(please help) will be appreciated

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

What would the rule be for the reflection of y=-3

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
