Answer:

  c.  x = 7-t; y = -1/(t -7)

Step-by-step explanation:

To find the parametric equation for x, use the equation for t and solve for x.

  t = 7-x

  x = 7 -t . . . . . . add x-t to both sides

__

To find the parametric equation for y, substitute the equation for x.

  y = 1/x

  y = 1/(7-t)

To make this match the available choices, we need to multiply numerator and denominator by -1.

  y = -1/(t -7)

The parametric equations are ...

  x = 7 -t; y = -1/(t -7) . . . . . . matches choice C

Fiesta28 [93]

Answer:

C

Step-by-step explanation:

A is right, D is right because they are on the outside and on different sides, B is actually right since they are on the inside and on different sides, so that leaves c, so this has to be the wrong one because they are not both interior since 5 is on the outside and 6 is inside even if they are both on the same side
