How do you find the solution to a linear equation?
The solution to a linear equation can be found by balancing the variables.
A linear equation is one that carries a degree of one as its maximum value. None of the variables in these equations, thus, has an exponent greater than one. Moreover, the graph of these equations will always also be a straight line. A mathematical equation resembles a balance scale with identical weights on either side.
An equation remains valid even if the same integer is added to or subtracted from both sides. Similarly to this, an equation is accurate if the same integer is multiplied or divided into both sides. We place the constant on one side of the equation, and the variables on the other, and then we calculate the value of the unknown variable. This is how a linear equation with a single variable is solved.

What is the point of concurrence of perpendicular bisectors of a triangle?
The points of concurrency of perpendicular bisectors of triangle is circumcenter.
A point of concurrency shared by three or more lines is referred to as a single point of concurrency. Constructed lines in triangle interiors are excellent places to look for points of convergence.
When you construct a triangle's medians, perpendicular bisectors, angle bisectors, or altitudes, you create a point of concurrency for each of them.
Because the triangle can have four distinct types of line segments, it can have four distinct points of convergence. Each point of concurrency represents the intersection of a particular type of line segment: centroid, circumcenter, incenter, and orthocenter.
The centroid of the triangle is the point of convergence shared by the three medians.The point at which the triangle's three angle bisectors intersect is known as the incenter.The three perpendicular bisectors will intersect at the circumcenter, which is a point of convergence.The orthocenter is the point at which the three altitudes/heights of a triangle intersect.Thus, the points of concurrency of perpendicular bisectors of triangle is circumcenter.

Find the volume of a with a square base where the perimeter of the base is 8.7ft and the height of the pyramid is 9.2ft
Answer:
Volume of a pyramid with a sqaure base is 14.5 ft³.
The perimeter of a form represents the gap around it, the vicinity of a form is the surface or flat area that the shape covers (in 2D) even as the quantity of a form is the distance it occupies in actual lifestyles (in 3D).
The perimeter of the base is 8.7ft
The length of the side of the base is:
8.7÷4=2.175 ft
The area of the base
S=(2.175)² =4.730625 ft²
The volume of the rectangular pyramid =
V= 1/3 × area of its base ×area of heights
V = 1/3 × 4.730625 ×9.2
V≅ 14.3 ft³

The pressure is 38.5 Newton per square meter (N/m²)
What is temperature?Temperature can be defined as the quantity that is used to measure the degree of hotness or coldness of a body in °Kelvin or ° Celsius.
When the pressure of a glass varies directly with the temperature, this means that once there is an increase in temperature there should be an increase in pressure of the medium too.
To calculate the new pressure the gas formula is used;
Where,
P1 = 18.9N/m²
T1 = 90k
V1 = 20m³
T2 = 110k
V2 = 12m³
P2 = X
P1V1/T1 = P2V2/T2
Make P2 the subject of formula;
P2 = P1V1T2/T1V2
P2 = 18.9×20×110/90×12

Use the appropriate compound interest formula to compute the balance in the account after the stated period of time
$4,000 is invested for 15 years with an APR of 3% and monthly compounding.
The balance in the account after 15 years is $____
The balance in the account after 15 years is $6, 269.73.
How to find the balance on the account?The balance on the account after 15 years is referred to as the future value of the account. To find this future value, the future value formula can be used which is:
Future value = Amount invested x ( 1 + Periodic rate ) ^ number of periods
Amount invested = $4, 000
Periodic Rate = 3% APR / 12 months in year = 1/4 %
Number of periods = 15 years x 12 months = 180 months
The balance in the account after 15 years is:
= 4, 000 x ( 1 + 1/4 %) ¹⁸⁰
= 4, 000 x 1.0025 ¹⁸⁰

Highest Common Factor (HCF) 4 \4 and
Least Common Multiple (LCM) 60
The pairs of numbers that have HCF 4 and LCM 60 are : 4 and 60 , 12 and 20.
What is LCM and HCF?In this case, we must use the following relationship between HCF and LCM:
Number 1 + Number 2 = HCF x LCM
In other words, multiplying both factors equals multiplying the given numbers that we are looking for. We don't know the numbers yet, but we can get an idea of what they could be by calculating the product of the factors:
4 x 60 = 240
We know that the products should be 240 and that if the HCF is 4 , then both numbers can be divided by 4 as the highest factor, so let's write the multiple of 7:
4-digit multiples:
4, 8, 12, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60
By using, we can get an idea: if 60 x 4 = 240, all we need to do is find the other two numbers that result in 240:

find the domain and range of 1 - x^2
The range and the domain of the function f(x) = 1 - x^2 is less than or equal to 1 and all values of x are a real number (R).
Domain: x ∈ R
Range: f ( x ) ≤ 1, ∈ R
f ( x ) = 1 − x^2 is defined for all Real values of x, and therefore the domain is all real values ( R ).
x^2 has a minimum value of 0 (for x ∈ R ) and therefore − x^2 has a maximum value of 0 and − x^2 + 1 = 1 − x^2 has a maximum value of 1.

What type of triangle is def?
An isosceles triangle therefore has both two equal sides and two equal angles.
What is traiangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
What is isosceles triangle?
An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.
Any triangle with (at least) two equal sides is said to be isosceles. The remaining side in the previous illustration has length in addition to the two equal sides. This characteristic equates to the triangle's two angles being equal. Therefore, an isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and skelos are the source of the name (leg).
An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal. Therefore, an equilateral triangle is a specific example of an isosceles triangle that has equal sides and angles on all three of its faces. The isosceles right triangle is yet another unique instance of an isosceles triangle.
The Pythagorean theorem can be used to determine the height of the isosceles triangle shown in figure:
[tex]h = \sqrt{b^2-\frac{1}{4}a^2 }[/tex]
Consequently, the region is given by:
A=1/2ah
A = [tex]\frac{1}{2}a\sqrt{b^2-\frac{1}{4}a^2 }[/tex]
[tex]A = \frac{1}{2}a^2\sqrt{\frac{b^2}{a^2}-\frac{1}{4} }[/tex]

Select the best interpretation of the following equation.
11 - y = 3
The most general interpretation of the linear equation 11 - y = 3 is:
"The difference between 11 and a number is equal to 3"
How to interpret the equation?Here we have the following linear equation:
11 - y = 3
Which only depends on the variable y, that we assume it can take any real number as its value.
The linear equation says that if we subtract the number y from eleven, the outcome is 3.
Or we can use other words, like: "The difference between 11 and a number is equal to 3"
Where subtraction and difference are words that reffer to the same operation, which is the subtraction: A - B.
