5 0

Answer:

a_1 = 94 \\ a_n = a_ {n - 1}  - 7

Step-by-step explanation:

The given arithmetic sequence is 94, 87, 80, 73,...

The first term is

a_1=94

The common difference is

d = 87 - 94

d =  - 7

The recursive formula is given by:

a_n = a_ {n - 1} + d

We substitute the common difference to obtain:

a_n = a_ {n - 1}  - 7

What is the slope of a line that passes through the points (-4,0) and (0,4)?
CaHeK987 [17]

Answer:

The slope is the change in Y over the change in X.

m = (0 - 3) / (0 - (-4)) = -3 / +4 = -0.75

On a number​ line, suppose point E has a coordinate of -4 ​, and EG = 13. What are the possible coordinates of point​ G?
Ludmilka [50]

Answer:

9 or -17

Step-by-step explanation:

Hello!

The distance can be positive or negative, as we are just counting the number of units they are apart.

To find the possible coordinates for G, we can add or subtract 13 from -4 to find the possible coordinates for G.

<h3>Find G</h3>
  • -4 + 13 = G1
    -4 - 13 = G2
  • 9 = G1
    -17 = G2

The possible coordinates of G are 9 or -17.

2. Find the slope, or rate of change, represented in the table below. x -1 0 1 2 3 У -8 3 14 25 36​
kirza4 [7]

Answer:

11

Step-by-step explanation:

slope is change in y over change in x. so, if x is increasing by one every time and y is increasing by 11, then the slope is 11/1, which we write as 11.
