Answer:
The vertex of this parabola is 
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation 
From the function 
, we can see that
This means that
So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.
Thus, the vertex of this parabola is
Answer:
3. 24
4. 10 1/2
Step-by-step explanation:
Answer
y-1=5(x-2)
Step-by-step explanation:
1-(-4) =5
2-1=1
y/x = 5/1 =5
(2,1)
y-1=5(x-2)
x=3
Step-by-step explanation:
x+2=5
x=5-2
x=3
Andrew played for 1 hour and 20 minutes
Lizzie played for 2 hours and 40 minutes
Andrew played for half as long as Lizzie did, so Lizzie played for 1 1/3 hours longer than Andrew did. Hope this helps!
