Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.
Answer:
C.
Step-by-step explanation:
half of y = 1/2 *y
Difference between x and half of y
= x - 1/2 y
Decimal fractions don't exist. Do you mean convert to a decimal and a fraction?
