Because bases are different.
a^n · a^m = a^(n+m)
A' = (-2, 1)
B' = (1, 0)
C' = (-1, 0)
For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.
Answer:

Answer:
$56,900
Step-by-step explanation:
Given that:
Total sales in March = $151,000
Total variable cost = $94,100
The contribution margin for March can be obtained using the relation :
(Total sales - Total variable expenses)
($151,000 - $94,100)
= $56,900
Hence, contribution March for the month of March is $56,900
