Answer:
1/6 ton of fish is fed during the feeding at night.
Step-by-step explanation:
The fish fed in the morning is 
tons, and during after noon the fish fed is 
more than in the morning; or
and let us call the tons of fish fed at night 
, then if the total tons of wish fed during the is 
, we have
Let us add the numerators on the left side and we get:
and subtract 
from both side to isolate 
and since 
, we have
the common denominator of the fractions is 6; therefore, we rewrite the equation as
and subtract the numerators to get:
which the number of tons fed during the feeding at night.

Answer:
-1/2
Step-by-step explanation:
Pick two points on the line
(-2,3) and (2,1)
Using the slope formula
m = (y2-y1)/(x2-x1)
= (1-3)/(2 - -2)
= (1-3)/(2+2)
= -2/4
= -1/2
Answer: g(x) at (70, 55)
Step-by-step explanation:
The minimum of g(x) is lower than f(x) which is (20, 340) and thats obviously higher than (70, 55) so :)
