Does this set of ordered pairs form a function?

zhenek [66]

Considering that each input is related to only one output, the correct option regarding whether the relation is a function is:

A. yes.

<h3>When does a relation represent a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

For this problem, we have that:

The input is a number.

The output is an activity.

There are no repeated inputs, hence the relation is a function and option A is correct.

Graph the solution of the inequality: 3/7 (35x-14) ≤ 21x/2 + 3

hammer [34]

Hello there!

In order to graph the solution, we need to solve it first.

So let's start....

3/7(35x - 14) ≤ 21x/2 + 3

15x -6 ≤ 21x/2 + 3

15x - 21x/2 ≤ 3 + 6

9x/2 ≤ 9

x ≤ 9* 2/9

x ≤ 18/9

x ≤ 2

See the picture for the graph

Please let me know if you have questions about the answer.

Thanks!

Solve the equation with the problem set {-28,-8,8,28} |10-x|=18

Elden [556K]

Answer:

{-8,28}

Step-by-step explanation:

|10-x|=18

The absolute value has two solutions, one positive and one negative.

10-x = 18 and 10-x = -18

Subtract 10 from each side

10-10-x = 18-10 10-10-x=-18-10

-x = 8 -x = -28

Multiply each side by -1

x = -8 x = 28
