y/9 +5 = 0   subtract from both sides 5 and will get 

y/9 +5 -5 = -5

y/9 = -5 multiple both sides by 9 and will get 

y = - 45  so choice C. is right sure 

hope helped

Answer:

C.[tex]y=-45[/tex]

Step-by-step explanation:

We are given that an expression

[tex]\frac{y}{9}+5=0[/tex]

We have to find the value of y

[tex]\frac{y}{9}+5=0[/tex]

Using subtractive property of equality

Subtractive property of equality : When a positive number goes from left side of equal to to right hand side of equal to then the sign changes into negative sign.

[tex]\frac{y}{9}=-5[/tex]

Using multiplication property of equality then we get

[tex]y=-5\times9[/tex]

[tex]y=-45[/tex]

Hence, option C is true.
