Answer:
z = 1.083
z ≈ 1( that is z is approximately equals to 1)
Step-by-step explanation:
from the question,
z ∝ 1/x
z = k × 1/x........................................... where k is the constant of proportionality
z = k/x
when z = 19
x = 0.68421052631579
k = ?
z = k/x
k = z × x
k = 19 × 0.68421052631579
k = 13
to find the value of z when x = 12
from
z = k/x
z 13/12
z = 1.083
z ≈ 1( that is z is approximately equals to 1)

Answer:
I only
Step-by-step explanation:
dy/dx = x + 1 / y -3
(y - 3)dy = (x + 1) dx
integrate
1/2y^2 - 3x = 1/2x^2 + x
1/2y^2 = 1/2x^2 + 4x
y^2 = x^2 + 8x
y = (x^2 + 8x)^1/2
