Hi!
So, to "half" a number, you multiply it by 1/2 or 0.5
"A number" is a number which we don't know the value of, so we could use a variable. Any letter you want is fine, but let's use x

1/2x - 12
Answer:
I think its B
Step-by-step explanation:
I don’t really know but I think one of them would be 150 adding 60 and 90
F(x) = 7x − 13
To find f(-x) , just replace x with -x:
f(-x) = 7(-x) - 13
f(-x) = -7x -13
