Question

If zº is directly proportional to x and z = 8 when
x = 4, find the values of z when x = 9.​

Answer 1

Answer:

Z = X

Z = X z is 8 when X is 4

Z = X z is 8 when X is 4i.e 8=4

Z = X z is 8 when X is 4i.e 8=4value of X is 9 ,then value of z is 4½

Z = X z is 8 when X is 4i.e 8=4value of X is 9 ,then value of z is 4½i.e 4.5=9
