Show that x²-3x-18=0
thanks)
Answer:
shown below
Step-by-step explanation:
we know right triangle formula that a² + b² = c²
where a is opposite, b is adjacent and c is hypotenuse
so, here a = (x + 6) , b = (x -1) , c = (2x + 1)
(x + 6)² + (x -1 )² = (2x + 1)² ............simplify
x²+12x+36 + x² -2x +1 = 4x² + 4x +1 ...............collect terms
2x² + 10x+ 37 = 4x² + 4x +1 ...............add them
-2x² + 6x + 36 = 0 ................bring them to one side and subtract and add
-2(x²-3x-18) = 0 .........take -2 as coefficient
x²-3x-18 = 0 ...........our final result
Therefore shown that x²-3x-18 = 0
Hey there mate ;),
Let's crack this question now!
Given: x²-3x-18=0
So,
\((2x + 1)^{2} = (x + 6)^{2} + (x - 1)^{2} \)
\( = > 4 {x}^{2} + 4x + 1 = {x}^{2} + 12x + 36 + {x}^{2} - 2x + 1\)
\( = > 4 {x}^{2} + 4x + 1 = 2 {x}^{2} + 10x + 37\)
\( = > 4 {x}^{2} - 2 {x}^{2} + 4x - 10x + 1 - 37 = 0\)
\( = > 2 {x}^{2} - 6x - 36 = 0\)
Now, by taking 2 as common factor, we get:-
\( = > {x}^{2} - 3x - 18 = 0\)

The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.
*look at the image I attached for a better explanation
By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation
\(?^2+6^2 = 10^2\\?^2 + 36 = 100\\?^2 = 64\\? = 8\)
Thus the missing side length is 8 cm

What is the meaning of "the cancellation laws"?
Each step of this theorem is proved below.
Given that,
S is finite,
Now enumerate all of its elements as x₁, x₂,..., x\(_{n}\).
According to the cancellation rule,
This product is independent of the order of the factors.
As a result, we can define the identity element e as this product.
It is simple to demonstrate that e meets the criteria of an identity element.
Now, let's show that every element of S has an inverse.
Let a be any element of S. Consider the set {a, a, a, ...}.
Since S is finite,
There exist positive integers m and n such that
am = an for some m > n.
By the cancellation law,
We can cancel a power of a from both sides to get a\({(m-n)}\) = e.
This means that a has an inverse, and we can conclude that S is a group.
Consider the set of all positive integers under addition, except 1, as an example of an infinite semigroup in which the cancellation laws hold but which is not a group.
This set clearly meets the cancellation laws, but it does not have an inverse for every element, because the inverse of 2, for example, is not an integer.
As a result, this is not a group.

What is 3/4 of 16 help
Answer:

3/4 of 16 would be 1/4 of 16 times 3.
So 1/4 of 16 is 4, and 4 x 3 = 12.
y=-0.024x^2+0.0791x+4.873
The equation y = \(-0.024x^2\) + 0.0791x + 4.873 represents a quadratic function with a downward-opening parabol
The given expression is a quadratic equation in the form y = -0.024x^2 + 0.0791x + 4.873. Let's analyze its components and characteristics.
The equation represents a quadratic function, where x is the independent variable and y is the dependent variable. The coefficients in front of each term determine the shape, position, and direction of the graph.
The term with the highest power of x is -0.024x^2, which indicates a downward-opening parabola. The coefficient -0.024 determines the steepness of the curve. A negative coefficient means the parabola is concave down.
The term 0.0791x is the linear term and determines the slope of the line. A positive coefficient indicates an upward or positive slope. It affects the overall direction and position of the graph.
The constant term 4.873 is the y-intercept. It indicates the point at which the graph intersects the y-axis when x = 0.
To analyze the graph of the quadratic equation further, we can calculate the vertex. The x-coordinate of the vertex can be found using the formula x = -b/(2a), where a and b are the coefficients of x^2 and x, respectively. In this case, a = -0.024 and b = 0.0791. Substituting these values into the formula, we have x = -0.0791 / (2 * -0.024) ≈ 1.643. By substituting this x-coordinate into the equation, we can find the y-coordinate of the vertex.
Overall, the equation y =\(-0.024x^2 + 0.0791x\) + 4.873 represents a quadratic function with a downward-opening parabola. The specific properties, such as the vertex and other key points, can be determined by further calculations and analysis of the equation.

