Pleas help me out here.
Amiraneli [1.4K]

Answer:

A and E

Step-by-step explanation:

The given problem shows a graph of a vertical line with an undefined slope, in which its equation is x = 3 (which matches Option A).

It is not considered a function because it has the same input for every given output.  This means that regardless of its y-coordinate, its corresponding x-coordinate will always be x = 3.  

The Vertical Line Test allows us to know whether or not a graph is actually a function. Remember that a function can only take on one output for each input. We cannot plug in a value and produce two output values.  Since the graph represents a vertical line, it automatically fails the vertical line test. Therefore, it is not a function.

Because it is not a function, Options B, C, and D are invalid answers.

Hence, the correct answers are Options A and E.

Write an equation for the proportional relationship. Let X represent a length measured in meters and y represent the same length
anzhelika [568]

Answer:

y=100x

Step-by-step explanation:

Given that x is the length measured in meters and

y represents the same length measured in centimeters.

Let us first have a look at the relationship between meters and centimeters units of length.

1 unit of length in meters = 100 units of length in centimeters

Therefore, it can be said that:

2 units of length in meters = 200 units of length in centimeters

3 units of length in meters = 300 units of length in centimeters

4 units of length in meters = 400 units of length in centimeters

OR

x units of length in meters = 100x units of length in centimeters

It is given that y is the length in centimeters.

Therefore, the <em>proportional equation</em> can be written as:

y=100x
