Question

If the distance between (5,-6) and (-7,k) is 13 units then the value of -k is​

Answer 1

Answer:

-k=1

Step-by-step explanation:

√(-12)^2+(k+6)^2

k=-1

Answer 2

Answer:

k=-1, -11

Step-by-step explanation:

distance=√(-7-5)^2+(k+6)^2=13

=√-12^2+(k+6)^2=13

144+(k+6)^2= 169

(k+6)^2=169-144

(k+6)^2=25

k+6=+-5

k+6=+5 k+6=-5

. k=5-6 k=-5-6

k=-1 k=-11
