The equation which is not necessarily true is that G'H' = 8 units.
What is the equation?
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraint.
Given that a polygon of GHIJ translates 8 units to the left to form polygon G 'H 'I 'J ' in the option it is necessary because GH is a side and G'H' will still be a side so they will be the same.
In option b G'G will be 8 units because the entire figure has shifted towards the left.
And the correct answer will be that G'H' = 8 units which are not true.

Using the segment addition postulate, which is true?
AB + BC = AD
AB + BC = CD
BC + CD = AD
BC + CD = BD
Answer: The answer is (d) BC + CD = BD.
Step-by-step explanation: We are given the number line and four points A, B, C and D on the line with co-ordinate -6, -1, 2 and 8 respectively.
We are to select the correct statement out of the given four.
(a) L.H.S. = AB + BC = 5 + 3 = 8,
R.H.S = AD = 14 ≠ 8.
So, this option is incorrect.
(b) L.H.S. = AB + BC = 5 + 3 = 8,
R.H.S = CD = 6 ≠ 8.
So, this option is incorrect.
(c) L.H.S. = BC + CD = 3 + 6 = 9,
R.H.S = AD = 14 ≠ 9.
So, this option is incorrect.
(d) L.H.S. = BC + CD = 3 + 6 = 9,
R.H.S = BD = 9.
So, this option is correct.
Thus, the correct option is (d).
A pattern for 1 1 uniform uses 12 12 yards of material. Boleslaw wants to know how many yards are needed for 8 8 uniforms. Chantal wants to know how many yards she will need to make 15 15 uniforms.
To find the amount of material needed for a certain number of uniforms, we can use a proportion and multiply the amount of material needed for 1 uniform by the desired number of uniforms.
Explanation:To find out how many yards are needed for 8 uniforms, we can set up a proportional relationship between the number of uniforms and the amount of material needed. We can do this by dividing the amount of material needed for 1 uniform by the number of uniforms, and then multiplying by the desired number of uniforms. The formula for this is (Amount of material needed for 1 uniform / Number of uniforms) * Desired number of uniforms. Using this formula, we can determine that 8 uniforms would require (12 yards / 1 uniform) * 8 uniforms = 96 yards of material.
To find out how many yards are needed for 15 uniforms, we can use the same formula. (12 yards / 1 uniform) * 15 uniforms = 180 yards of material.
Therefore, 8 uniforms require 96 yards of material, and 15 uniforms require 180 yards of material.

The function g(x) is a continuous quadratic function defined for all real numbers, with some of its values given by the table below.The quadratic function ƒ(x) is represented by the parabola below. x g(x) -3 0 -2 5 0 9 2 5 3 0 Select all the statements that are true. The function ƒ(x) has a maximum value at x = 4.5. The function g(x) has a minimum value of 0. The maximum value of g(x) is twice the maximum value of ƒ(x). Neither function has a minimum value.
The function g(x) has a minimum value of 0, but we cannot determine the maximum value of g(x) or compare it to the maximum value of f(x). The statements about the maximum value of ƒ(x) and the lack of minimum value for both functions are not supported by the given information.
Explanation:The function g(x) is a continuous quadratic function that can be represented by a parabola. From the given table, we can observe that the minimum value of g(x) is 0 and it occurs when x = -3 or x = 3. Therefore, the statement 'The function g(x) has a minimum value of 0' is true.
To determine the maximum value of g(x), we need to find the vertex of the parabola representing g(x). Since the function is continuous and quadratic, the vertex occurs at the axis of symmetry. The axis of symmetry is given by x = -b/2a, where a and b are the coefficients of the quadratic function. In this case, the equation representing g(x) is not given, so we cannot determine the exact maximum value of g(x) or compare it to the maximum value of f(x).
Based on the given information, we cannot determine whether the function f(x) has a maximum value at x = 4.5 or if the maximum value of g(x) is twice the maximum value of f(x). Therefore, the statements 'The function ƒ(x) has a maximum value at x = 4.5' and 'The maximum value of g(x) is twice the maximum value of ƒ(x)' are false.
Regarding the statement 'Neither function has a minimum value,' it is not accurate based on the given information. We already established that g(x) has a minimum value of 0.

An item costs $410 before tax, and the sales tax is $20.50 . find the sales tax rate. write your answer as a percentage.
The percentage of sales tax is 5%.
Given that, an item costs $410 before tax, and the sales tax is $20.50.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Let x% be the sales tax.
Now, x% of 410 = 20.50
0.01x ×410 = 20.50
⇒ 4.1x=20.50
⇒ x=20.50/4.1
⇒ x=5

What are the coordinates of point Q
Please only answer if you have the answer.
To find the coordinates of point Q when M(1,7) is the midpoint of PQ, and P(-8,3), we use the midpoint formula to get Q's coordinates as (10, 11).
Explanation:The question asks for the coordinates of point Q given that M(1,7) is the midpoint of PQ and the coordinates of point P are (-8,3). To find the coordinates of Q, we can use the midpoint formula which is (x1 + x2)/2, (y1 + y2)/2 where (x1, y1) are the coordinates of P and (x2, y2) are the coordinates of Q. Since M is the midpoint, its coordinates (1,7) equal these averages.
For x: (-8 + x2)/2 = 1For y: (3 + y2)/2 = 7Solving these equations for x2 and y2, we find the coordinates of Q to be (10, 11).

Describe how to graph the solution of
y ≤ −x2 + 2x.
We are given a inequality as:
[tex]y\leq -x^2+2x[/tex]
We know that the graph of this inequality will be a solid parabola ( since the inequality is with equality sign) .The parabola will be downward parabola ( Since for any general equation of parabola as y=ax^2+bx+c if a<0 then the parabola is downward and if a>0 then the parabola is upward)Also the roots of the parabola are the points where y=0.( The roots are: -x(x-2)=0
x=0 and x=2 are the roots of the parabola)
Also the region inside the parabola is shaded.(This could be checked by taking different points)
To graph the solution of y ≤ -x² + 2x, follow these steps: graph the equation y = -x² + 2x, determine the boundary line, and shade the appropriate region based on a test point.
Explanation:To graph the solution of the inequality y ≤ -x² + 2x, we can follow these steps:
Start by graphing the equation y = -x² + 2x as a parabola.Next, determine the boundary line which separates the region where y is less than or equal to the parabola from the region where y is greater than the parabola. In this case, the boundary line is the actual graph of the equation y = -x² + 2x.Then, choose a test point that is not on the boundary line and substitute its coordinates into the inequality to check if it is true. If it is true, shade the region that includes the test point. If it is false, shade the other region.By following these steps, you will be able to graph the solution of the inequality y ≤ -x² + 2x.
