We often use functions to model or represent situations and relationships. These representations can be as equations, graphs, ta

bles, or even verbal descriptions. What does it mean to "represent" something? In what other situations have you heard that term used, and how was its meaning in those situations similar to its usage in algebra?​

A representation is the provision of a portrait or a description of an object,

a  person, or an observed situation in a particular (defined) way.

  • In algebra, functions are used to accurately serve as representation that show equivalence of observed phenomena or system.

  • Graphs are used to present data in a pictorial form, such that an end user can more quickly and or easily understand the information conveyed.

  • Equations are used to represent equivalent situations in a manner to provide guidance that enable a user of the equation to find the required result or information.

  • Tables represent the data in a situation in an organized manner.

  • Venn diagrams are used to represent the relationship between group numbers in a set.

Other situations where the term is used are;

  • Athletes representing countries in tournaments

The similarity in the usage of the term to algebra is that the athletes have

the attributes of the country they represent, such that the people of the

country are viewed as strong as the athletes representing them.

The difference of two numbers is 1. What is the smallest possible value for the sum of their squares?​
Stella [2.4K]
X= 1 number
Y= a number that is 1 less than x
Y= x-1

The sum of squares=

X^2 + (x-1)^2 = x^2 + x^2 - 2x + 1
X^2 + x^2 - 2x + 1 = 2x^2 - 2x + 1

Assuming that integers = numbers. We could try some values

When x = 0, the sum of squares = 1
When x = -1, the sum of squares = 4
When x = 1, the sum of squares = 1

If you put this into a graph, it is a parabola and we see that the minimum value hits at x = 1/2.

To check this value:

2x^2 - 2x + 1 = 2·(1/4) - 2·(1/2) + 1
2·(1/4) - 2·(1/2) + 1 = 1/2 - 1 + 1
1/2 - 1 + 1 = 1/2

When you look back at the question, it asks for 2 answers

X= 1/2
X-1 = -1/2

What is the sum of their squares?

1/4 + 1/4 = 1/2

That fits with graph too.

Answers: 1/2 and -1/2

Hope this helps!!

4. Which equation describes the line that contains the points (6,2) and (12,4)?
saveliy_v [14]

Answer:

(a) y = 1/3 x is the correct equation.

Step-by-step explanation:

The given points are (6,2) and (12,4)

Now, if these points lie on any equation then they should satisfy the equation on which they lie.

CHECK FOR  equation  y = 1/3 x

if x = 6, y = 2 , then 2 = 1/3(6)  , True

if x = 12, y = 4, then 4 = 1/3(12). True

So, y = 1/3x contains both the points.

CHECK FOR  equation  y = 3x + 2

if x = 6, y = 2 , then 2 ≠ 3(6) + 2  

if x = 12, y = 4, then 4 ≠ 3(12). + 2

So, y = 3x  + 2  do not contain both the points.

CHECK FOR  equation  y = 3x  

if x = 6, y = 2 , then 2 ≠ 3(6)  

if x = 12, y = 4, then 4 ≠ 3(12).

So, y = 3x  do not contain both the point

Hence,  (a) y=1/3x is the correct equation.
