Where do you find the solution to a system?.
There are several methods for finding the solution to a system of equations, which include:
1. Graphing: This method involves plotting the equations on a coordinate plane and finding the point(s) of intersection. This method is useful when the system has a small number of variables and the equations are in the form of y = mx + b.
2. Substitution: This method involves solving one of the equations for one variable and then substituting that expression into the other equation. This method is useful when one equation is easier to solve than the other or when one equation is a simpler form than the other.
3. Elimination: This method involves adding or subtracting the equations to eliminate one of the variables. This method is useful when the variables are in similar forms and the coefficients are easy to add or subtract.
4. Matrix method: This method involves solving the system of equations in matrix form using matrix algebra techniques such as Gaussian elimination, Gauss-Jordan elimination and Cramer's rule. This method is useful when the system of equations have a large number of variables and when you want to solve system of equations in a more efficient and less time-consuming way.
5. Numerical methods: This method involves using numerical techniques such as Newton-Raphson method, Iterative methods to approximate the solution of a system of equations.
It is important to note that in some cases, a system may have no solution or infinitely many solutions. A system has no solution when the equations are inconsistent, meaning they cannot be true at the same time. A system has infinitely many solutions when the equations are dependent, meaning one equation can be derived from the other equation

For each function, 1) find the inverse (if it exists), 2) find the domain and range for both f and f^-1
1) y=1/5^(1-x)+2
2)1-5^x/5^(x-1)
3)y=log1/5(x+1/2)-1
Answer:
1. y = 1/5^(1-x) + 2
The inverse function, denoted as f^-1(x), can be found by swapping the x and y variables and solving for y.
So, x = 1/5^(1-y) + 2
To find the inverse, we need to solve for y:
y = 1 - log(5, x-2)
Note that the inverse only exists if the original function is a one-to-one function, meaning that it assigns a unique output to each input.
The domain of f is all x such that x > 2. And the range of f is all y such that y > 2. The domain of f^-1 is all x such that x > 2 and the range of f^-1 is all y such that y > 1.
----------------------------------------------------------
2. 1 - 5^x/5^(x-1)
The inverse function, denoted as f^-1(x), can be found by swapping the x and y variables and solving for y.
So, x = 1 - 5^y/5^(y-1)
To find the inverse, we need to solve for y:
y = log(5, 1/(x+1)) + 1
Note that the inverse only exists if the original function is a one-to-one function, meaning that it assigns a unique output to each input.
The domain of f is all x such that x < 1. And the range of f is all y such that 0 < y < 1. The domain of f^-1 is all x such that x < 1 and the range of f^-1 is all y such that y > 1.
--------------------------------------------------------------
3. y = log1/5(x+1/2)-1
The inverse function, denoted as f^-1(x), can be found by swapping the x and y variables and solving for y.
So, x = log1/5(y+1) - 1/2
To find the inverse, we need to solve for y:
y = 5^(x+1/2) - 1
Note that the inverse only exists if the original function is a one-to-one function, meaning that it assigns a unique output to each input.
The domain of f is all x such that x exists. And the range of f is all y such that y > -1. The domain of f^-1 is all x such that x exists and the range of f^-1 is all y such that y > 0.
-----------------------------------------------------------------
In summary,
1. f^-1(x) = 1 - log(5, x-2) Domain: x>2, Range: y>2.
2. f^-1(x) = log(5, 1/(x+1)) + 1 Domain: x<1, Range: 0<y<1.
3. f^-1(x) = 5^(x+1/2) - 1 Domain: x exists, Range: y>-1.

meet the requirement.
minutes in order to
Stella must run between 248 minutes and 252 minutes in order to meet the requirement.
What is the time-to-minute conversion?
As an hour consists of 60 minutes, we can convert hours into minutes by multiplying hour by 60. So, for example, if one wants to convert 3 hours into minutes, one can do it by multiplying 3 by sixty which will give 3 x 60 = 180 minutes.
To figure out the range of times within which Stella must finish the marathon in order to meet the requirement of finishing within 2 minutes of the 4:10 pace time,
we can use the following steps:
Convert the pace time of 4:10 to minutes.
Since there are 60 minutes in an hour, 4:10 is equal to 4 * 60 + 10 = 250 minutes.
Add 2 minutes to the pace time. Since Stella must finish within 2 minutes of the pace time, this gives us a finish time of 250 + 2 = 252 minutes.
Subtract 2 minutes from the pace time. Since Stella must finish within 2 minutes of the pace time, this gives us a finish time of 250 - 2 = 248 minutes.
The range of times within which Stella must finish the marathon in order to meet the requirement is 248 to 252 minutes.

____ is standard deviation a measure of center or a measure of variation
Standard deviation is a measure of variation.
The degree of variance or dispersion in a set of data values is measured statistically using the standard deviation. It reveals how far the data values differ from the data set's average. Data points tend to be close to the mean when the standard deviation is low, and are dispersed over a larger range when the standard deviation is high.
While measurements of the centre, such as mean, median, and mode, are used to describe a data set's central tendency. The median is the midway value when a data set is ordered, and the mode is the value that appears in a data set the most frequently. The mean is the sum of the data divided by the number of observations.

How do you solve log base questions?.
The answer to the equation for the logarithm of 1 in base 7 is x=0, where x is the power to which 1 must be raised in order to obtain the value 7.
The definition of the logarithm function, which is the inverse of the exponential function and reads log b(x) = y, is by = x. To put it another way, it reflects the increment in base b that must be raised in order to obtain the value x.
When solving log 7(1), we are seeking the power to which 7 must be increased in order to obtain the value 1.
Since 1 is the result of raising any number to the power of 0, we may state that 70 = 1, which implies that log 7(1) = 0.
Finding the value of x that makes the equation log 7(x) = 1 true is necessary to solve log base 7 1.
Log b(x) = y signifies that b = y using the definition of a logarithm.
Therefore, we can put 1 = 7x and obtain x = log7(1) = 0 to solve log7(1).
So, x=0 is the answer to the logarithm in base 7 of 1.
