Write an inequality for the graph weegy answer

It is safe to say that the line we have drawn on the graph is the solution set to our equation.

Thus the plane extends indefinitely in all directions. Once we have removed parentheses and have only individual terms in an expression, the procedure for finding a solution is almost like that in chapter 2. The parallel sides are called bases. Neither unknown will be easier than the other, so choose to eliminate either x or y.

Sometimes the form of an answer can be changed. Systems of Equations and Inequalities In previous chapters we solved equations with one unknown or variable. First, start at the origin and count left or right the number of spaces designated by the first number of the ordered pair.

If we take the same two numbers and multiply them by Their point of intersection will be the solution of the system. Here is an expression When we plug in different values of x, we also yield a different output as well.

First locate the point 0, Use the y-intercept and the slope to draw the graph, as shown in example 8. Since we are dealing with equations that graph as straight lines, we can examine these possibilities by observing graphs.

Then the graph is The slope of We now wish to compare the graphs of two equations to establish another concept. We get our points by just lining up the x value and y value to get their locations, and we can do this for any coordinate pair.

The symbols and used on the number line indicate that the endpoint is not included in the set. Our coordinate would be 0,-4which we call our y intercept. Graph a straight line using its slope and y-intercept. We can then use the Subtraction Property of Inequality to solve for e.

Could you possibly tell if the point represents or maybe? The actual point of intersection could be very difficult to determine. Usually, equations are written so the first term is positive. We then sketch the graph. The intersection of the two solution sets is that region of the plane in which the two screens intersect.

To graph the solution to this system we graph each linear inequality on the same set of coordinate axes and indicate the intersection of the two solution sets. We must multiply each term inside the parentheses by the factor preceding the parentheses. Example 15 Write an algebraic statement for the following graph.

Step 2 Adding the equations, we obtain Step 3 Solving for y yields Step 4 Using the first equation in the original system to find the value of the other unknown gives Step 5 Check to see that the ordered pair - 1,3 is a solution of the system.

Therefore, the system has as its solution set the region of the plane that is in the solution set of both inequalities. Graphs are very important for giving a visual representation of the relationship between two variables in an equation.

In the top line x we will place numbers that we have chosen for x. Thus, we have the solution 2, Notice in this example that r was left on the right side and thus the computation was simpler.

What relationship would she expect to see between the two stocks at the end of Tuesday?

Equations and Inequalities Involving Signed Numbers

Since the point 0,0 is not in the solution set, the half-plane containing 0,0 is not in the set. The number lines are called axes. In this table we let y take on the values 2, 3, and 6.

What positive number can be added to 2 to give 5?Number lines help make graphing the union of two inequalities a breeze! This tutorial shows you how to graph two inequalities on the same number line and then find the union.

Systems of Equations and Inequalities

As with one-step inequalities, we should always substitute values into the original inequality to check the answer. In this problem we found that, so we should pick a value that is less than. Let’s choose 0.
