Algebra Balance Scales This virtual manipulative allows you to solve simple linear equations through the use of a balance beam. That means that 35 hot dogs were sold. Rational Inequalities — We continue solving inequalities in this section.
If you are subtracting a number, you want to add on both sides, and if you are adding a number, you want to subtract on each side. As we will see we will need to be very careful with the potential solutions we get as the process used in solving these equations can lead to values that are not, in fact, solutions to the equation.
If you need a review on solving linear equations, feel free to go to Tutorial How many hot dogs were sold and how many sodas were sold? Circles — In this section we discuss graphing circles.
We will also define simplified radical form and show how to rationalize the denominator. This gets rid of fractions. The equations in this tutorial will lead to either a linear or a quadratic equation.
In addition, we will introduce the standard form of the line as well as the point-slope form and slope-intercept form of the line.
If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width. Polynomial Functions - In this chapter we will take a more detailed look at polynomial functions.
Here are more examples, since solving these is an important foundation of algebra. Even after doing that, there is still a 3 multiplied by the variable, so division will be necessary to eliminate it.
We will also take a quick look at using augmented matrices to solve linear systems of equations. When solving radical equations, extra solutions may come up when you raise both sides to an even power.
Sometimes you start out with two or more radicals in your equation. Rational Exponents — In this section we will define what we mean by a rational exponent and extend the properties from the previous section to rational exponents.
If the top section of the calculator becomes to tall for your viewport, tapping in the "Enter a problem Note that if you are unsure how to enter a problem, tap the stacked dots icon in the upper right-hand corner to see a list of example entries.
Linear Systems with Two Variables — In this section we will solve systems of two equations and two variables. Now we are ready to apply these strategies to solve real world problems! We also define the domain and range of a function. The strategy for getting the variable by itself with a coefficient of 1 involves using opposite operations.
More on the Augmented Matrix — In this section we will revisit the cases of inconsistent and dependent solutions to systems and how to identify them using the augmented matrix method. Integer Exponents — In this section we will start looking at exponents.Practice solving equations that take two steps to solve.
For example, solve = x/4 + 2. Solving Inequalities Practice Problems. Now that you've studied the many examples for solving inequalities, are you ready for some practice problems?. Let's quickly recap some of the steps for solving these practice problems. A two-step equation is as straightforward as it sounds.
You will need to perform two steps in order to solve the equation. One goal in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign.
The other goal is to have the number in front of the variable equal to one. The variable does not. Quickly check your math homework with this free online algebra calculator for solving algebra, trigonometry, calculus, or statistics equations.
