F(x) = 25 - 2x
f(5) is pretty much the value of f(x) when x = 5
Plug x=5 into f(x)
f(5) = 25 - 2(5)
= 15
That's your answer.
Have an awesome day! :)
Answer:
C

Hope this helps
for #1 it is y=-3/2x+4 the -3/2 is the slope and the 4 is the y intercept
for #2 it is y=6/+2 the 6/2 is the slope and the 2 is the y-intercept
the y-intercept is where the line passes through the y axis
