Answer:
The cost per pound of bananas is $0.84.
Step-by-step explanation:
The question asks to use the given information to set up a proportion and solve for the missing variable. In this case, we know that the cost of 2 1/4 (or 2.25) bananas is $1.89. Since they are asking for cost per pound, we can set up a ratio (fraction):

Since the cost of bananas is the same regardless of the number of pounds, we can set up a proportion to find the cost for just one (1) pound:
Where 'x' is the cost.
Using cross-multiplication and division we get: 2.25x = 1.89. Next, we use inverse operations to divide both sides by 2.25: 2.25x/2.25 = 1.89/2.25. Solve: x = 0.84 or $0.84 per pound.
Answer:
1
Step-by-step explanation:
f(0) is another way of saying 'what is Y when X is 0'. If you look at the graph, when X is 0, Y is 1.
Answer:
6
Step-by-step explanation:
Let x over 126 will equal 1/21.
Therefore,

(f×g)(x) = (fg)(x)
(f×g)=(3x²+5)× (x-2)
use the foil method:
(fg)(x)=3x³-6x²+5x-10
so it is C which is correct
