the variable z is directly proportional to x. when x is 6, z has the value 18. what is the value of z when x = 10 the variable z is inversely proportional to x. when x is 3, z has the value 2. what is the value of z when x = 13

z[tex] \alpha x[/tex]
Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30

Part B;
Z[tex] \alpha \frac{1}{x} [/tex]
z=[tex] \frac{a}{x} [/tex]
Where x is a constant of proportionality,
when x=3, z=2
2=[tex] \frac{a}{3} [/tex]
a=3*2
a=6
When x is 13,
Z=[tex] \frac{6}{13} [/tex]
