Answer:
Each point (or pair in a proportional relationship) must share the same difference
Step-by-step explanation:
The graph of a proportional relation is a straight line through the origin. Such a line has the same ratio of y/x everywhere.
A relation in which the difference is constant will be a straight line, but it won't be through the origin. Such a relation is not proportional.
Answer:
P
=
A
1
+
r
t
Step-by-step explanation:
Given
XXX
A
=
P
+
P
r
t
Applying the distributive principle:
XXX
A
=
P
(
1
+
r
t
)
Dividing both sides by
(
1
+
r
t
)
:
XXX
A
1

r
t
=
P
Step-by-step explanation:
-cz+6z-tz=83
z(-c+6-t)=83
z(-c+6-t)/(-c+6-t)=83/(-c+6-t)
z=83/(-c+6-t)
Suppose the one's digit is x, the ten's digit is y. the original number is 10y+x, the reversed number is 10x+y
x+y=13
(10x+y)=(10y+x)-9 =>9y-9x=9 =>y-x=1
Add the two equation to solve: 2y=14 =>y=7
x=13-7=6
the original number is 76.
