Write the relation as a set of ordered pairs.

A relation. An arrow goes from negative 2 to 4, 0 to 0, 2 to 4.
a.
ordered pairs: {(4, –2), (0, 0), (2, 4)}
b.
ordered pairs: {(–2, 4), (0, 0), (4, 2)}
c.
ordered pairs: {(–2, 4), (0, 0), (2, 4)}
d.
ordered pairs: {(4, –2), (0, 0), (4, 2)}



Please select the best answer from the choices provided


A
B
C
D

The ordered pairs are, (-2, 4), (0, 0), (2, 4).

Option C is true.

Here,

Given that;

In a relation an arrow goes from -2 to 4, 0 to 0, 2 to 4.

We have to find ordered pairs.

What is Ordered pairs in set?

A function f from a set A to a set B is a set of ordered pairs {(x, y)} such that x is in the set A and y is in the set B.

(x, y) is an ordered pair in f.

Where, for every x ∈ A there is exactly one y ∈ B.

Now,

In a relation an arrow goes from -2 to 4, 0 to 0, 2 to 4.

Hence, by definition of ordered pairs;

We get the ordered pairs,

(-2, 4)

(0, 0)

(2, 4)

Hence, The ordered pairs are, (-2, 4), (0, 0), (2, 4)

Option C is true.

Sari applied the distributive property using the greatest common factor to determine the expression that is equivalent to 84 +40. Her work is shown below.

Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

84 + 40 = 2 (42 + 20)

What statement best describes Sari’s error?
Sari did not use correct factors for 84 in the equation.
Sari did not use correct factors for 40 in the equation.
Sari did not use two equivalent expressions in the equation.
Sari did not use the greatest common factor in the equation.
