Answer:
Graphs C and D show an arithmetic sequence.
Step-by-step explanation:
Arithmetic sequences have a common difference, meaning that the gap between each term in the sequence is always the same.
In Graphs A and B, the gap between terms seems to be changing. That tells us that they aren't arithmetic. Instead, those are geometric sequences.
Meanwhile, Graphs C and D appear to be straight, meaning that the gap between the terms is constant.
N=(3/4)*h*d
--------------------
n=Number of hours she reads
h=Hour(s)
d=Days
--------------------
You see, with this formula - when d=2,
n=(3/4)*h*2=(6/4)*h=(3/2)*h=1.5 hours
So, in the space of 2 days, she had spent 1.5 hours reading.

Answer:
number of dimes is 8
number of quarters is 15
Step-by-step explanation:
let 'd' = number of dimes
let 'd+7' = number of quarters
.10d + .25(d + 7) = 4.55
.10d + .25d + 1.75 = 4.55
.35d = 2.80
d = 8
q = 7 + 8
