Answer:

let required no be x

$\frac{1}{7} = \frac{x}{42}$

by doing crisscrossed multiplication

$42 \times 1 = 7 \times x$

42=7x

dividing both side by 7

$\frac{42}{7} = 7x \div 7$

Which of the sets of ordered pairs represents a function?

IgorC [24]

Answer:

Neither set A nor set B represents a function.

Step-by-step explanation:

According to the definition of a function, for each input there exists a unique output. In other word for each value of x there exists unique value of y.

In set A we have four ordered pair (-4,5),(1,-1),(2,-2) and (2,3).

It means for x=2, we have two values of y, i.e., -2 and 3.

Since for a single value of x there exist more than one value of y, therefore set A is not a function.

In set B we have four ordered pair (2,2),(3,-2),(9,3) and (9,-3).

It means for x=9, we have two values of y, i.e., -3 and 3.

Since for a single value of x there exist more than one value of y, therefore set B is not a function.
