How do graphs and equations reveal information about a relationship between two quantities

Mathematics

When two quantities have a relationship, there is a corresponding equation that could describe it. These two quantities may be expressed in variables of x and y. When you plot the graph, you may see a line or a curve. This presents the trend of the relationship of the two quantities when the independent variable changes.

Answer with explanation:

→→→The relationship between two Quantities can be expressed in either linear form which means Direct relationship or inverse relationship.

This can be expressed in the following way:

 →  y=a x +b------(1)

or

\rightarrow y=\frac{k}{x}

                                       --------------------------(2)

→You can take any of the variable as Independent Variable and another as Dependent Variable.

→→→Equation (1) shows direct relationship between  two variables whereas equation (2) shows inverse relationship between two variables.

When you represent this in graphical form one will be Linear and other will be in the shape of Rectangular Hyperbola.

For example:

→ y=2 x +3

And→→, \rightarrow y=\frac{2}{x}

Can be represented graphically as follows.

What multiple of 7 is also a factor of 7
enyata [817]
<span>The answer is 7. Seven is a prime number, which means that its multiples are 1 and itself (7): 7 = 1 * 7. To find out which one is a factor of 7, we should divide each of them by 7. 1/7 will be a decimal number and 7/7 = 1, which is a whole number. Thus, 7 will be a multiple of 7 and also a factor of 7.Hope this helps. Let me know if you need additional help!</span>

The original price of a computer game is $45. The price is marked down by $18. What percent of the original price is the markdow
natali 33 [55]

Answer:

60%

Step-by-step explanation:

To know the discount, we must know how much that $ 18 represents of the original price, as follows:

18/45 = 0.4

That is, $ 18 is 40% of $ 45

Therefore, to calculate the discount we must subtract what represents 45%, that is, 100%

100% - 40% = 60%

In other words, the discount is 60%

Which phrase best describes the translation from the graph y = 6x2 to the graph of y = 6(x + 1)2?
solmaris [256]

The statement which best describes the translation from the graph y= 6x² to the graph of y = 6(x+1)² is; The translation represents a unit shift rightward.

<h3>Which phrase best describes the translation from the graph?</h3>

The translation involved in the transformation of the graph as given in the task content represents a rightward shift of the graph y = 6x² by 1 unit.

On this note, it follows that the translation involved between the two graphs is; a unit shift to the right.
