Answer:
y = -51 ÷ x
Step-by-step explanation:
The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = -3 when x = 17 and y varies inversely with x.
So we substitute the values y = -3 and x = 17 in the equation y = k ÷ x
K = constant, we have to work this out
-3 = k ÷ 17
-3 × 17 = k
k = -3 × 17
k = -51
k = -51 So then we put this back into the original y = k ÷ x to find our final equation which is y = -51 ÷ x
Answer:
22.67 containers.
Step-by-step explanation:
The number of cars washed is the average by the total hours worked:

Given that each car uses 1/3 tin of wax, the total containers is calculated as:

Hence, the car wash uses 22.67 containers of wax per day.
