Answer:

  1) a1 = -5, a(n) = a(n-1) + 2

Step-by-step explanation:

The explicit formula for an arithmetic sequence can be written ...

  an = a1 +d(n -1)

The corresponding recursive formula is ...

  a(1) = a1, a(n) = a(n -1) +d

__

Comparing the above explicit formula to the one you're given, you see that ...

  a1 = -5, d = 2

Using these values in the recursive formula gives you ...

  a(1) = -5, a(n) = a(n-1) +2

4x-16=-20 solve for the x
Vadim26 [7]

Answer:

x=-1

Step-by-step explanation:

4x-16=-20

Get x to one side by subtracting it.

-16=-20-4x

Add the 20 on both sides.

-16+20=-4x

Simplify

4=-4x

4/-4=-4x/-4

-1=x

x=-1

9) State the coordinates of the endpoints of a<br> line segment that intersects the y-axis.
eduard

Answer:

(5,4) and (3,4)

Step-by-step explanation:

A line segment has 2 end points which can be denoted as:

(x_1,y_1) and (x_2,y_2)

When this line segment intersects at y.

This means that the coordinate on the y axis is the same at both end points

i.e.

y_1 = y_2 = y

(x_1,y_1) and (x_2,y_2) becomes (x_1,y) and (x_2,y)

x1 and x2 can be any value but the y value must remain unchanged

Using the above analysis, a possible coordinate is:

(5,4) and (3,4)

Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form (x_1,y)<em> and </em>(x_2,y)<em />

Take for instance, another possible pair is:

(1,-3) and (0,-3)
