The two lines have different slopes and intersect at one point in the plane. A consistent system is considered to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide so the equations represent the same line.
Answer:
. r=9 inches is the answer.
Answer:
it's B) 7
Step-by-step explanation:
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
