Q. What is the set of the first numbers of the ordered pairs?
domain
Q. Which of the following best describes the first number in an ordered pair of numbers?
The coordinates of a point are called an ordered pair because the order of the two numbers is important. The first number in the ordered pair is the x coordinate. It describes the number of units to the left or right of the origin. The second number in the ordered pair is the y coordinate.
Q. What ordered pair describes the origin?
The center of the coordinate system (where the lines intersect) is called the origin. An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate.
Q. What is an ordered pair in sets?
An ordered pair consists of two elements that are written in the fixed order. So, we define an ordered pair as: • The pair of elements that occur in particular order and are enclosed in brackets are called a set of ordered pairs.
Q. How do you determine if the set is a function?
How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!
Q. How do you separate ordered pairs?
When you format ordered-pair answers, enclose all ordered-pair answer values in parentheses. Separate the coordinates in the ordered pair with a comma. Do not include spaces between the coordinates and the comma.
Q. What makes not a linear equation in two variables?
A system of nonlinear equations is a system of two or more equations in two or more variables containing at least one equation that is not linear. Recall that a linear equation can take the form A x + B y + C = 0 /displaystyle Ax+By+C=0 Ax+By+C=0. Any equation that cannot be written in this form in nonlinear.
