It says that you need to divide 2 exponents with the same base, you keep the base and subtract the powers, its kind of like reducing fractions! :)
Answer:
B
Step-by-step explanation:
The exponential function 
shows the exponential growth if 
Consider choice B.
If x=1, then 
if x=2, then 
if x=3, then 
if x=4, then 
This means that the function 
represents the table B.
Answer:
450 people were at the match
Step-by-step explanation:
So let's make equation :
W = women
M = Men
C = Children
First equation :
M = W + 250
Second equation :
C = 2W
Third equation :
M = 2(W+C)
Let's substitute the second equation into the third :
M = 2(W + 2W)
M = 2W + 4W
M = 6W
Let's substitute this equation into the first one :
6W = W + 250
5W = 250
W = 50
Now we know that that there were 50 women at the match and can substitute this value for the first equation and then the second :
M = 50 + 250
M = 300
This means that there must have been 300 men at the match.
C = 2(50)
C = 100
This means that there must have been 100 children at the match.
Adding all values together gives us :
50 + 300 + 100 =
450 people were at the match
Hope this helped and have a good day
