How do you solve equations with power variables?
To solve equations with power variables, first isolate the term with the variable raised to a power. If it's in the form (x^n = a), take the (n)-th root of both sides to solve for (x), remembering to consider both positive and negative roots if (n) is even. For more complex equations, you may need to rearrange the equation or use logarithms for variables in the exponent. Always check your solutions by substituting them back into the original equation.
Why is it important to check your solution when solving an equation?
Checking your solution is crucial because it verifies the accuracy of your work and ensures that no mistakes were made during the solving process. It helps confirm that the solution satisfies the original equation, providing confidence in the result. Additionally, this practice can highlight any errors in reasoning or calculation, allowing for corrections before finalizing your answer. Ultimately, verifying solutions promotes a deeper understanding of the problem and reinforces good mathematical habits.

What The sum of 3 consecutive integers that equals 252?
Let the three consecutive integers be ( x ), ( x+1 ), and ( x+2 ). The equation can be set up as ( x + (x + 1) + (x + 2) = 252 ). Simplifying this gives ( 3x + 3 = 252 ), which leads to ( 3x = 249 ) and ( x = 83 ). Therefore, the three consecutive integers are 83, 84, and 85.
In the expression (5x), the number 5 is a coefficient. It indicates how many times the variable (x) is multiplied. Essentially, it tells us that (x) is being scaled or multiplied by 5.
How do you write 81 in three different exponents?
You can express 81 using different exponents as follows: (81 = 3^4), since (3 \times 3 \times 3 \times 3 = 81). Additionally, (81 = 9^2) because (9 \times 9 = 81) and (9) can also be written as (3^2), giving (81 = (3^2)^2 = 3^4). Lastly, (81 = 81^1) is another representation, where any number to the power of 1 remains unchanged.
A function represented by a combination of equations, each corresponding to a specific part of the domain, is called a piecewise function. In a piecewise function, different formulas apply to different intervals or segments of the input variable. This allows for more complex behaviors and shapes that can adapt to various conditions within the domain.
What does b stand for in point slope form?
In point-slope form of a linear equation, which is expressed as (y - y_1 = m(x - x_1)), the letter (b) typically represents the y-intercept of the line when the equation is rewritten in slope-intercept form (y = mx + b). However, in the context of point-slope form itself, (b) is not directly used; instead, the focus is on the slope (m) and a specific point ((x_1, y_1)) on the line.
How do you write procedure for NOP?
To write a procedure for a NOP (Network Operating Procedure), begin by clearly defining the purpose and scope of the procedure, ensuring it aligns with organizational policies. Next, outline the step-by-step processes involved, including roles and responsibilities, necessary tools, and safety precautions. Incorporate any relevant diagrams or flowcharts to enhance clarity, and finally, establish a review and approval process to ensure the procedure remains current and effective.
What numbers does the square root of 125 fall between?
The square root of 125 falls between the numbers 11 and 12. This is because (11^2 = 121) and (12^2 = 144), and since 125 is between 121 and 144, its square root will be between 11 and 12. More precisely, ( \sqrt{125} ) is approximately 11.18.
Simplify and solve this equation 4m plus 9 plus 5m-12 equals 42?
To simplify the equation (4m + 9 + 5m - 12 = 42), combine like terms: ( (4m + 5m) + (9 - 12) = 42) simplifies to (9m - 3 = 42). Next, add 3 to both sides: (9m = 45). Finally, divide by 9 to find (m = 5).
Can real world problems that have more than one answer be described by relations?
Yes, real-world problems with multiple solutions can be described by relations, as these problems often involve complex interactions among variables. In such cases, a relation can capture the different outcomes or solutions based on varying inputs or conditions. For instance, in economics, supply and demand can be represented as a relation, where multiple price points can exist for different quantities. Ultimately, these relations help illustrate the range of possible solutions within a given context.
What function does the cellbelum have?
The cellbelum, a term that seems to be a misspelling or a confusion with "cell membrane" or "cerebellum," does not refer to a recognized biological structure. If you meant "cell membrane," it functions as a protective barrier that regulates the movement of substances in and out of the cell, maintaining homeostasis. If you meant "cerebellum," it is a part of the brain that coordinates voluntary movements, balance, and motor learning. Please clarify if you meant something else!
The x-value in a function called?
The x-value in a function is commonly referred to as the "input" or "independent variable." It represents the value that is fed into the function to produce an output, which is typically called the "y-value" or "dependent variable." In mathematical notation, a function is often expressed as ( f(x) ), where ( x ) is the input.
To simplify the expression (3(2x + 4x)), first combine the terms inside the parentheses: (2x + 4x = 6x). Then, multiply by 3: (3 \times 6x = 18x). Therefore, the simplified expression is (18x).
An 82 is generally considered a B in most grading systems, as it typically falls within the range of 80-89, which corresponds to a B grade. However, grading scales can vary by institution, so it's important to check the specific grading policy in use.
What do expressions and equations have in common?
Expressions and equations both involve mathematical symbols and represent relationships between quantities. An expression is a combination of numbers, variables, and operations without an equality sign, while an equation states that two expressions are equal, typically including an equality sign. Both are fundamental concepts in algebra, used to model and solve problems involving numerical relationships. Ultimately, they serve as tools for conveying mathematical ideas and performing calculations.
How do you find x in an equation?
To find ( x ) in an equation, isolate ( x ) on one side of the equation. This typically involves performing inverse operations, such as adding, subtracting, multiplying, or dividing both sides by the same number. Simplify the equation step by step until you have ( x ) alone. Finally, verify your solution by substituting ( x ) back into the original equation.
The expression "2x plus 6y0" seems to contain a typo because "y0" isn't a standard variable notation. If you meant "6y," then the expression would simply be 2x + 6y. If you're referring to a specific value or function related to "y0," please clarify for a more accurate response.
What is 6x plus 21y and 3(2x plus 7y) equal?
To solve the equation, we first expand the expression (3(2x + 7y)). This gives us (6x + 21y). Therefore, both expressions (6x + 21y) and (3(2x + 7y)) are equal to each other, confirming that they represent the same value.
What is the point 0 0 on a graph called?
The point (0, 0) on a graph is called the origin. It is the point where the x-axis and y-axis intersect in a Cartesian coordinate system. The coordinates represent the values of zero for both the x and y variables, serving as a reference point for plotting other points on the graph.
To calculate the mass of the solid metal cylinder, use the formula: mass = density × volume. Given a density of 2.6 g/cm³ and a volume of 6.3 cm³, the mass is calculated as follows:
Mass = 2.6 g/cm³ × 6.3 cm³ = 16.38 grams.
Thus, the mass of the cylinder is 16.38 grams.
Is it possible to determine the square (2nd) root of a negative number?
Yes, it is possible to determine the square root of a negative number by using imaginary numbers. Specifically, the square root of a negative number can be expressed using the imaginary unit (i), where (i) is defined as the square root of -1. For example, the square root of -4 is written as (2i). This concept is foundational in complex number theory.
A mapping diagram can represent a function but not a relation.?
This statement is incorrect. A mapping diagram can represent both functions and relations. A relation is any set of ordered pairs, while a function is a specific type of relation where each input (or domain element) is associated with exactly one output (or range element). In a mapping diagram, if each input has a single output, it represents a function; if an input has multiple outputs, it represents a relation that is not a function.
