According To The Graph What Is The Value Of The Constant In The Equation Below class=

Sagot :

Answer:

B

Step-by-step explanation:

Answer:  A) 20

Explanation:

The equation [tex]\text{Height} = {\text{Constant} \over \text{Width}}[/tex] rearranges to [tex]\text{Constant} = \text{Height}*\text{Width}[/tex]

To find the constant, we simply multiply the x and y coordinates of any of the point shown:

  • constant = x*y = 4*5 = 20
  • constant = x*y = 5*4 = 20
  • constant = x*y = 10*2 = 20
  • constant = x*y = 20*1 = 20

The general equation is y = 20/x, which rearranges to xy = 20.
