is already in simplest form.
Answer:
The constant value (often written k) relating amounts that rise or fall uniformly together. It is the ratio of the amounts y and x: k = y/x. Put another way: y = kx.
First, combine like terms:
(6.7+4.3= 11)
-11.6>11+m
isolate m on one side
-11.6-11>m
=
m<-22.4
Solution:
Given:

The zeros of a function are the values of x when f(x) is equal to 0.
Hence,

Therefore, x = 1
The correct answer is OPTION A.
