The value of y is 18.46 when x=10 and z = 26
Step-by-step explanation:
The direct proportion is denoted as:
y∝x
And the inverse proportion will be denoted as:
y∝1/z
combining both
y∝ x/z
When the symbol of proportionality is removed, the proportionality constant is introduced
Given
y = 32 when x=4 and z = 6
Putting the values
So the equation will become:
Putting x=10 and z= 26
Hence,
The value of y is 18.46 when x=10 and z = 26
