Solving Exponential and Logarithmic Equations Exponential Equations (variable in exponent position) 1. Isolate the exponential portion ( base exp onent ): Move all non-exponential factors or terms to the other side of the equation. 2. Take ln or log of each side of the equation. • Make sure to use...
that hold true for the equation, solving quadratic equations requires much more than simply isolating the variable, as is required in solving linear equations. This piece will outline the different types of quadratic equations, strategies for solving each type, as well as other methods of solutions such...
To solve a system of equations by addition or subtraction (or elimination), you must eliminate one of the variables so that you could solve for one of the variables. First, in this equation, you must look for a way to eliminate a variable (line the equations up vertically and look to see if there are...
1. Solve S = 4v2 for v.(1 point) Get rid of 4 by dividing both sides by 4 s/4 = v^2 +/- square root of (s)/2=v 2. Solve M = 2x + 3y for y. (1 point) 3y= m - 2x y= (m - 2x)/3 y = (m - 2x)/3 3. Solve t = p+r/ 6 for r. (1 point) t = p + 3r / 6 t - p = 3r / 6 Divide both sides by 6 ...
There are two main ways to solve equations, algebraically or by using matrices. There are also different subcategories of each way to solve the equations. Using matrices or solving algebraically has some differences and similarities. There are a few ways to solve equations algebraically. One line of...
What Factors Should I Consider When Choosing a Career? Some people spend their entire lives asking themselves what they want to be when they grow up. Other people know from childhood and by following an interior compass, they end up in a career that never feels like going to work. If you're somewhere...

the mud system when you are going to purchase the mud equipment: 1) Type of drill you will be using 2) The drill rate 3) The type of solids 4) The length of your bore 5) The GPM of the pump 6) The tank volume you will need 7) The number of cones 8) The screen size These factors are important...
In mathematics, an equation is a formula of the form A = B, where A and B are expressions that may contain one or several variables called unknowns, and "=" denotes the equality binary relation. Although written in the form of proposition, an equation is not a statement that is either true or false,...

about remainder. Consider N = DQ + R, where D is non-zero, Q and R are integers and 0≤ R< D. In the foregoing equation; N is dividend, D is divisor, Q is quotient and R is the remainder. When R is zero, we say that the number (N) is completely divisible by D. Ground Rules: The following three ground...
equation In mathematics, an equation is an equality containing one or more variables. Solving the equation consists of determining which values of the variables make the equality true. In this situation, variables are also known as unknowns and the values which satisfy the equality are known as solutions...
Balancing Oxidation-Reduction Equations by the Oxidation Number Change Method Four Easy Steps: 1. Determine the oxidation numbers of the species being oxidized and reduced (and make sure there are the same number of atoms on each side). 2. Balance the changes in oxidation numbers by multiplying by the...
