The line parallel to Line 1 which is given by the equation: −6y + 3x = 12 and passes through (−1, − 5) is written in slope intercept form as
\y = 0.5x - 4.5
How to write the equation of the line in slope intercept formA linear function consists of functions where the variables has exponents of 1. the relationship is expressed in the slope intercept form as below.
y = mx + c
definition of variable to suit the problem
y = output variable
m = slope
x = input variable
c = y intercept
The given equation is rewritten in slope intercept form as follows
−6y + 3x = 12
−6y = 12 - 3x
y = 1/2 x - 2
the slope is 1/2
equation of the line of slope = 1/2 passing through point (-1, -5) is calculated using the point slope formula which is
(y - y') = m(x - x')
(y + 5) = 1/2(x + 1)
y + 5 = 1/2 x + 1/2
y = 1/2 x + 1/2 - 5
y = 0.5x - 4.5

Can somebody please tell me how to Solve Systems by Elimination? I don't understand it at all and I'm staying up all night trying to figure it out. I especially don't understand the co-efficient part.
An example is:
2c+3d=12
5c-d=13
What would the answer be to that? Please provide an explanation!
Solving the example, hope it will help you with better understanding.
Given system:
2c + 3d = 125c - d = 13We need to eliminate one of the variables c or d. Let us eliminate d.
We see the first equation has 3d and the second equation has - d. The coefficients of d are 3 and - 1. If we multiply the second one by 3 it will become - 3, then if we add them up they will cancel, 3d - 3d = 0. By doing this we'll eliminate the variable d and left with variable c in the resulting equation.
Demonstrating how it works:
2c + 3d = 12, we leave it as is
5c - d = 13, we multiply all terms of this by 3, it becomes, 15c - 3d = 39
Now add up the two equations:
2c + 15c + 3d - 3d = 12 + 39, eliminated d17c = 51 solving for cc = 51/17c = 3Now we can find the value of d:
2c + 3d = 122*3 + 3d = 126 + 3d = 123d = 6d = 2Our solution is:
c = 3, d = 2The figure below is composed of square ABCD and equilateral triangle
Answer: 225°
Step-by-step explanation:
The correct option is D)
Refer Figure
Given:
ABCD is a square
ABP is an equilateral triangle
AB=BP=BC (△ABP is equilateral and AB and BC belong to a square, hence all are equal)
∠ABC=∠ABP+∠PBC=60°+∠PBC
90°−60°=∠PBC
∠PBC=30°
In △BPC
BP=BC
∠BPC=∠BCP= 2
180−∠PBC
( angles opposite to equal sides of a triangle are equal)
∠APC=∠APB+∠BPC=(60+75)°=135°
Hence, Reflex ∠APC=(360−135)°=225°

The tangent ratio of F by using the rule from trigonometry is 4/3
What is the trigonometry ratio?Trigonometric ratios are ratios that represent the length of a triangle's sides. In trigonometry, these ratios show how the ratio of a right triangle's sides to each angle. Sine, cosine, and tangent ratios are the fundamental trigonometric ratios.
The sine of the trigonometry ratio is sin θ = opposite/hypotenuse. The cosine of the trigonometry ratio is cos θ = adjacent/hypotenuse. The tangent of the trigonometry ratio is tan θ = opposite/adjacent. From the image given. The opposite side is the line facing the angle F;
Thus, the opposite side = 8, and the adjacent is the smallest side, which is 6.
Therefore, the tangent ratio for F is:
tan θ = 8/6
This can be reduced to 4/3
Therefore, we can conclude that the tangent ratio of F is 4/3.

What are supplementary angles ?
The angles are said to be in supplementary if and only if the sum of two angles is 180 degrees .
Angles 3 and 4 are supplementary.
The measure of angle 3 is
thirty-five more than one-fourth the measure of angle 4.
So,
∠3 + ∠4 = 180 degrees.
∠3 = 180-∠4 - equation 1
∠3 = 35 + (1/4 ) ∠4 - equation2
As equation 1 and 2 are equal
hence,
180-∠4 = 35 + (1/4) ∠4
180-35 = ∠4 + (1/4) ∠4
145 = ((1/4)+1) ∠4
145 = (5/4) ∠4
∠4 = 145 * 4 / 5
∠4 = 29*4
∠4 = 116
∠3 = 180-116
∠3 = 64
Hence the values of ∠4 and ∠3 are 116 degrees and 64 degrees respectively.

The sum of the two digits number is nine
If the sum of two digits t and u is t + u = 9, then the second equation is option 2: t = 1/2 u.
What is a digit?
In math, single integers called digits are used to represent values. To represent all mathematical values, the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are employed in various combinations and repetitions.
The first equation is as given t + u = 9
Second equation t = u/2 since the number in the tens position is one half of the one in the units. So if you divide u by two, you should have one t, as the equation states.
The second equation is t = (1/2)u => u = 2t
When we replace this in first equation we get -
t + 2t = 9
3t = 9
t = 9/3
t = 3
When we replace it again in the equation -
u = 2 t
= 2 · 3
= 6
The requested number is 36.
Therefore, the number is 36 and the second equation is t=u/2.

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas. It involves the study of variables, expressions, equations, and functions.
Let's solve for x:
3(4x - 10) = 2(3x - 30)
First, we can simplify both sides by distributing the coefficients:
12x - 30 = 6x - 60
Next, we'll move all the x terms to one side of the equation and the constants to the other side:
12x - 6x = -60 + 30
Simplifying further:
6x = -30

What is permutation?
An arrangement of items in a specific manner or sequence is referred to as a permutation. It is important to think about both the selection and the arrangement when dealing with permutation. Briefly put, permutations depend much on ordering. In other words, a permutation is a combination that is ordered.
We want to choose 7 objects without replacement from 11 distinct objects
So, since the order of the choices is relevant, we will use permutation.
Therefore,
⇒nPr = n! ÷ (n - r)!
⇒11P7 = 11! ÷ (11 - 7)!
⇒11P7 = 11! / 4!
⇒11P7 = (11 * 10* 9 * 8 * 7* 6 * 5)

the volum of the wood in a tree varries directly as height and the square of length
Answer:
The volume of wood in a tree varies directly with the height and the square of the length of the tree. This means that if we increase the height of the tree, the volume of wood in the tree will also increase, and if we increase the length of the tree, the volume of wood will increase by the square of that increase.
This relationship can be expressed mathematically as:
V = khl^2
Where V is the volume of wood in the tree, h is the height of the tree, l is the length of the tree, and k is a constant of proportionality.
This relationship is based on the assumption that the cross-sectional area of the tree remains constant, and that the volume of wood in the tree is directly proportional to the height and the square of the length of the tree.

Answer:
-4
Step-by-step explanation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}=\frac{0-(-8)}{0-2}=\frac{8}{-2}=-4[/tex]
The slope of the line that passes through the points (2, -8) and the origin is calculated using the formula m = rise/run, which gives -4.
Explanation:In this Mathematics problem, we are asked to find the slope of the line that passes through two points using the formula m = rise/run, where 'm' is the slope. The points provided are (2, -8) and the origin, which is (0, 0).
To find the slope (rise/run), we can subtract the y-values (rise) and the x-values (run) of the two points, respectively. So, the formula becomes: m = (-8 - 0) / (2 - 0) => m = -8/2 = -4.
Therefore, the slope of the line that passes through the points (2, -8) and the origin is -4.
