Identify the vertex of the parabola. (1, −3) (−4, 0) (−1, −3) (−3, 1)
vfiekz [6]

Answer:

Vertex(-3,1)

Step-by-step explanation:

We have a graphical representation of our parabola.

Showing both the x axis and the y axis and showing the values of each point of the parabola on it.

As we can see we have some major points like point p = (-4,0)

And point q = (-1,-3)

What I want to point out is that every unit represent a two then half of it represents a one.

So the position of our vertex which is the maximum point on the graph

X axis = -3

Y axis =1

So the point our vertex is located

Vertex(-3,1)

Three consecutive even numbers have a sum between 84 and 96.
ELEN [110]

Answer:

a. 84 < n + (n + 2) + (n + 4) < 96

b. 26 < n < 30


Step-by-step explanation:

Let n = 1st number

n+2   2nd  even number

n+4 = 3rd even number

The sum of these 3 numbers is

n+n+2+n+4

It must be between 84 and 96  (it does not include this 84 and 96)

84< n+n+2+n+4 < 96


Now we need to solve this

Combine like terms

84 < 3n +6< 96

Subtract 6 from all sides

84 -6 < 3n+6-6 < 96 -6

78 < 3n < 90

Divide all sides by 3

78/3 < 3n/3 < 90/3

26 < n< 30
