Question:

Soulotion to equation if y is =15 when x=2 ,find y when x=8

Answers

Answer: The value of y for x = 8 is 60  .Step-by-step explanation:Given expression as : For x = 2  , y = 15Let the equation be written with constant k'So, y = k xOr, k = [tex]\dfrac{y}{x}[/tex]∴   k =  [tex]\dfrac{15}{2}[/tex]Now, again For x = 8 equation can be written as    y = k xOr,  y =  [tex]\dfrac{15}{2}[/tex] × 8Or,  y = [tex]\frac{15\times 8}{2}[/tex]∴    y = 15 × 4I.e  y = 60 Hence The value of y for x = 8 is 60  .
