You subtract 16 from each side of the equation.
Then it will say exactly what number 'n' is.
_______________________________________
The equation is n + 16 = 9
On the left side, you subtract 16 from (n + 16) and you have 'n'.
On the right side, you subtract 16 from 9 and you have -7 .
Now the equation says n = -7

sorry I don't know hehe
Step-by-step explanation:
u don't care beach
Well, without any prices, I can’t give you a number. And someone else may have a simpler way to do this.
But we’ll call the original bill x.
After the 10% off coupon, the bill is 0.9x
Adding tax = 0.07(0.9x) + 0.9x
Adding a tip = 0.20[0.07(0.9x) + 0.9x)]
If you have numbers to plug in, put them in a comment below & I’ll help more.
Dividing by a complex number is a similar process to the above - we multiply top and bottom of the fraction by the conjugate of the bottom.
When we ask you the domain of f, you need to search for a forbidden value ?
for example you can't divide by zero, so assume x was equal to seven.
Then you would have f(7) = 7 / 7-7 = 7 / 0 this would be impossible because you can't divide by zero, yes ?
Other than that everything works, so the answer is c : all real values of x such that x ≠ 7
Good Luck
