Step-by-step explanation:

Given

See attachment for mapping diagrams

Required

Which represent function

For a mapping to be considered a function, each element of the input set must only point to 1 element of the output set.

Base on the above analysis, we have:

<u>Map A</u>

1 points to 6; 2 to 7; 3 to 8; and 4 to 9

<em>This is a function</em>

<u>Map B</u>

2 points to 0; 4 to 0; 6 to 0; and 8 to 0

<em>This is a function</em>

<u></u>

<u>Map C</u>

1 points to 8; 3 to 8; 5 to 9; and 7 to 9

<em>This is a function</em>

<u>Map D</u>

0 points to 2 and 5; 3 points 7 and 9

Blababa [14]

Hi there! :)

<u><em>Answer:</em></u>

<u><em>x=23</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

This lesson it's about addition property of equality.

First, you add by 8 from both sides of an equation.

x-8+8=15+8

And then, you add by the numbers. Simplify and solve.

15+8=23

Final answer: → x=23

Hope this helps!

Thanks!

Have a great day!

The sum of the ages of Mr Lin and his son Ethan is 38 years. In three years' time, Mr Lin will be three times as old as his son.
Sati [7]

Answer:

Mr.Lin's present age is 30 years now. His son is 8 years old now.

Step-by-step explanation:

Let L = Mr.Lin's present age,

   S = his son's present age.

First equation  is

L + S = 38.       (1)

The second equation is  

L + 3 = 3*(S+3)   (2)   ("In three years' time, Mr.Lin will be three times as old as his son.")

From (1), express S = 38-L and substitute it into (2). You  will get

L + 3 = 3*((38-L)+3),   or

L + 3 = 114 - 3L + 9,

4L = 114 + 9 - 3,  

4L = 120,

L = 30.
