I would say so, yes this relation is a function because if graphed it passes the vertical line test.
Answer: 2 or 3
Step-by-step explanation:
Which ever line is going through the most points
Answer:
1.39
Step-by-step explanation:
Given the quadratic equation :
2x^2+3x-8 = 0
We could apply the quadratic equation formula :
a = 2 ; b = 3, c = - 8
The formula is stated as :
-b±sqrt(b² - 4ac)/2a
To save computation tune, we could use a calculator :
The roots are : - 2.886 ; 1.386
The positive solution rounded to the nearest hundredth is : 1.39
So these are our two equations: 
Before we can use elimination, subtract y on both sides of the first equation: 
Now we are able to use elimination. To eliminate the y variable, add the two equations together to get
. From here we can solve for x.
For this, just divide both sides by 3 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:

<u>In short, x = 3 and y = 6.</u>
Answer:
-3
Step-by-step explanation:
keep change change such as -6-2 would be -6+-2
