]
x = [tex]\text{cos}^{-1}(0.6)[/tex]

Answer:
x = 46, y = 67
Step-by-step explanation:
x = ∠ AEC = 46 ( alternate angles )
Since Δ ACE is isosceles then the base angles are congruent, then
y = [tex]\frac{180-46}{2}[/tex] = [tex]\frac{134}{2}[/tex] = 67
Answer:
x=46° and y=67°
Step-by-step explanation:
triangle ACE is isosceles, meaning <A=<B=y
any triangle is add up to 180. <A+<B+<C=180
y+y+46=180
2y=180-46
2y=134
divide both sides by 2
y=134/2
y=67°
for angle x°
since AB is parallel to CD,hence
<AEC=<ECD
x=46°
Find the theoretical probability that a 12-month calendar is turned to the month of May or the month of June. Write your answer as a fraction in simplest form.
Probability that the calendar turned to month of May or June is 1/6.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Total number of months = 12
Suppose that a calendar is turned.
Probability that the calendar turned to month of May = 1/12
Probability that the calendar turned to month of June = 1/12
Probability that the calendar turned to month of May or June = 1/12 + 1/12
= 2/12
= 1/6
Hence the probability that the calendar turned to month of May or June is 1/6.

DEFG is a square with vertices at D(1, 1), E(1,6), F(6, 6), and G(6, 1). DEFG is reflected in the line x = 1. Find the coordinates of
D',E,F, and G'.
By considering the reflection, the coordinates of the reflected square D'E'F'G' are:
D'(0,1) , E'(0,6), F'(5,6) and G'(5,1)
What is square?A square is a two-dimensional geometric shape that has four equal sides and four right angles. It is a type of rectangle, but with all sides equal. The opposite sides of a square are parallel and of equal length. A square can be defined by its side length or by the coordinates of its vertices.
What is reflection?Reflection is a type of transformation in geometry in which a shape is flipped over a given line, called the line of reflection. The image that is created is a mirror image of the original shape. The line of reflection can be a horizontal line, a vertical line, or any line that is not parallel to the axes. Reflecting a shape over a line involves taking the coordinates of each point of the shape and applying a specific rule (such as multiplying or adding a constant) to the x or y coordinate, depending on the line of reflection. This rule is often simple and easy to apply, such as reflecting over x = 1. The reflected shape will be in the same plane as the original shape but with a different orientation or position.
When a square is reflected in the line x=1, each of the points on the square will have their x-coordinate replaced by 1 subtracted from their original x-coordinate.
The coordinates of the reflected square D'E'F'G' can be found by applying this rule to the original coordinates of square DEFG:
D(1,1) => D'(1-1,1) => D'(0,1)
E(1,6) => E'(1-1,6) => E'(0,6)
F(6,6) => F'(6-1,6) => F'(5,6)
G(6,1) => G'(6-1,1) => G'(5,1)
So the coordinates of the reflected square D'E'F'G' are:
D'(0,1) , E'(0,6), F'(5,6) and G'(5,1)

What is the solution to this system of linear equations 2x 3y equals 3?
The solution to this system of linear equations is x = 3, y = 2.
2x - 3y = 3
2x = 3 + 3y
2x = 3y + 3
x = (3y + 3) / 2
x = 3/2 + 3/2y
x = 3, y = 2
This system of linear equations features two unknown variables, x and y. The equation 2x - 3y = 3 can be rearranged into 2x = 3y + 3. This equation can then be solved for x by dividing both sides by 2, resulting in x = 3y + 3/2. Since 3y + 3/2 must equal 3, this means that y must equal 2. Substituting 2 for y in the original equation yields 2x = 3 + 3(2), or 2x = 9. Dividing both sides by 2 yields x = 9/2, or x = 3. Therefore, the solution to this system of linear equations is x = 3 and y = 2.
