Answer:

k(-1) = 7.

Step-by-step explanation:

k(-1) is the value of the function k when x = -1.

You read this off the graph.

Find the value of the point on the graph which corresponds to x = -1. From x = -1 on the horizontal axis move straight up until you meet the graph of k. Now look horizontally to the right and read off the value on the vertical

y-axis

You'll find it is 7.

Law Incorporation [45]

Answer:

each barrel has a capacity of 78,75 liters

Step-by-step explanation:

since the sold 8 barrels and assuming that each have the same capacity and are sold to the same price, the total amount he earned is

total earnings = number of barrels * number of liters/ barrel * earnings/liter

R$1,260,00 = 8 barrels * number of liters/ barrel * ( R$9,00- $7,00) /liter

number of liters/ barrel = R$1,260,00/(8 barrels*R$2,00 /liter ) = 78,75 liters/barrel

therefore each barrel has a capacity of 78,75 liters
