Inverse Proportion. • As one thing increases, the other thing decreases. 1) y is inversely proportional to x. when x=2 y=6 Find the value of y when x=4 yaść y = x → y . 6 + 1/ 10 = 6x2= K k=12 y = 12/02 y=3 Exam Style Questions 1) y is inversely proportional to x. When y=5₁ x=9 2) Work out an equation connecting y and x. you st y=W 5=4 > y = 45 5x9 = K K=45 b) Work out the value of y when x-10 y = 45 X y=455 y = 4.5 2) v is inversely proportional to x². When x=2₁ V=6 Work out the value of V when x-10 va 6°/4/20 K V = 24 V=K² 6 = 1/1/1² 6x4-K K = 24 V - 242 10² 24 100 V V-0.24
