The vertex of this parabola is at (-1,-3) which of the following could be its equation

2 answers:

6 0

Since these are parabolas with y being squared, the standard form of such a parabola with vertex at (h, k) is

x = a(y - k)^2 + h 

There are no steps. Just look at what is inside the parentheses and compare it to (y - k) with k = -3. 
Then look at what is added and compare it to h = -1. 

For instance, A has (y + 1) in parentheses. So k = -1. And it has -3 added, so h = -3. That would be a vertex at (-3, -1).

For
y=a(x-h)^2+k
vertex is (h,k)

it could be
y=a(x+1)^2-3

What are the first five terms of the sequence given by the formula an = 4n + 1?

denis-greek [22]

Answer:

5,9,13,17,21

Step-by-step explanation:

We can the values in "n"

a(1)=4(1)+1

a(1)=5

a(2)=4(2)+1

a(2)=9

a(3)=4(3)+1

a(3)=13

a(4)=4(4)+1

a(4)=17

a(5)=4(5)+1

a(5)=21

As you can see, each value consecutively increases by 4, this is also known as the common difference (d).

HELP ME PLS GRADES ARE DUE TODAY

damaskus [11]

9514 1404 393

Answer:

see attached

Step-by-step explanation:

Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change) and "rise" (vertical change) between the marked points.

In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.

The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.

If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)
