What is the constant of proportionality, and what method did you use to determine this? I'm marking brainIiest so please be honest and don't answer just for the points :(

(A). k = 5. I determined this by adding y and x.

(B). k = 6. I determined this by multiplying x and y.

(C). k = 2/3. I determined this by dividing x/y.

(D). k = 1.5. I determined this by dividing y/x.

step-by-step explanation:

step-by-step explanation:

it is x=-4

step-by-step explanation:

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
