Answer:
The least number of stamps required is 
Step-by-step explanation:
Let the number of
cent stamps be
and
cent stamps be 
We have

The minimum number is obtained when more
cent stamps are used
Here
cannot be greater than
since 
Substitute 

Not possible since
is not a fraction
Substitute 

Not possible since
is not a fraction
Substitute 

Possible
Hence minimum number of stamps is

Answer:
y = x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 9 ← is in slope- intercept form
with slope m = 1
Parallel lines have equal slopes, thus
y = x + c ← is the partial equation of the parallel line
To find c substitute (6, - 7) into the partial equation
- 7 = 6 + c ⇒ c = - 7 - 6 = - 13
y = x - 13 ← equation of parallel line
Answer:
A) 2 2/3 pages per hour
Step-by-step explanation:
You would multiply 1/4 times 4 to get 1 hour
then you would multiply 2/3 times 4 which is 2 2/3
Answer:
3x+2
Step-by-step explanation:
The polygon is regular ,<em> </em>so all the sides would be equal.
Thus all sides measure same as <u>3x</u><u>+</u><u>2</u>
