Answer: Second, third, fifth and sixth options are correct.
Step-by-step explanation:
Since we have given that
[tex]\frac{3}{4}+m=\frac{-7}{4}[/tex]
Now, we will solve it for the value of m :
[tex]\frac{3}{4}+m=\frac{-7}{4}\\\\m=\frac{-7}{4}-\frac{3}{4}\\\\m=\frac{-7-3}{4}\\\\m=\frac{-10}{4}[/tex]
Hence, the value of m is
[tex]\frac{-10}{4}[/tex]
and we can also apply m=[tex]\frac{-5}{2}[/tex]
if [tex]\frac{-5}{4}+m=\frac{-15}{4}\\\\m=\frac{-15}{4}+\frac{5}{4}\\\\m=\frac{-10}{4}\\\\m=\frac{-5}{2}[/tex]
And
[tex]m+2=-0.5\\\\m=-0.5-2\\\\m=-2.5\\\\m=\frac{-5}{2}[/tex]
Therefore, Second, third, fifth and sixth options are correct.
