Question

Which are equal ordered pairs in each of the following?

a) (15) and (7, 3)
b) (3, 4.5) and (1.5, 4.5)
c) (2, 10) and (4, 5)
d) (4 + 9, 21 7) and (13, 3)

Answer 1

To determine if ordered pairs are equal, compare their x and y values. If both values are the same, the pairs are equal.

Step-by-step explanation:

In order to determine which ordered pairs are equal, we need to compare their x and y values. If both the x and y values are the same for two pairs, they are considered equal.

a) (15) and (7, 3): In this case, the ordered pair (15) has only one value, while (7, 3) has two values. Therefore, they are not equal.

b) (3, 4.5) and (1.5, 4.5): Both pairs have the same y value of 4.5, but their x values are different. Therefore, they are not equal.

c) (2, 10) and (4, 5): Both pairs have different x and y values, so they are not equal.

d) (4 + 9, 21 7) and (13, 3): The ordered pair (4 + 9, 21 7) can be simplified to (13, 21 7). However, (13, 21 7) is not the same as (13, 3). Therefore, they are not equal.
