Which is a counterexample for the conditional statement shown?
Arte-miy333 [17]

Answer: First Option

<em>The points have the same x-coordinate value.</em>

Step-by-step explanation:

By definition, a relation is considered a function if and only if for each input value x there exists <u><em>only one </em></u>output value y.

So, the only way that the line that connects two points in the coordinate plane is not a function, is that these two points have the same coordinate for x.

For example, suppose you have the points (2, 5) and (2, 8) and draw a line that connects these two points.

The line will be parallel to the y axis.

Note that the value of x is the same x = 2. But when x = 2 then y = 5 and y = 8.

There <u><em>are two output</em></u><em> </em>values (y = 8, y = 5) for the same input value x = 2.

In fact all the vertical lines parallel to the y-axis have infinite output values "y" for a single input value x. Therefore, they can not be defined as a function.

<u>Then the correct option is: </u>

<em>The points have the same x-coordinate value.</em>

How to solve this problem by classifying systems of equations<br> 3x+4y=36<br> -5x=35-3y
marissa [1.9K]

Answer:

x=-32/29

y=9\frac {24}{29}

Step-by-step explanation:

3x+4y=36 Equation 1

-5x+3y=35 Equation 2

Multiplying equation 1 with 3 (value before y in equation 2) and equation 2 with 4 (value before y in equation 1) we obtain equations 3 and 4 as follows

9x+12=108 equation 3

-20x+12y=140 equation 4

Subtracting equation 3 from equation 4 we obtain

-29x=32

x=-32/29

To find the value of y, we substitute the value of x into equation 2 as initially given in the equation

-5(-32/29)=35-3y

-5(-32/29)-35=-3y

y=9\frac {24}{29}
