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\(\alpha x\) Z=kX When x=6, z=18, Finding value of z, 18=k6 k=3 Z=3X when x=10, Z=310 Z=30
Part B; Z\(\alpha \frac{1}{x}\) z=\(\frac{a}{x}\) Where x is a constant of proportionality, when x=3, z=2 2=\(\frac{a}{3}\) a=3*2 a=6 When x is 13, Z=\(\frac{6}{13}\)
