Answer:
Step-by-step explanation:
2x + 3 = 1
Collecting like terms
2x = 1 - 3
2x = -2
x = -2/2
x = -1
X+2y=8
2y=8/2y
=4 is the answer. You’re so welcome
Answer:
recursive:
a(1)=7 a(n)=a(n-1)-3
explicit:
a(n)=7-3(n-1)
Step-by-step explanation:
for recursive you use a(n)=a(n-1) and then whatever the sequence is. Since yours goes down by 3, it would be -3 at the end.
For explicit, you use a(n)= first number in sequence+the difference in the sequence(n-1)
