Answer:
The answer is the option A ![1](https://tex.z-dn.net/?f=1)
Step-by-step explanation:
The options of the question are
A. 1
B. -1
C. -9
D. -5
we have
![m>\frac{7}{12}](https://tex.z-dn.net/?f=m%3E%5Cfrac%7B7%7D%7B12%7D)
The solution of this inequality is the interval------> ![(\frac{7}{12}, infinite)](https://tex.z-dn.net/?f=%28%5Cfrac%7B7%7D%7B12%7D%2C%20infinite%29)
All real numbers greater than ![\frac{7}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B12%7D)
Remember that
------> using a calculator
so
![m>0.58](https://tex.z-dn.net/?f=m%3E0.58)
we know that
If a number is a solution of the inequality
then
the number must satisfy the inequality
Verify each case
case A) ![m=1](https://tex.z-dn.net/?f=m%3D1)
substitute the value of m in the inequality and compare
------> is true
therefore
the number
is a solution
case B) ![m=-1](https://tex.z-dn.net/?f=m%3D-1)
substitute the value of m in the inequality and compare
------> is not true
therefore
the number
is not a solution
case C) ![m=-9](https://tex.z-dn.net/?f=m%3D-9)
substitute the value of m in the inequality and compare
------> is not true
therefore
the number
is not a solution
case D) ![m=-5](https://tex.z-dn.net/?f=m%3D-5)
substitute the value of m in the inequality and compare
------> is not true
therefore
the number
is not a solution
