3/12 and 8/12
The common denominator is 12
Ok so first equate all the three equations whether by substituting or by eliminating then choose the one das not the answer
Answer:
Your correct answer is option C. -2 (9 + 32n)
Step-by-step explanation:
Solution:
Options are not given in the question
Given First degree expression:
-18-64n
= (-2)×9 + (-2)×32n
Take (-2) common, we get
= (-2)( 9+32n)
Therefore you get your answer of option C. -2(9+32n)
Because α varies directley to β
(k = constant)
α=7 when β=2
7= 2k
k=
so when α=21
21=
b
b= 6
each term is negative and 1/4 of previous term so the nth term is the n-1 term times -1/4 so f(n)= -1/4 f(n-1)
