Answer:D
Step-by-step explanation:
7(5)-12(5)-5=-45+15
-30 = -30
answer= B. x=5
Answer:
C
Step-by-step explanation:
Given
30( x - 2) + 40( y - 4)
Multiply each of the terms in the first parenthesis by 30 and multiply each of the terms in the second parenthesis by 40.
= 15x - 60 + 30y - 160
= 15x + 30y - 220 → C
All methods are supposed to be correct in most if not all situations and it should not matter if you use a different method given the options
As
, the sequence
converges to zero.
If you're talking about the infinite series
well we've shown by comparison that this series must also converge because we know any geometric series
will converge as long as
