Answer: (-1, 4) is the vertex of the parabola.
To find the vertex when you are given the equation in vertex form, all you have to do is look at the letters k and h. They will tell you what the vertex is.
It is always (h, k)
There is only one trick in this problem. You have to change "(x + 1)" to "(x - (-1))" since the format of the equation requires "(x - h)".
This makes the h value -1 instead of 1.

Step-by-step explanation:
Answer:
The length of side XY is 
Step-by-step explanation:
The picture of the question in the attached figure
we know that
the formula to calculate the distance between two points is equal to

we have that the coordinates of points X and Y are
X(4,2) and Y(3,-3)
substitute the given values in the formula



therefore
The length of side XY is 
Answer:
take 7 from both sides of the inequality which gives 12x <-18
divide both sides by 12 and u get x=-3/2
