A circle is shown. Secants S V and T V intersect at point V outside of the circle. Secant S V intersects the circle at point W.

Secant T V intersects the circle at point U. The length of T U is y minus 2, the length of U V is 8, the length of S W is y +4, and the length of W V is 6. What is the length of line segment SV? 6 units 8 units 12 units 16 units

<u>Given</u>:

Secants S V and T V intersect at point V outside of the circle. Secant S V intersects the circle at point W. Secant T V intersects the circle at point U.

The length of TU is (y - 2).

The length of UV is 8.

The length of SW is (y + 4)

The length of WV is 6.

We need to determine the length of line segment SV.

<u>Value of y:</u>

The value of y can be determined using the intersecting secant theorem.

Applying, the theorem, we get;

WV \times SV=UV \times TV

Substituting the values, we have;

6 \times (y+4+6)=8 \times (y-2+8)

   6 \times (y+10)=8 \times (y+6)

          6y+60=8y+48

        -2y+60=48

               -2y=-12

                   y=6

Thus, the value of y is 6.

<u>Length of SV:</u>

The length of SV is given by

SV=SW+WV

SV=y+4+6

SV=6+4+6

SV=16

Thus, the length of SV is 16 units.

Hence, Option D is the correct answer.

No, because if you add on 6 more dollars to package 2 you would only have 6 socks for 12 dollars and on package A you would have 8 pairs for 12 dollars.
