Answer:

The answer is the option A
1

Explanation:

we have


m>(7)/(12)

The solution of this inequality is the interval------>
((7)/(12), infinite)

All real numbers greater than
(7)/(12)

Remember that


(7)/(12)=0.58 ------> using a calculator

so


m>0.58

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

substitute the value of m in the inequality and compare


1>0.58 ------> is true

therefore

the number
m=1 is a solution

case B)
m=-1

substitute the value of m in the inequality and compare


-1>0.58 ------> is not true

therefore

the number
m=-1 is not a solution

case C)
m=-9

substitute the value of m in the inequality and compare


-9>0.58 ------> is not true

therefore

the number
m=-9 is not a solution

case D)
m=-5

substitute the value of m in the inequality and compare


-5>0.58 ------> is not true

therefore

the number
m=-5 is not a solution
