Answer:
y=0.3x
Step-by-step explanation:
Formula =
y α x
y = kx
Where k is the constant of proportionality.
When y = 1.5; x = 5;
We substitute these known values in the equation,
y = kx
1.5 = k5
Dividing both sides of the equation by 5 to find the value for k, we have
1.5/5= k0.3/5
Therefore,
K = 0.3
Having found the value of k,
We substitute this value into the relationship
y = kx
Therefore we have,
y = 0.3x.
The direct variation function is therefore,
y = 0.3x.

The volume of the oil required to fill both containers will be 128 liters.
<h3>What is volume?</h3>
Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width, and height of cube or cubied.
Given that:-
- There are two containers out of which one can hold 31/2 liters of oil while the other can hold 22/3 liters of oil.
- Suppose there are 4 containers of the first type and 9 containers of the second type.
The volume of oil in the first container is liters so for four containers the volume will be:-
V = 4 x
V = 2 x 31 = 62 liters
The volume of oil in the second container is liters.
V = 9 x
V = 3 x 22 = 66 liters
So total volume of oil will be calculated as:-
Total volume = 66 + 62 = 128 liters
Therefore the volume of the oil required to fill both containers will be 128 liters.