Answer:
The answers are:x = ±7/4x = ±3/2x = ±11/8
yww:)
Answer:
Option A, \(x =\) ± \(11/8\)
Step-by-step explanation:
Step 1: Add 144 to both sides
\(64x^2 - 144 = -23\)
\(64x^2 - 144 + 144 = -23 + 144\)
\(64x^2 = 121\)
Step 2: Divide both sides by 64
\(\frac{64x^2}{64} = \frac{121}{64}\)
\(x^2 = 1.890625\)
Step 3: Square root both sides
\(\sqrt{x^2} = \sqrt{1.890625}\)
\(x =\) ± \(1.375\)
\(x =\) ± \(11/8\)

How to determine the transformationFrom the question, we have the following parameters that can be used in our computation:
y = x
Shift left 2 units
To shift the equation y = x to the left by 2 units, we can replace x with (x + 2) in the equation.
i.e. (x. y) = (x + 2, y)
So, we have the new equation to be y = x + 2

\(Width = x + 4\)
Step-by-step explanation:
Given
Shape: Rectangle
\(Area = x^2 + 11x + 28\)
\(Length = x + 7\)
Required
Determine the width
For a rectangle:
\(Area = Length * Width\)
Substitute values for Length and Area

Factorize the expression on the left hand side
\(x^2 + 7x + 4x + 28 = (x + 7) * Width\)
\(x(x + 7) + 4(x + 7) = (x + 7) * Width\)
\((x + 7)(x + 4) = (x + 7) * Width\)

2. infinitely many solutions
3. x = 6 y= -7
4.no solution
5. x = -3 y = -17
6. x= 3 y = 7
Step-by-step explanation:
1) y=x-1
7x+6y= -19
6y= -19 -7x
y= (-7x-19)/6
since x-1 and (-7x-19)/6 are both equal to y they are equal to each other
this is how to get x
x-1 = (-7x-19)/6
6x-6 = -7x-19
13x = -13
x = -1
now put back -1 in the equation to get y
y=x-1
y = -1 -1
y= -2
2)-10x+2y=-12
y=5x-6
2y= -12 + 10x
y= -6 + 5x
y = 5x - 6
5x-6 = 5x - 6

((when something is equal to just one answer its one solution)
3) y= -4x+17
y=x-13
-4x+17 = x-13
30 = 5x
x = 6
y=x-13
y=6-13
y= -7
4) -3x-15y=8
x+5y=5
-3x-15y=8 -> y = -1/15(3x-8)
5y=5-x -> y= 1/5 (5-x)
-1/15(3x-8) = 1/5 (5-x)
-x-8/3 = 5-x
0 = 23/3
(when something is not equal to something its no solution)
5) -3x+6y=-3
3x-y=8
-3x+6y= -3 -> y = 1/6(3x-3)
3x-y=8 -> y = 3x-8
1/6(3x-3) = 3x-8
3x-3 = 18x-48
x-1 = 6x - 16
5x = -15
x = -3
3x-y=8
3(-3)-y=8
-9-8 = y
y = -17
6) -6x+6y=24
-3x-8y=1
-6x+6y=24 -> y = 1/6(6x+24) -> y = x+4
-3x-8y=1 -> -3x-1 = 8y -> y = 1/8 (-3x-1)
1/8 (-3x-1) = x+4

write a equation in the form y= mx or y= mx + b to represent the relationship between the independent and dependent qualities?
Answer:
y = 10x
Step-by-step explanation:
Independent variable (x) = time (minutes)
Dependent variable (y) = distance (feet)
The line passes through the point of origin (0, 0), which means it represents a proportional relationship. Therefore, the equation would be in the form of y = mx. Where,
m = slope = y/x
Using any point on the line, say (5, 50),
m = 50/5
m = 10
To write the equation, substitute m = 10 into y = mx
Thus:
y = 10x
