what are the explicit equation and domain for an arithmetic sequence with a first term at eight in the second term of 5
olga nikolaevna [1]

Answer:

f(n) = 8 -  3f(n-1)

d : {  8 >= x }

Step-by-step explanation:

Basically we know 8 is the first term, so we subtract 3 to get 5 which is the second term. Then we know d = -3. Now we that we established the formula, let's make a domain. We know x can never be greater than 8 so x is always less than or equal to 8.

In each table, determine if y is proportional to x. Explain why or why not.
Marina86 [1]

Answer: yes

Step-by-step explanation:

You’re multiplying every x value by 4 to get the y values

(Someone got mad at me for not including a better explanation so here you go:

x = 3    y = 12..... 3(k) = 12 (divide both sides by three)

k = 4

x = 5   y = 29..... 5(k) = 20 (divide both sides by five)

k = 4

So on and so forth for the rest of the table
