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>
Subtract 7 from both sides
x^2 - 6x - 7 = 7 - 7
Simplify
x^2 - 6x - 7 = 0
Answer :
The final solutions to the quadratic equation are:
x = 7, -1
Answer:
The answer to your question is 7 times
Step-by-step explanation:
Data
Percent of accuracy = 35%
Times she is at bat = 20
Times she hit the ball = ?
Process
1.- Use proportions to solve this problem
20 times will be the 100% because is the total number of times she is at bat.
20 times ------------------ 100%
x ------------------ 35%
x = (35 x 20) / 100
x = 700 / 100
x = 7
2.- Conclusion
From 20 times she is at bat, she will hit the ball 7 times.
