Problem 3: Use Cramer's Rule to solve the following system: 3x+2y=4
8x+4y=8
y -2=2
-x-2=-3
Problem 4: i) 3x +2y + z = 4 ii) 3x +2y + z = 41
5x + 4y = 1
5x + 4y =1
a) Solve the system by using Cramer's rule.
b) Solve the system by using an inverse matrix.

i'm not sure i quite understand, could you provide more information?

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

good luck on ur quiz test or homework. have a good day : )
