Answer:
see explanation
Step-by-step explanation:
If f(x) and g(x) are the inverses of each other, then
f(g(x)) = g(f(x)) = x
f(g(x)) = f(x - ) = x -
+
= x
g(f(x)) = g(x + ) = x +
-
= x
Hence f(x) and g(x) are the inverse of each other
Answer:
Ella should add lbs of water.
Total weight of syrup lbs
Step-by-step explanation:
Weight:

0.5 -- 1.5%
Write a proportion:
Cross multiply:
Ella should add lbs of water.
