k = 
using the ' laws of logarithms '
log x - log y = log (
)
logx = logy ↔ x = y
logk - log(k - 2) = log5
log (
=log 5
= 5
5(k - 2) = k
5k - 10 = k
4k = 10 ⇒ k =
= 
(-1/4-1/2)/(-4/7)
= (-1/4-2/4)* (-7/4) (common denominator is 4)
= (-3/4)* (-7/4)
= 21/16
= 1 5/6
The final answer is 1 5/6~
The answer are c. x=-1 and e.x=1
Answer:

Step-by-step explanation:
We need to write the equation in slope-intercept form which passes through points (1/5,-4) and (16/5,-9)
Slope is given formula:

Now plug the value of slope m and any one of the given point into point slope formula:




Now simplify this and write in slope intercept form y=mx=b

Hence final answer is
