Percent change = (new - old)/old * 100
(6/7 - 3/7)/(3/7) * 100
3/7 * 7/3 * 100
1 * 100
100%
.65
13/20
Just simply divide and you get .65
Answer:
Either
(approximately
) or
(approximately
.)
Step-by-step explanation:
Let
denote the first term of this geometric series, and let
denote the common ratio of this geometric series.
The first five terms of this series would be:
First equation:
.
Second equation:
.
Rewrite and simplify the first equation.
.
Therefore, the first equation becomes:
..
Similarly, rewrite and simplify the second equation:
.
Therefore, the second equation becomes:
.
Take the quotient between these two equations:
.
Simplify and solve for
:
.
.
Either
or
.
Assume that
. Substitute back to either of the two original equations to show that
.
Calculate the sum of the first five terms:
.
Similarly, assume that

Answer:
graph{3x [-10, 10, -5, 5]}
Explanation:
this function is in the form of
y
=
m
x
+
q
with
m
=
3
,
q
=
0
so it's an straight line: ascending [
m
>
0
], that touch the
y
axis in the point
(
0
,
0
)
[
q
=
0
]
Answer:
x = 5 & y = 6
