Answer: Choice B) -3
------------------------------------------------------
Work Shown:
f(x) = (x+2)/2
f(-8) = (-8+2)/2 ... replace every x with -8; use PEMDAS
f(-8) = (-6)/2
f(-8) = -3
This answer is 135.

Answer:
7/16 C.
Step-by-step explanation:
You need to find the common denominator which in this case is 16...it takes 8, two times to get to 16 which 1 times 2 is 2 so therefore it would 5+2 which is 7 and the common denominator stays the same so it would be 7/16. If you are still confused just private message me and I’d be happy to help if you though this was helpful please mark me as branlist thanks! HAVE A GOOD DAY!!!
Answer:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by
2.1
gives the next term. In other words,
a
n
=
a
1
⋅
r
n
−
1
.
Geometric Sequence:
r
=
2.1
This is the form of a geometric sequence.
a
n
=
a
1
r
n
−
1
Substitute in the values of
a
1
=
5
and
r
=
2.1
.
a
n
=
(
5
)
⋅
(
2.1
)
n
−
1
Remove parentheses around
2.1
.
a
n
=
5
⋅
2.1
n
−
